Whenever HP or healing are brought up in D&D conversations, they tend to dominate the rest of the discussion, and no consensus is reached. I think the issue is confused because “healing” really means three different things:
per-round: How much healing should you get during a fight? Are you limited to a cure spell or two, or does everyone have second winds, potions, and wands of Cure Light Wounds?
per-hour: How much healing should you get between fights? Does the damage from the last fight significantly drain HP and healing resources, or is each battle a self-contained tactical challenge?
per-day: How much healing should you get overnight? If you’re really beat up, is it important to determine if you rest a day or rest a week to heal fully?
I’ll misuse my Mearls software to make a quick poll:
I’d love to know how you use each of these three elements in your game. Do you (or your DM) limit access to potions, or use easy fights to drain daily resources, or make the characters start a day of adventuring low on HP?
