A drinking game I came up with, though I’m sure that people have done this before; feel free to check my other posts on the Dungeon Map!
These are all optional; most are controllable by the character, and most are ‘mistakes’ a character can make. Write up your own list before you start playing so that it is clear which ones you have decided to use.
A player drinks when their character:
Casts Cure Light Wounds, Lay On Hands, Uses Sneak Attack, Casts Magic Missile, Goes Into and Comes Out of a Barbarian Rage, or uses some other suitable class feature agreed upon during character creation.
Drinks a Potion
Gains a Negative Status Effect
Dies (probably a couple drinks here)
Is Hit by a Trap
Rolls a 1 on an Attack
Drinks (in character)
The DM Drinks When:
A Monster Dies (think about this one, it happens a lot)
A Character Rolls a 20
A Character Finds a Magic Item
A Character Disables a Trap
An NPC Drinks (in character)
A Character Spots an Anachronism
Everyone Drinks When:
A Nerdy Media Reference is Made (Leroy Jenkins, Double Rainbow, Attacking the Darkness, etc)
Mountain Dew or Doritos are Mentioned Aloud
