Because there’s not enough magic swords, right? Here’s a semi-cursed magic sword I made up for last week’s game.
It’s a scimitar that appears to be made out of pure gold, with a fanged mouth at the end of the hilt. Its name is “Feed me gold!”
The sword can be in two states: hungry or sated. When it’s first discovered, it’s hungry.
Hungry: The sword periodically roars “Feed me gold!” or “Give me gold or I will smite you all!” in an ear-splitting Yosemite Sam voice (audible for half a mile). It takes especial care to yell when enemies are nearby or when its owners are sneaking. The hungry sword is heavy and clumsy in combat (-1). Once per day, the sword can cast Knock. It does so only to thwart its owner or to change owners (for instance, by unlocking a door between it and a thief).
The sword requires 1 GP per day to be sated.
Sated: The sword acts as a +1 intelligent scimitar (it has Int, Wis, and Cha of 8). It will speak at a reasonable volume. It can cast Knock once a day at its owner’s request. When it casts Knock, it yells, “Gold opens all doors!”
Here’s how I introduced the sword: lodged in the back of a dark cave, shouting imperiously for gold in a scary monster voice, and bossing around the local peasants.
My group hates the sword. One character wants to throw it in the river. Others are like, “Well, it’s a jerk, but it is a +1 sword. We should probably keep it.” It galls them to pay an object; they’d probably be much happier if they’d bought it outright.
It’s funny because the group also hired some mercenaries in the same session, for exactly the same price, 1 GP/day. To be fair, a henchman is better because when they die you can take back their salary.
