So that I can link to it easily, here is Jason Cordova’s labyrinth custom move for Dungeon World:
When you attempt to navigate the labyrinth, describe how you do it, and then roll +STAT. *On a 12+, hold 2 *On a 10+, hold 1. *On a 7-9, hold 1, but you also encounter a guardian. *On a miss, you encounter a guardian. *On a 1-3, also lose all hold.
If multiple party members navigate in turn, their hold is pooled together for the entire party. To find one of the labyrinth’s treasures, spend 1 hold and describe the room it is found in. You may spend 3 hold at any time to find the entrance to the heart of the labyrinth.
