What D&D edition has the best random treasure tables?

Thursday, July 9th, 2020

I don’t like edition wars, but let’s have a friendly little edition skirmish. Which edition lets you generate the “best” random treasure? I’ll be judging based on variety/unpredictability of treasure, appropriate matching of combat risk and monetary reward, economy of page space, and number of rolls required.

It may seem like a pointless exercise, but I have a reason for it. I want to figure out what I like about previous designs so I can imitate my favorite.

In my last post, I talked at length about how I don’t like the 5e monetary treasure tables. My conclusion: The developers made a decision to limit treasure rolls to a single d100 roll, and that decision led to unvarying, samey treasure, with wide bands of character levels where treasure values don’t increase. Treasure needs to be more varied between levels, and even within a single level.

I plan to make replacement treasure tables for 5e: tables which preserve the quantity of monetary and magical treasure earned over each adventuring tier, but spread it around in a more natural-seeming and satisfying way.

And, as for every bit of rules-mongering that I do, I want it to fit on one printable page. (5e’s tables take up about 3 pages.) More variety than the 5e DMG, in a third the space? It might be a bit tricky. I’d better do some research.

So, did other editions do any better at letting you roll up interesting, varied, inspiring treasure? I’m not primarily considering magic items here – just the coins and other forms of nonmagical wealth.

first and second edition

Even if you never played 1e, or one of the other TSR versions of D&D, it will probably come as no surprise that its treasure system was a complex, nonsystematic edifice that seemed less like it was designed and more like it evolved. There was no explicit concept of wealth by level in 1e (though since 1 gp = 1 xp, your earned money was roughly equal to your earned xp). There were no treasure charts by level. Instead, there were 26 “treasure types”, labeled A through Z, with no explicit guidance about what each was for. Each monster had a bespoke, customized treasure entry in the monster manual containing zero or more treasure type codes. For instance, hobgoblin treasure is “individuals J, M, D, Q (x5) in lair”. (It’s either treasure or it’s subway directions. J to M to D to Q will get you from JFK airport to my house in Brooklyn.) Generally (but with many exceptions) stronger monsters had more treasure, but in a more naturalistic than mathematical way.

I love how treasure is story-driven with this method. Pirates have rich treasure plus a treasure map! Xorn have a lot of gems! Dragons have a little of everything! The only disadvantage, if it is a disadvantage, is that the intended pace of treasure acquisition was not clear to DMs, and therefore in gp=xp systems, the intended pace of leveling wasn’t made explicit.

The 1e system could require a lot of die rolling for big treasures. On average, for instance, Treasure Type A requires about 20 to 25 rolls, minus any required for figuring out what gems you had. (Let’s assume you didn’t roll separately for all 4-40 gems.) Is this extra work a problem? I mean, it’s not a show-stopper. Generally, keeping the game moving is a plus, but treasure generation might be an exception to that rule. Farm it out to the players! They’ll be happy to do it.

What the 1e treasure matrix loses in economy of die rolls, it gains in economy of space. It takes up a single page in the monster manual! Very tidy.

So that’s first edition. The second edition system is just like first, with a few values moved around, so I won’t treat it separately.

Overall grade: A

Third edition

Third edition was the first time D&D had a rigorous and transparent treasure system designed to get characters the right amount of treasure at each level. Each level had a different set of treasure tables with smoothly ascending cash values. Furthermore, within each level there were variations: at level one, for instance, you might find copper OR silver OR gold OR platinum, with a wide range of possible values for each. (But never two types of coinage together, oddly, unless you lump several treasure rewards together.)

The rigorous, explicit nature of 3e treasure might not appeal to every DM, but as a tinkerer I appreciate it. If I wanted to make up a treasure or reward on the fly for a group of 4th level characters, it’s easy to extrapolate a reasonable value: compare that to 1e, where I have no idea what’s a good-sized treasure for a 4th-level party.

The third edition charts are tidy. They all fit on one or two pages, depending on printing, from level 1 all the way to level 30 (though level 30 is absurdly unusable: same as level 20 but with an additional forty-two major magic items. Still. Pretty good for one page of charts!)

It also required fewer die rolls than the 1e chart, at least at low to mid levels. Instead of rolling on an eight-column matrix, as in 1e, you roll on a three-column matrix. For level 11, for instance, the maximum number of rolls you can make is ten, excluding gem subtables but including magic item determination. Obviously, at level 30, you’ll need at least 42 more rolls for all those major magic items. But I think we can agree they printed that line as a joke and ignore it.

There’s one more thing I like a lot in 3e: it’s the only edition with a “mundane items” table in the treasure section. Especially at early levels, there’s room for useful, expensive items as a treasure reward. The Mundane Items table included expensive armors, masterwork weapons, alchemist’s fire, and the like. It provided upgrades for low-level characters while keeping magic items rare – and also buffed monsters. Kobolds with plate armor and alchemists’ fire are no joke.

Grade: A

Fourth edition

Like third edition, fourth edition had a cash reward progression which increased smoothly every level – better than the big 5e tier-sized blocks of identical treasure. (In 5e, you have exactly the same expected treasure from a CR 5 encounter as from a CR 10 one.) 4e also had nice, organic-seeming groupings of treasure of the kind that you can’t get in 5e. For instance, in 4e, you could find a magic item with no coins; or reasonable-sized groups of one or two gems instead of 5e’s bunches of 7 at a time; or a treasure consisting only of gems.

Fourth edition’s 20 charts took up three and a half pages: about the same amount of space as is required for 5e’s four charts. Not too bad.

And I believe 4e is the edition that came up with the idea of leveled grades of gems. In previous editions, a gem was a gem was a gem – identical to any other until you rolled on a separate chart to determine its value. For instance, in third edition, at level 1 you have a 5% chance of finding one gem, and at level 20 you have a 35% chance of finding 4d10 gems. But a gem found at any character level had the same average value. Even at level one, you might roll high on the gem table and get a 5,000 gp diamond.

That appeals to the gambler in me, but the 4e way is more buttoned-down. At low levels, you found onyx, and at high levels you found star rubies and astral diamonds.

So the 4e system had a lot going for it! However, there was one slight problem. 4e didn’t actually have a system for random treasure. There were no tables to roll on: you selected from fixed-value “treasure packets” for each level. Individual treasures were quite varied, but the amount of treasure per level was completely predetermined. So as decent as 4e’s treasure handouts were, we can’t use them as a guide for making new random treasure charts.

Grade: Incomplete

Fifth Edition

I cover 5e exhaustively here and it gets a C.

and the winner is…

Much as I love the treasure-type system of the early editions, I think the third edition treasure tables are my favorite. There’s an argument to be made either way. You might prefer the esoteric and monster-story-driven treasure types of 1e to the mathematical precision of 3e. 4e (no random treasure) and 5e (unvaried magic treasure) are decidedly inferior to those two.

can we improve 5e?

In my next post, I’ll build a new treasure table for fifth edition, using third edition as my jumping-off point. It’ll offer varied treasure, with different payouts for each level, and it’ll grant the same amount of overall treasure as the current 5e tables do. As a bonus, I want to make it compatible with very large or small adventuring parties (no edition’s treasure tables were designed with solo play in mind). And I’ll add mundane treasure.

If possible I’d like it to fit on one page, so you can print it out and tape it in the back of your DMG. Not guaranteeing a huge font though!

I’ll also build these rules as an option into my Inspiration app, so you can have better treasure when you’re DMing from your phone.

why the 5e treasure tables aren’t very good (and how they got that way)

Wednesday, June 24th, 2020

I’ve been running D&D 5e dungeon crawls lately (testing my Inspiration app) and one thing jumps out: by-the-book treasure isn’t nearly varied enough.

treasureguysI’m not talking about magic items: sure, I’m a little sick of potions of giant strength, but D&D has a generosity with its magic item list that I very much appreciate (more than 300 items in the DMG!). I’m talking monetary treasure.

This problem doesn’t come up much in my regular D&D campaigns, because neither I nor my co-DMs use the loot tables in the 5e DMG. After all, there’s not much to spend money on in non-houseruled 5e, so you can make up literally any amount of money and it makes no difference to game balance.

Even without much to buy, discovering treasure still is (or should be) fun. As a DM, I’ve always liked rolling on treasure tables, and as a player I like uncovering exciting caches of gold and jewels. But when I stick to the letter of the law, as I’m doing in this playtest, the defects of the 5e treasure tables become apparent.

In the course of a recent dungeon delve down to level 3 of a random dungeon, I’ve written down the treasure hoards we’ve found. Here are a few of them:

On level 1, we found: 2500 CP, 900 SP, 90 GP, 6 50-gp gems.
On level 2, we found: 2100 CP, 1100 SP, 80 GP, 6 50-gp gems.
On level 3, we found: 2100 CP, 1100 SP 60 GP, 5 10-gp gems.

When I listed them out like this in my notes, it became clear to me that, apart from magic items, every treasure I found was going to look exactly the same. Around 2000 copper. Around 1000 silver. Around 100 gold. Maybe 6 or so handful of gems or art objects. Every. single. time.

There are a few main problems with cash rewards in 5e:

Lumpy progression.

There’s not a new chart every level. You roll on the exact same treasure chart for all encounters from CR 0 to 4, and then graduate to the next chart up, which you use for six more levels, and so on. Each treasure table generates a coin value ten times the last one – a huge jump. It’s too big a jump, too infrequently. If the devs had found a way to divide this increase evenly over every level, then each level could have been worth 50% more than the last: a noticeable increase each level, and one that gives meaning to choices about challenging an easier or harder foe. (Right now, four bugbears have the same expected treasure trove as four kobolds. Level 3 of the dungeon has the same treasure as level 1. Why venture deeper?)

Samey treasure.

Every treasure hoard of a given tier group has exactly the same coinage mix. For all of CR 0-4, it’s impossible to roll up a treasure hoard containing electrum or platinum, and it’s impossible to roll one WITHOUT about 2000 copper, 1000 SP, and 100 GP. There’s a bit of variation when it comes to the gems and art objects rolls, though you will never find a solitary gem or art object (the smallest number of either you can find is 2d4, and the average is 7).

You’ll also never find a cache of gems or a magic item without some attendant cash. Every randomly rolled treasure must contain money. After the Lady of the Lake raises her arm from the water to give Excalibur to Arthur, she also tosses 42,000 gp and 28,000 pp ashore.

There are more interesting variations in the “individual treasure” tables, but unfortunately that’s all pocket change.

No big scores.

There’s little roulette-wheel drama in 5e monetary treasure: no sense that you could stumble on a big score (except by DM fiat). The only meaningful variation is in whether you get gems or art objects, and how many of each. On each treasure table, the best gem or art object result occurs about 20-30% of the time, so it’s not particularly unusual; and apart from the lowest tier of play, the best possible gems/jewelry roll can increase total treasure value by about 10%, so it can almost be ignored.

The ninja rule.

you know what? The minor point that I mentioned before, that you can’t roll up a single gem or art object, is actually a big problem for me. A single well-described piece of jewelry or idol, or a fist-sized emerald with a strange flaw, could grab someone’s imagination. However, gems and art objects generally come in packets of seven. Rolling up and describing seven art objects is an exercise in tedium for the DM and player.

DM: … encrusted with rubies; and, finally, a goblet etched with a baronial shield and the motto EVER TRIUMPHANT.
PLAYER: ….. ok, so… seven art objects worth 2500 each, get it. (instantly forgets every detail)

Since gems and art objects are just interestingly-described cash, there’s no point in presenting them in numbers that repel description. I might make up one or two interesting art objects that give flavor to my setting, but not seven.

Why is 5e like this?

I’m not sure exactly what was going on with treasure tables during the development of 5e, but I think that most of the problems stem from a single design decision: making the treasure tables require only one percentile roll to generate the whole treasure.

Take a look at one of the treasure tables, the one for CRs 11-16.

Screen Shot 2020-06-23 at 4.41.41 PM

After a single d100 roll, you know almost everything about the treasure: what types of coinage you get; the number and denomination of gems and jewelry; and what magic item tables to roll on. Compare that with, say, the 3rd edition level-11 table, which required 3 d100 rolls: one for coin type, one for art/gems, and one for magic items.

Screen Shot 2020-06-23 at 4.50.46 PM

I think the decision to go down to one d100 roll in 5e had to be a deliberate choice. But it was one with some bad consequences.

No roll for coin type

In the 3e chart, you roll to see if you get silver, gold, or platinum. (It’s a little weird that you can’t get a mix of coins, but whatever.) Each of the possible coin types had a slightly higher average value, so rolling a higher-denomination coin was better.

In the 5e chart, you always just get gold and platinum, no roll required, and no variation between treasures.

Combining the art/gems and treasure roll

Look how big the 5e 11-16 treasure is! There are 33 rows. It takes up almost a full print page. And if you look closely, it’s not super varied. The 32 rows of the “gems or art objects” column are just alternating the same four entries over and over again, eight times. The 28 rows of the Magic Items columns are just repeating the same seven entries four times each.

In fact, this table looks like it was derived by listing out all the permutations of two much tidier tables. These tables don’t exist in print but I’m confident they looked like this:

gems and art objects: roll 1d20:
1: nothing
2-6: 2d4 (5) 250 gp art objects
7-11: 2d4 (5) 750 gp art objects
12-15: 3d6 (10) 500 gp gems
16-20: 3d6 (10) 1,000 gp gems

magic items: roll 1d20:
1-3: nothing
4-6: Roll 1d4 times on Magic Item Table A and 1d6 times on Magic Item Table B
7-12: Roll 1d6 times on Magic Item Table C
13-15: Roll 1d6 times on Magic Item Table D
16 Roll once on Magic Item Table E
17 Roll once on Magic Item Table F and 1d4 times on Magic Item Table G
18-19 Roll 1d4 times on Magic Item Table H
20 Roll once on Magic Item Table I

If you map the permutations of these two charts onto one d100 chart, it perfectly recreates the existing 5e table, bar rounding error.

The big problem is, the two charts, while they require an extra roll, are more economical of space. If the two tables were printed side-by-side, as was done in 3e, you’d only use 8 rows instead of 33.

page count matters

Combining every treasure and art/gems roll into a single roll matters a lot because it balloons the space requirements for a single treasure table. And, since book pages cost real money to print in an already fat book, you just can’t include a lot of these huge tables.

It takes more than half a page, on average, for each of 5e’s four treasure hoard tables. If you had one such table per Challenge Rating from, say, 0 to 21, that would mean devoting 12+ book pages just to treasure charts. That would mean cutting 10 pages of other content.

On the other hand, if they’d used separate d100 rolls for art/gems and magic items, as in 3e, they could probably have fit 22 such charts in around 3 pages.

So, once they’d decided to present giant treasure tables that required only a single roll, there was a real-world economic incentive to cut down the number of tables to four, one per tier.

Does limiting treasure tables to one d100 roll even make sense?

I’ve posited that the developers made a decision to limit monetary treasure generation to a single percentile roll. Is that even a valuable goal?

Not in my opinion.

First of all, once you make your percentile roll, there are still secondary rolls required to determine how many coins, gems, and art objects you find: 4d6x1000 gp, 3d6 500-gp gems, etc. The averages are given: “4d6 x 1000 (14,000) GP”. But you have to roll, or otherwise vary, these amounts. You can’t just take 14,000 every time.

According to the DMG: “Over the course of a typical campaign, a party finds treasure hoards amounting to seven rolls on the Challenge 0-4 table, eighteen tolls on the Challenge 5-10 table, twelve rolls on the Challenge 11-16 table, and eight rolls on the Challenge 17+ table.” Imagine if a DM didn’t roll, and used average treasure for all of these monetary rewards. From around levels 5 to 10, the party would find eighteen consecutive treasures with exactly 700 CP, 7000 SP, 2100 GP, and 105 PP. The treasure coinage is already noticeably lacking variety even if you do roll; if you don’t, it would be comical. The same is true for gems and art: you’d always find either 5 or 10 of each.

So, assuming we are rolling for coinage and gems/art, we’re always making three or four extra rolls in addition to our percentile roll.

And that’s not even counting magic items! Look at the 5e CR 11-16 chart above. There is a lot of percentile rolling here! Some of the entries call for rolling up 1d4 magic items from one table, and 1d6 from another. Each of these d4 and d6 rolls requires further percentile rolls, so, on average, this table entry requires an average of eight rolls, most of them percentile rolls. Taking the table as a whole, you make an average of three and a half extra rolls to determine magic items.

In total, a DM is actually making around nine rolls to determine each CR 11-16 treasure. Saving that one extra percentile roll didn’t make much of a difference.

looking backwards to go forwards

So now that I’ve exhaustively detailed my problems with 5e’s monetary treasure tables: can we do better?

I think so. I’d like to scrap the four 5e treasure tables and make (at least) twenty new ones. I think the in-game economics of 5e are fine as far as they go, I just think the tables could be presented better and the lumpy parts smoothed out.

In my next post I’ll look back at previous editions to see how they did treasure, and we’ll see if we can find the best model for how we’d like 5e treasure tables to look.

5e Inspiration android beta test 1

Monday, May 4th, 2020

I just released the first Android beta test for Inspiration 5e. This test concentrates on dungeon exploration, levels 1 to 7.

You can download the APK [Jun 2 Edit: I’ve removed this build, in preparation of releasing a new build with fixes and new features]

Installation instructions: Follow the link above. You’ll need to say OK to install an untrusted app, and grant permissions for the app to look at your contacts and location. Note: I don’t save or share this information. I ask for photo permissions so that I can allow you to share a bug screenshot with me. I don’t use or look at location data at all, and I don’t know why the app asks. I’ll fix this in future versions.

Here’s what I’d like you to test:
-Turn on Map Mode and explore a dungeon
-Browse for a monster or spell

Here’s what I’d like you to tell me:
-Is it obvious how to save or reroll dungeon rooms, encounters, and treasure? With Map Mode on, is it obvious how to explore the dungeon?
-Is it obvious how to look up a monster or spell?
-When you restart the app, are your settings and Saved items saved?
-What are your biggest annoyances?
-Any suggestions or feature requests?

the inspiration iphone playtest, and a new way to build encounters

Wednesday, April 8th, 2020

Last weekend I did a playtest release for Inspiration. I ended up only doing a release for the Iphone: I figured I’d see if there were any huge show-stoppers before I bothered everyone with an update.

I’m working on a phone app for DMs called 5e Inspiration. It’s a tool for populating your game world with people, locations, maps, monsters, and treasure. Learn more!

I got very encouraging feedback: besides some UI issues, I got a lot of requests for features which I already know I need, and are already on my upcoming feature list. So I’m putting a week or so of work into polishing the UI and adding a few of the most-desired features. Once that’s done, I’ll release a playtest to Android users.

Here’s the big feature I’m adding: a random encounter generator for every monster.

Up until now, Inspiration has only offered the traditional type of random encounter generator, by terrain type, the way print Dungeon Masters Guides always did it. You’re wandering through the forest, you’re level 5, what monster do you run into? That’s useful at times, but as a DM in the middle of a game, I frequently know what kind of monster I want to use; I just don’t have time to use the official encounter-building tools to create a balanced encounter for the party’s level.

Screen Shot 2020-04-08 at 1.32.29 PMOn each monster’s stats page, I’m adding a tool where you can choose a terrain and the desired Challenge Rating of the encounter, and it will make an encounter for you, potentially including appropriate allies, pets, minions, traps, and other complications.

To do this, I’ve made a web of relationships between the D&D monsters. Hobgoblins, for instance, are most often led by hobgoblin captains or hobgoblin warlords, but might sometimes be led by a bugbear or an evil mage or knight. Similarly, hobgoblins frequently employ goblins as cannon fodder, but might also use worgs, ogres, or even ballistas and catapults.

I think it’ll be super useful to be able to instantly whip up, say, a CR 5 goblin encounter (such as 20 goblins with their 5 giant rat pets, led by a bugbear, skulking behind a pit trap), a CR 14 mage encounter (an evil mage with 6 minotaur servants among explosive runes traps) a CR 16 bone devil encounter (one bone devil with its six cambion spawn), or whatever else you need to fit your story.

I’m almost done updating each monster with its potential minions, bosses, and pets. Then after a little testing of my own, I’ll send out an Android playtest. Looking forward to see if you guys like it.

launching the Inspiration beta!

Thursday, March 26th, 2020

Like a lot of folks, I’ve been cooped up inside with no D&D, which made me decide 2 things:

1) now is finally the time to release my free 5e Inspiration app beta
2) it should support solo play.

Screen Shot 2020-03-26 at 10.40.34 AMI’ll be sending out beta invitations this week. Sign up here if you haven’t already!

Beta 1 will include dungeon adventures only, from levels 1 to 7. It will support any number of players from 8 all the way down to 1. 5e Inspiration is designed as a DM aid, but it can also be used as a DM replacement if you don’t have another player on hand. The app gives you dungeons full of locations and encounters; you just have to run the battles yourself.

Here are the questions to think about when you try on the beta:

1) Is it clear how to use the app? Are there any user interface elements that are confusing?
2) Could you easily find all the information you need to run battles, traps, and other encounters?
3) How is solo D&D? Is the balance good? Any player deaths? Did you get rich?
4) Any bugs?

I’ll be sending out beta invitations this week. A few days later, I’ll send out a survey.

I hope this app gives you some D&D fun even if the pandemic is keeping you from doing other fun things you’d like to do. And I hope you’re well, and safe.

why do wizards need to be rare?

Monday, February 3rd, 2020

In most fantasy universes in which people cast spells, magic is a talent that few are born with. No matter how much they study, some people will never be anything but muggles, while other people are born with the Talent or the Gift or a high midichlorian count or whatever.

There are a number of reasons why this choice makes a fictional setting more coherent and focused.

  • A world where magic is common is super bizarre and unfamiliar.
  • Magic is rare to make your wizard protagonist special.
  • Wizards are super powerful: if everyone could learn magic, everyone would.
  • However, these reasons don’t really apply to D&D, which has never had any pretensions at being a coherent and focused fictional setting.

    D&D is a world where magic is common. Most of the D&D classes are spell-users to some degree. Most of the monsters have spells or magical abilities. You might assert that offscreen, within the borders of civilization, magic is rare, but the players’ game experience don’t really speak to that assertion one way or the other. The fact is that in D&D as it’s played, the world is chock-full of magic knapsacks, resurrection magic, and fireballs.

    Your wizard isn’t special. If you come up with some demographics that specify that, say, only one in every thousand people has an arcane gift that can be nurtured, you fall afoul of the fact that nearly every D&D party has a wizard, or a variation like sorcerer, warlock, or bard – not to mention the clerics, paladins, rangers, monks, and druids also in the party. I’ve been playing D&D for decades, and I’ve seen a lot of wizard characters, and if they’re all rare and special, they’re the most common rarity there is. When a wizard character dies, we know we can go back to town and pick up another one if we want. We might claim they’re rare in the campaign setting, but they’re not rare in the game. Furthermore, most players don’t want their wizard characters to be feared, or hunted as witches, or even venerated as demigods every time they come to a new town. Every game session of D&D doesn’t have to be the X Men mutants vs. the world. Just leave me alone and let me do my shopping! Therefore, a blase attitude to spellcasters is pretty common among NPCs: the sort of attitude that comes from familiarity.

    Your wizard isn’t super powerful – at least not at first. In any edition, a first- or second-level wizard isn’t any more powerful than a fighter, and might be significantly weaker. Sure, a first-level wizard can drop a fighter, and a crowd of commoners besides, with Sleep or Burning Hands, but a fighter can drop a wizard with one hit. It all comes down to who wins initiative. And besides criminal assault with Sleep and Burning Hands, what can a novice wizard do that’s any use? They might be able to get a middle-class job as a repairman (Mending), a mortician (Gentle Repose), a locksmith (Knock and Arcane Lock) or a charlatan (Charm and Disguise Self). They might rightly be regarded with suspicion, but not necessarily with awe. Being a low-level wizard might be kind of like being a grad student. It takes years of study, and might lead you to a respectable career some day, but no one’s really jealous of you right now.

    There’s one more reason to avoid the “some people have the Gift” trope, at least for the 5e wizard class specifically. It steps on the sorcerer’s toes. The sorcerer’s story is all “I have a special inborn gift that lets me set things on fire.” Sorcerers are not much of a foil for wizards if the wizard’s story is “I too have a special inborn gift. Mine lets me set things on fire after five years of school.” I much prefer the more democratic message that anyone can go to school, make something of themselves, and learn how to set things on fire.

    1st-level wizard spells for the masses

    Given all this, I say: Open the arcane floodgates wide! Let anyone into the Arcane University, PC or NPC, from muggle or wizard family, so long as they can pay the tuition. The real limitations on wizard power are more insidious: not everyone has the wealth and leisure to attend wizard college, and, as is true for any other character class, most people stay low level. Few survive, or care to brave, the dangerous adventures required to become even, say, third level and unlock second-level spells.

    Therefore, first-level wizards (and clerics, and bards, and other learned spellcasters) might be as common as educated people in our own medieval or renaissance times. Imagine a Shakespearean England where every Oxford scholar can cast Shield but not Suggestion, every vicar can cast Cure Light Wounds but not Lesser Restoration, and every minstrel can cast Charm Person but not Detect Thoughts. Would it really be that different from the standard D&D world?

    low-level spells and society

    Would this turn your world into Eberron, where magic is commercialized and ubiquitious? Not really. In fact, it’s surprising how much first-level spells resist the assembly line. A world where first-level spells are common actually resembles the medieval world that medieval people thought they lived in. You go to your local cleric for healing, blessings, and the detection and turning of minor demons. You go to the local witch for curses and curse removal. Really, Create Water and Purify Food and Drink are the only first-level spells we’d think of as being economically exploitable, and they’re small-scale.

    Second-level spells offer a bit more room for altering society. I believe that lighting cities with Continual Flame is a classic Eberron move. Detect Thoughts and Zone of Truth could change the justice system. Lesser restoration – LESSER restoration – cures all nonmagic diseases, making a 3rd-level cleric better than the best 21st century hospital.

    If third level spellcasters are dirt-common in your campaign world, you might stray a bit from the standard D&D pseudomedieval assumptions. But I don’t think you’ll do your campaign world any harm by allowing a Magic Missile-toting scribe in every village and a Cure Wounds-casting cleric at every roadside shrine. If anything, you’ll bring it more in line with the actual high-magic D&D gameplay that I’ve experienced, where no one blinks at the arrival of a traveling wizard, and someone in town can lift the curse on your fighter – for a price.

    how the “odd detail” can make D&D traps way more fun

    Tuesday, December 17th, 2019

    Traps are kind of an unsolved problem in 5e D&D (of course, I said this before about 4e). On the one hand, you can’t leave traps out, because they’re an integral part of the dungeon delver fantasy. On the other hand, the way they’re usually used in 5e is not fun. Your stock 10-foot-pit trap is (if your passive Perception is high enough) a piece of scenery hardly worth mentioning, or (if your passive Perception is low) an unavoidable hit point tax, or (if your DM doesn’t use Perception) a guess-what-the-DM-is-thinking game, or (if overused) an incentive to play in a laborious and dull style involving ten foot poles.

    Even the writers of 5e don’t have a lot of faith in traps. Consider their advice from Xanathar’s Guide:

    If your encounters or adventures are sown with too many traps, and if the characters are victimized over and over again as a result, they are likely to take steps to prevent further bad things from happening. Because of their recent experience, the characters can become overly cautious, and you run the risk of the action grinding to a halt. Traps are most effective when their presence comes as a surprise, not when they appear so often that the characters spend all their effort watching out for the next one.

    tumblr_pe8yfykwzp1ro2bqto1_500I think this is wrong. Call me naive, but I think traps can be fun. Don’t be stingy. Slather them on! Run an all-trap dungeon. Run an all-trap adventure! If you’re willing to put a little extra work into it, there are ways to make each trap into an entertaining encounter.

    I’ve been the victim of many traps in my years of playing D&D (and also inflicted a few as the DM). Sometimes, defeating a trap can feel extremely satisfying, and even falling victim to a trap can be a hilarious table moment. It all comes down to warning the players, implicitly or explicitly, that they might be walking into danger.

    Here are the setups of some of the traps I’ve enjoyed most as a D&D player. We’ll get into the trap solutions later on.

  • In the dungeon corridor ahead, a glowing dagger floats in the air.
  • A glass tube extends from the floor to the ceiling. Inside the tube is a statue holding an apparently magic weapon.
  • A room contains 4 rotting sofas, several throne-like chairs, vases, and urns which are dented, chipped and broken, stands, small tables, and braziers, all jumbled together.
  • player skill vs character skill

    The traditional trap dichotomy is between old school “player skill” style and new school “character skill” style.

    The “player skill” school holds that characters should perform certain intelligent actions to avoid traps – prod every floor with a pole, throw a coin onto the metal floor, pull the lever with Mage Hand while standing across the room.

    The “character skill” style relies on die rolls. Your characters are more competent adventurers than you are – a character with high Perception shouldn’t miss an obvious trap because their player didn’t guess what action the DM expected them to take.

    In most D&D situations, player skill vs. character skill is a false dichotomy. If you want to get up a cliff, you can either use an Athletics check or do something clever with ropes. If you want to convince a guard to let you pass, you can make a Persuasion check or you can say something reasonable. There are many solutions to any problem.

    Traps don’t have multiple solutions because they often don’t present themselves as problems – by the time you know there’s a trap, the encounter is over. Traps exist outside the usual D&D action loop, which is described in the PHB as:

    1. The DM describes the environment
    2. The players describe what they want to do
    3. The DM narrates the results of the adventurers’ actions

    The trap action loop is more like this:

    1. The players blunder without warning into a trapped area
    2. The DM compares passive perception to static DCs and describes the PCs avoiding or triggering the trap
    3. the players write down damage on their character sheet, or take some trivial action like walking around a pit or stepping over a tripwire

    That’s why the trap-sprung-without-warning doesn’t work very well. When you remove the player’s ability to react to a situation, D&D becomes a game about comparing passive DCs or about performing methodical danger-avoidance routines – and the game begins to fall apart.

    Traps work best when they’re telegraphed.

    The odd detail

    Remember the list of my favorite trap setups I gave above? The common thread: they all include an odd or mysterious element that invites exploration.

    The odd detail can be an obvious clue to the nature of the trap – rubble on the floor below a collapsing ceiling trap, or a dead thief near a poison needle trap – but it can also just be a specific detail that cries out for investigation: a chalked arrow on the floor, or a door painted with a woodland scene. It doesn’t matter much what the detail is, just so it stands out enough to attract the players’ interest.

    It might seem like telegraphing every trap makes it too easy on the players. After all, players can just choose to ignore or steer around anything with a suspiciously lush description. Not to worry! Odd details are like catnip to D&D players. Characters come from miles around to stick their heads in the sphere of annihilation trap.

    The odd detail is the missing piece of D&D traps because it indicates to the players that there’s something to actively investigate. Without it, traps are just something DMs inflict on characters. You’d much rather have traps be something the characters inflict on themselves!

    investigating traps

    How do characters deal with traps? Once you’ve indicated that there’s something that may be worth investigating, the players can choose their own course of action. All the DM has to do is react. This brings traps back into the classic D&D paradigm from the PHB: the DM describing a scene, the players stating their actions, and the DM adjudicating the results. As an added benefit, players can organically choose between using old-school player skill and modern character skill, just as they can in other open-ended D&D scenes.

    Given a suspiciously odd detail, players will generally act in one of three ways:

  • call for a general perception check. “I examine the lacquered cabinet and its surroundings,” or just, “I make a perception check.” The player is choosing to use character skill, not player skill, here, and that’s fine. On a success, the player spots the trap trigger but doesn’t necessarily learn how to disarm it, or even what it does (though it may be obvious.) On a perception roll failure, the character has to try something else. Note: if several characters make nonspecific perception checks, use the rules for group checks! Otherwise, success is all but assured in the most boring way possible.
  • examine something specific, or ask a specific question. “Does the cabinet seem to be locked or sealed in any way?” I tend to reward specific inquiries with automatic success. “No, there’s no lock on the cabinet.” If the player wants to engage the trap using their player skill, I want to honor that choice by putting away the dice.
  • blunder forward because they weren’t paying attention to the DM’s hints. In his article The Flow of Trap Detection, Sly Flourish notes that half the time, D&D players aren’t understanding the DM’s description. That’s such an important point that it should be printed on DM screens. Let’s call it “Sly’s Law of Comprehension.” Frequent misunderstanding is a fundamental part of the medium, and usually neither the player’s nor the DM’s fault.

    So when a player inevitably misses a hint and walks into a trap, does that mean that they deserve to be spanked with inevitable trap damage? No! Here’s where passive perception finally comes into play. If the character ignores hints and blunders towards a carefully-clued trap, the DM can use their passive Perception to give the character a chance to spot the trap trigger.

  • countermeasures

    Once players are aware that they may be in the presence of a trap, they have two choices.

  • Make a skill check to disable the trap. This is putting their character’s survival in their character’s hands. It’s probably the most common approach in 5e, and it’s probably the safest as well.
  • take a specific action which seems logical to them at the time. Players can use their “player skill” to take methodical, brilliant, or wildly ill-considered actions. Such actions should usually either succeed or fail depending on what seems logical given the trap setup. No die roll is required. If Chewbacca chooses to grab the suspicious trap bait hanging from the tree, he ends up triggering the net trap. (He still gets a saving throw, though.) If Indiana Jones throws sand on the invisible bridge, he, or anyone else, can cross it without making a Perception check or taking a leap of faith.

    Sometimes, the DM’s “odd detail” will clue players in to act cautiously. Other times, the details will act like bait, suckering them into dangerous actions. And that’s OK too. It can be fun to disarm a trap with your brain, and sometimes it can be just as much fun to disarm it with your face. Everything’s better when you have agency.

  • What I’m suggesting involves work for the DM. Basically, every trap becomes a micro-puzzle. D&D is flexible: players who don’t relish puzzle-solving can roll a few dice to have their characters solve it. But whether the players take a new-school or old-school approach, every trap is the better for a few memorable, specific details.

    trap solutions

    Here are the “puzzle solutions” to the traps I mentioned at the top of the page.

  • “In the dungeon corridor ahead, a glowing dagger floats in the air.” This happened in Mike Mornard’s game. My thief heedlessly reached out to grab the dagger and ran into a gelatinous cube. I felt that the encounter was fair because I inflicted danger on myself by acting incautiously. If there had been no floating dagger, no clue to the gelatinous cube’s presence, it would have just felt like DM fiat.
  • “A glass tube extends from the floor to the ceiling. Inside the tube is a statue holding an apparently magic weapon.” My buddy John ran this as part of an all-trap dungeon, a museum where the traps themselves were the exhibits. Most were from Grimtooth’s Traps.

    In this trap, the glass tube is filled with poison gas: break the glass and get a faceful of poison. I suspected something of the kind, so we summoned some kind of canary-like creature into the tube to prove that it was poison, and then broke the glass and grabbed the treasure from afar. Mage Hand was involved, I believe. We had a blast and felt really smart solving this one.

  • “A room contains 4 rotting sofas, several throne-like chairs, vases, and urns which are dented, chipped and broken, stands, small tables, and braziers, all jumbled together.” This one is from the original Tomb of Horrors, which has some unfair traps, but this, I think, is a fair one. After a few minutes in the room, the floor will start to jump and buck around, tossing the furniture and characters wildly, and inflicting minor damage on the characters. The Pop-O-Matic action of the trap is a great explanation for the bizarre state of the room.
  • training your players

    Players need to learn that every trap will be marked with a clue. No matter how many traps you spring, that will prevent them from wasting their time searching barren rooms for traps. “You’re in a ten by ten room. Door to the left, door to the right.” There must NEVER be a trap in a room described like this! There’s nothing interesting or off-beat that signals that this is an investigation scene.

    Players also need to learn that there can be benefits from interacting with weird elements in your dungeon. Otherwise, every suspicious scratch on the floor will make your players run the other way. Luckily, D&D has a strong built-in slot-machine-like reward system. Treasure! In standard 5e D&D, about 1 in 5 monster encounters come with a treasure hoard, and lots more carry some incidental treasure. Treat traps just like any other encounter. It’s easy to litter treasure around a trap:

  • The trap was set up to guard the treasure! Guarding valuebles is, after all, one of the most likely uses for a trap.
  • A previous victim of the trap has a sack full of treasure! Nothing says “search this area carefully” like a dead thief.
  • The treasure is the trap’s bait! The “odd detail” is the treasure itself, clearly in sight, although all is not as it seems.
  • traps in the Inspiration app

    Of course, my Inspiration app is chock-full of traps. I’ve got something like 80 trap types, from the basic pit trap to the rolling boulder to the demon-possessed item, and each trap is further detailed with 3 or so “odd details”. That’s something like 250 unique traps. None of them are very complex, but I hope they’re just puzzling enough to give your players a moment of uncertainty.

    Here’s how I construct the traps, and here are some samples for use at your table today.

    trap template

    I use a modified version of the trap template presented in Xanathar’s Guide.

    Trap Name: The best trap names end in “OF DEATH”, but I leave the prefix up to you.
    Challenge Rating: D&D 5e traps don’t have a challenge rating; instead they have a level band, like 1-4, and a degree of severity, like “moderate” or “deadly.” I think this is a mistake. It’s insufficiently granular – even a moderate level 1-4 trap will probably kill a first-level character – plus challenge rating is a tool we already have from monster design! Combining trap recommendations plus my 5e Monster Manual on a business card math, we come out with the formula that a single-character trap should do about 5 damage per CR, while a multi-character trap should do about 3 damage per CR.
    Description: A sentence to sum up the trap.
    Clues: This is where you put the odd detail that will get the characters’ attention. No trap is complete without one! In my case, to increase the usefulness of each trap in the Inspiration app, I’m providing three possible clues per trap. I hope that this will make the same pit trap feel different if encountered again.
    Investigation: What can the characters learn by investigating the trap? I try to include both normal search check results (what the characters learn with a Perception check) and specific, guaranteed-to-succeed actions that will automatically net a clue.
    Trigger: What action causes the trap to go off.
    Effect: What happens when the trap is triggered.
    Countermeasures: What actions the players can take to avoid or disarm the trap. Again, when I can I include both skill checks that will disarm the trap and specific actions that will automatically defeat it.

    Here are two examples:

    Name: 30-foot-deep locking spiked pit trap
    Challenge: 6
    Description: This 30-foot-deep pit has a cover which snaps shut to seal its victim inside. It has wood or metal spikes on the bottom.
    Clues: A trail of faint footprints abruptly end. (DM note: In this case, there is a corpse in the pit.) OR: an arrow is scrawled in chalk on the floor. (DM note: The arrow points to the pit. It was drawn by a denizen who was worried about forgetting where it was and falling in.) OR: The center of the room is dusty; the floor at the edges of the room is clean. (DM note: The clean area is well-traveled and safe to traverse.)
    Investigation: A DC 14 Perception check reveals that foot traffic avoids the pit cover. A DC 14 Investigation check reveals the hidden pit trap. A DC 19 Investigation check not only reveals the pit trap, but discovers a hidden lever, loose brick, or catch which opens the pit lid. A character who taps the floor notices that it sounds hollow.
    Trigger: A creature steps on the trap cover.
    Effect: The trap cover swings open like a trap door, or swings on a pivot. The victim falls into the pit, taking 10 (3d6) falling damage and 11 (2d10) piercing damage from spikes. The spring-loaded (or weighted) cover then swings shut and locks. The cover can be opened with a DC 18 Strength check; from inside, with a DC 16 Dexterity check using thieves tools, assuming there is sufficient light; by breaking the cover, which has AC 20 and 20 hit points; and sometimes by finding a hidden lever which opens the pit.
    Countermeasures: Once the pit is detected, an iron spike or similar object can be wedged under the cover to prevent it from opening, or it can be magically held shut with Arcane Lock. Or you can walk around.

    Name: ice-breather trap
    Challenge: 12
    Description: This trap breathes a blast of cold whenever someone speaks the word “ice”.
    Clues: The room is cold. A ten-foot-tall statue of a barbarian or frost giant dominates the room. The statue appears to be made of ice. (DM note: The ice is magical and does not melt.) OR: The room is cold. There’s a carving of a polar bear on the wall. On the bear’s head is a rune. (DM note: The rune says “ice” in Giant.) OR: The room is cold and contains a marble statue of a fur-clad elf. As you enter the room, a Magic Mouth spell animates the statue’s mouth: “Speak not my name at any cost: a river’s skin in the season of frost.”
    Investigation: A DC 15 Perception check reveals that the mouth is nearly clogged with snowy ice crystals. A spell or other effect that can sense the presence of magic, such as Detect Magic, reveals an aura of evocation magic around the statue.
    Trigger: The trap activates when someone speaks the word “ice” in Common.
    Effect: The mouth releases a 30-foot cone of cold. Each creature in the blast must make a DC 17 Dexterity saving throw, taking 38 (7d10) cold damage on a failed save, or half as much damage on a successful one.
    Countermeasures: Placing an obstacle in front of the mouth deflects the cold blast. A successful Dispel Magic (DC 15) cast on the mouth destroys the trap. Not saying “ice” also works.

    on npc names

    Tuesday, November 19th, 2019

    Some DMs have a gift for coming up with the perfect name on the spot. Others flip through Xanathar’s Guide or another name list. Then there’s me: given a minute to think, I can come up with a plausible fantasy name, but in the heat of the moment I might just blurt out a clunker like “Huckabear“.

    I’m working on a phone app for DMs called 5e Inspiration. It’s a tool for populating your game world with people, locations, maps, monsters, and treasure. Learn more!

    5e Inspiration has a random NPC generator with a massive name list built into it. I’ve been collecting fantasy names for as long as I’ve been playing D&D, and I’ve brainstormed a lot more for the app. Right now my name list has something more than 6000 NPC names – more than twice the number of names in Xanathar’s Guide.

    I’ve vetted all the names in the Inspiration app, which means I’ve said each one aloud to make sure it doesn’t rhyme with something dirty, and I’ve googled it to make sure it’s not a well known trademark or something. (The gold standard for googling a fantasy name: you come up with less than 50,000 hits, and on the first google page is a link to someone’s World of Warcraft character. Then you know you’ve got a keeper.)

    How many half-orc names are there?

    It’s easy for me to tell you that my name list has 6000+ entries: however, it’s quite difficult to count how many names are in any given category. For instance, how many possible half-orc names are there?

    Because Inspiration is an app, I can do more than just create a d100 name chart for each race/gender category. Sure, I categorize names by race and gender, as the Xanathar’s Guide list does – though more than half of my names are nongendered – and also by class. But there are also lots of crossovers and references: on the ranger name list are entries like “roll on the elf name list”.

    Inspiration also includes lots of non-NPC names. The app can be used to generate dungeons, treasure, encounters on the land and sea, neighborhoods, and overland maps, so there are big name lists for magic items, ships, taverns, villages, rare books, various categories of monsters, etc. These lists link with the NPC name lists too.

    The base half-orc name list might have only 2 entries: one “roll on the orc name list”, and one “roll on the human name list”. Drilling down one level to the orc list, we might have 200 entries, of which ten are like “roll on the evil magic item name list”, to get sonorous names like “Ur Kagal” or “Katak”. The evil magic item name list, in turn, might have a few rolls on the pirate ship name list, for entries like “Winter Wolf”, “Howler,” or “roll on the naval ship name list”. So it’s hard to count exactly how many orc names there are. Do I just count the core human and orc names? The 200 evil magic item names, each a twentieth as likely to come up as a core orc name? The 200 pirate ship names, each a hundredth as likely to come up?

    That’s not to mention the possibility of rolling an orc with a barbarian-style name, with all the different name formations that involves: X Y-slayer, X daughter of Y, X Ybane, X Yborn, etc.

    That’s all to say that if you use the app to generate 10 random NPCs per weekly game session for 10 years, you might see a random NPC reappear once, but probably not twice.

    In a further post I’ll talk about how I generate D&D-style fantasy names. Until then, here’s my orc name list:

    Orc Names Roll d20 to select a line. If the line contains 10 names, roll d10 to select the name.

    4: Roll on the Barbarian Names table. (Examples: Turz Son of Jarthak, Axa Wolfbane)

    inspiration: 22 magic item variants

    Monday, November 4th, 2019

    As part of the Inspiration app, I’ve varied treasure by writing up alternate versions of the 350+ SRD magic items. I’ve come up with something like 2000 variants.

    I’m working on a phone app for DMs called 5e Inspiration. It’s a tool for populating your game world with people, locations, maps, monsters, and treasure. Learn more!

    My magic item variants can be divided into 3 types:

  • re-skinned items. The easiest way to mix up magical treasure is to take an existing item and change its form. I’ve talked about this approach here. A potion becomes smelling salts, a necklace’s powers are given to a shield. It’s easy; you can pack flavorful details into its description; it returns a sense of mystery to those players who have memorized the magic items section of the DMG; and it has a light mechanical footprint – it’s unlikely to introduce game-breaking bugs. Re-skins are best when they have logic behind them, but they work pretty well even when the logic is tenuous. A magic-mirror version of a crystal ball is pretty obvious, but you could just as easily reskin a crystal ball as a mug (truth can be found at the bottom of a glass) or a sword (sword of omens, grant me sight beyond sight!) or a pile of herbs (tea leaf divination) or nearly anything else you can kinda-sorta connect to the item’s powers.
  • curses or inconvenient items. The cursed items in the 5e DMG are all interesting, providing tough tradeoffs between power and inconvenience. For instance, the Shield of Missile Attraction makes you a pin cushion for friendly and enemy archery, but it gives you resistance against missile damage. Tough call! I’ve added more items in this vein. I’ve also added items which aren’t cursed, just a little more inconvenient than usual – a spell scroll on a stone tablet, for instance. When a player finds a cursed item, I want them to grumble about it, but strongly consider keeping it.
  • unique items. I’ve added many variant items which have an extra, thematic trait or daily spell. These items often have a unique name. I’ve done this especially often for underwhelming or generic items, which could use the help – but also for some legendary items, just to make them extra memorable.
  • Here are some examples of my magic item variants, for the amulet of proof against detection and location, broom of flying, and holy avenger.

    amulet of proof against detection and location variants (roll 1d6)

    1: a heart-shaped locket scribed with the phrase “thinking of you.” It contains a portrait of the last person to try to magically detect or locate its wearer
    2: a necklace with a pendant that looks like an open eye. When found, the necklace’s power is inactive. If the Thieves Cant slang for “night” is spoken, the eye closes and the power activates. The Thieves Cant word for “day” deactivates the necklace and opens the eye.
    3: a necklace of 10 glass beads: one bead shatters each time it blocks a scrying or divination attempt. The necklace is nonmagical after all the beads are broken
    4: an ostentatious signet ring which once belonged to a princess who disappeared a generation ago
    5: a black hooded cloak
    6: [miscjewelry] bearing the sign of the god of trickery. This item can also be used as a holy symbol by devotees of that god

    In the above examples, I include an item with an extra story power (the locket which identifies the culprit behind divination attempts), and a re-skinned item (the cloak). I didn’t include a cursed version because the Amulet is only useful in a limited number of stories anyway; no need to make it any less attractive. However, since the Amulet is essentially a narrative item, I did include a variant with extra story hooks (the signet ring).

    A note on the holy symbol: My app replaces the tag [miscjewelry] above with a random type of jewelry, so you could potentially find an earring or bracelet of proof against detection.

    broom of flying variants: roll d8

    1: hobby horse with a unicorn head
    2: umbrella: its power operates when it is opened
    3: articulated brass hang glider
    4: winged crown
    5: flying horse statue which is activated by turning a brass key. The key may be hidden nearby or in the possession of a nearby monster
    6: variant: flying wild boar statue, as above
    7: flying shield that the owner surfs on
    8: flying throne

    I like the broom of flying’s power just as it is – I didn’t include any cursed or extra-powerful versions for this item, just reskins. It’s great seeing an armor-clad fighter astride a broom, but even better than that is seeing the entire party flying cross country via a motley collection of different flight methods – the wizard with a fly spell, a guy with boots of levitation who’s being towed by a griffon rider, and other party members on a broom, a hang glider, winged boots, and maybe Baba Yaga’s mortar. Flying is a cool mid-level power and there’s room for a lot of ways to get it.

    holy avenger variants (roll d8)

    1. named Gentle Correction. Once per day, as part of a hit with this weapon, the wielder may cast Command, DC 17, on the target
    2. named Angelis. This sword has a white hilt with an angel-wing crossguard. 1/week, the wielder can cast Conjure Celestial
    3. named Vow of Poverty. The blade resembles stained glass, and depicts knights giving money to the poor. When the wielder draws this weapon, all the coins they are carrying disappear, distributed among the poor of the world
    4. its name Blazing Justice is written in glowing gold on the blade. on a Smite, it does 3d6 extra fire damage and bursts into Continual Flame until sheathed
    5. named Crusader. This sword is sentient (Int Wis and Cha 16), telepathic with its owner, and hates demons. If the sword helps slay a demon of CR 10+, the sword learns how to cast level 1 Cure Wounds 3/day on its owner.
    6. black-bladed sword named Blackbane that exudes an evil aura. Attunable only by blackguard paladins, it does +1d10 necrotic damage on every hit, +3d10 slashing damage to celestials, and doesn’t do extra damage to fiends and undead
    7. named Cloudwalker; decorated with angelic symbols. An attuned wielder can cast Fly, self only, 3/day
    8. named Honor Bright and covered with binding runes and holy symbols: 1/day, if someone touches the weapon and makes a promise, that promise becomes a Geas

    With the holy avenger, I leaned hard into unique variants with extra powers. The holy sword is an integral part of the paladin’s story; a paladin doesn’t want an off-the-rack holy avenger, but a unique sword that was destined for the paladin’s hand. Since it’s a late-game, legendary item, I’m not too worried about slathering on some extra powers.

    A few of these variants, like Crusader, are inspired by historical D&D modules. Others are original. Vow of Poverty is drawn from my home game; as a DM, I’ve had a lot of fun with its associated “curse” (or convenience? depends on the paladin).

    How big does a random generator have to be?

    Monday, October 21st, 2019

    As I’ve mentioned, I’m working on a D&D app that’s a content generator of all kinds: it spits out encounters, NPCs, treasure, and cool locations.

    One makes a random generator by coming up with a bunch of lists, each as large as possible, and crashing them into each other. The bigger each list is, the more depth and reusability your generator has.

    How do you know when you can stop adding to a random table? That’s important to me because I don’t just want to make a random generator that looks cool the first time you use it; I want it to provide useful stuff one, two, ten years from now.

    the birthday paradox

    Maybe you’ve heard this classic math puzzle: in a room of 25 people, what are the odds of at least 2 of them sharing a birthday?

    Unintuitively, even though the odds of any 2 people sharing a birthday is only 1/365, the odds of any shared birthday among 25 people is more than 50%. In a room of 60 people, you’re almost guaranteed (99%) to find at least one shared birthday. That’s weird, right? It’s true because we’re looking for ANY shared birthday. The odds of anyone in the room sharing YOUR birthday are still fairly small.

    Here’s the full explanation.

    You can use this same math to determine how many rolls on a chart you expect before you get a duplicate. A room with 25 people looking for shared birthdays is analogous to rolling 25 times on a chart with 365 entries. On a d20 chart, you can expect to roll a duplicate after only 6 rolls. On a d100 chart, you need only 13 rolls before you’re more likely than not to roll a duplicate. It’s amazing how quickly those duplicates start arriving!

    Of course, a chart isn’t totally useless just because you rolled one duplicate. But at some point the diminishing returns may start seriously reducing the value of the chart.

    Brute-forcing the birthday paradox calculations further, we find the following:
    -If you roll 25 times on a d100 chart, you’re likely to have seen about 22 unique table entries. 3 of your rolls (12%) will have resulted in you seeing a result you’ve already seen.
    -If you roll 50 times on a d100 table, you’re likely to have rolled around 40 unique entries. 10 of your rolls (20%) will have generated recycled results.
    -After 75 rolls, you will have seen 50 of the table results. 25 of your rolls (33%) will be duplicates.
    -After 100 rolls, you will have seen 65 different results and 35 duplicates.

    Thus, in total, after 100 rolls on a d100 table, you will have seen something new 65% of the time, and had the experience of seeing recycled material 35% of the time. To adopt the language of rottentomatoes.com, your experience has been 65% fresh.

    These percentages hold true for any number of items on a table, just so the proportions of entries to rolls is the same; so after your first 50 rolls on a d100 table, or your first 500 rolls on a d1000 table, you can expect your experience to be 80% fresh.

    We have a judgement call to make here, but to me, unless all the entries are highly reusable, a “65% fresh” table feels stale; therefore, if I plan to use a table 100 times over its lifetime, I probably need way more than 100 entries. Let’s choose “80% fresh” as an arbitrary cutoff. At 80% fresh, you see something new on 4 out of every 5 uses of a table. To hit this target, you need to follow this rule of thumb: if you plan to use a random table N times, you need more than (N times 2) table entries.

    This seems like a useful thing to know as a D&D designer, and it gets us most of the way towards knowing how big a dice chart or random generator needs to be to do its job. There’s still one more piece of the equation.

    reusable vs one-use

    When creating a generator, I try to distinguish between reusable and one-use list items.

    Reusable items can come up many times and they don’t make a nuisance of themselves. They’re not obtrusive. They also tend to be rather vague and nonspecific. For example, as part of 5e Inspiration, I’m writing a list of random desert locations. “Dunes of golden sand” is a reusable item: over the course of a long desert journey, you’d expect it to come up frequently. “Sandstorm” is a reusable item too. Although it should come up with less frequency than sand dunes, you don’t begrudge multiple sandstorms over the course of a few desert adventures.

    One-use items are specific enough that they feel unique. They tend to be more interesting than reusable items. Unfortunately, they don’t wear well. One-use items are the mechanism by which a random generator ages: once you have seen a few of them twice, you’re hitting diminishing returns for the whole random generator. One-use examples from my desert encounters list:

  • a sinkhole filled with salt; inside is a salt-caked sailing ship filled with dessicated sailor corpses
  • strange, rusty, ancient towers filled with still-operational chugging machinery that doesn’t appear to do anything. With a DC 14 Intelligence check, you can figure out how to activate the towers, which might be water pumps, oil pumps, or arcane devices that cause all damage spells cast within a mile to do maximum damage
  • rainbow sand dunes: if a beast is encountered here, it may also be rainbow colored
  • As a player or DM, I’d roll my eyes if I saw any of these twice.

    A generator with no one-use items is evergreen, but rather dull. A generator with all one-use items, according to the birthday paradox math we did above, needs to be big enough that most of its entries will never be rolled.

    Based on your mix of one-use items in your generator, and how many times you want it to be used, you can determine how much work you need to put into coming up with new entries.

    Most of the random tables I write are a mix of fairly generic, multi-use results and rare, interesting, one-use results. To figure out how that impacts a table’s “freshness” calculation, ignore the number of die rolls that are likely to return a generic, multi-use result. For instance: If you’re rolling 100 times on a d100 chart, but half of the chart’s results are generic and reusable, treat it as if you are rolling only 50 times on the table. Thus, for 100 rolls, your half-generic d100 table is 80% fresh.

    the freshness calculator

    Here’s a “freshness” calculator you can use to figure out how big your random table needs to be to meet your desired level of interestingness. This calculator uses brute force, simulating results 1000 or so times.

    what about multi-table random results?

    Not all random generators are a single die-roll chart. Many are in the format “roll once on table A, once on table B, etc”. For instance, a tavern name generator could be a single d100 chart where you get a complete name like “The Golden Goose” if you roll a 36, but it’s more likely to be 2 d20 charts, where you roll the “The Golden” on table 1 and “Goose” on table 2. How do you evaluate the freshness of these grouped tables?

    I think that for multiple tables, you evaluate each of the tables separately, and then you use the worst result. People are really good at spotting patterns. Once the party has been to The Golden Goose, The Red Goose, and The Unnamed Goose taverns, you just can’t have any more goose tavern names. It doesn’t matter that you never rolled a duplicate on table 1. The repetition on table 2 makes the whole game world feel more creaky and procedural.

    how do 5e tables fare?

    Now, let’s use this procedure to evaluate a few of the random tables that come in the 5e Dungeon Masters Guide.

    5e has been around since 2014. Assuming you’ve run a weekly game for the past 5 years, how “fresh” are the following tables?

    The official 5e magic item properties tables. There are 4 tables, ranging from d8 to d20, with 60 properties total. The instructions are to “roll on as many as you like.” Let’s assume you’ve rolled on only one table per magic item, and only for major magic items: say, one die roll every two sessions. By now, you’ve rolled about 120 times, and there’s only 60 entries, so you’ve hit a lot of dupes (43% fresh). Chances are you’ve given up on these charts already. I bet you rolled for magic item properties 10 or 15 times, hit a few duplicates, used the charts as inspiration lists a few more times, and then stoped altogether. That’s roughly what I’ve done, anyway.

    How many random magic item characteristics would you need to provide, say, an “80% fresh” experience for 125 rolls over the course of 5 years? Plugging in numbers into the freshness calculator, it seems that 300 characteristics would just about do it. That’s a far cry from the 60 that are provided.

    The NPC traits charts. There’s a d20 chart for NPC appearance. How many of the items are reusable and how many are one-shot? I’d say it’s maybe 50/50, with “flamboyant clothes” and “bald” being reusable, and “nervous eye twitch” and “missing fingers” being unique. If I ran into 2 NPCs who were missing fingers, I’d suspect they were the same doppelgänger.

    If you’ve used this chart to make just 1 NPC per week for the last 5 years, you have 12 folks running around your campaign world with missing fingers. Clearly this table is not big enough. To provide specific and fresh results for 250 NPCS over 5 years, you probably want a d500 table at least.

    the DMG vs the Inspiration app

    OK, it’s not completely fair to judge the DMG charts this way. They’re clearly meant to provide inspiration – to teach you how to customize your magic items and NPCs. After rolling on the charts for a few sessions, you’re supposed to be able to do your own homework before each session – spread your creative wings and fly!

    Well, that’s bully for the DMG. I, on the other hand, am not here to help anyone learn to fly. I’m here to do your homework for you! The Inspiration app currently has about 500 NPC characteristics, many of them evergreen, and about 2000 magic item variants. It should be able to provide you dungeon mastering freshness for the next 10 years at least.

    Next week, let’s look at some magic item variants from the app.
