Critical Role fully unveils its new D&D house rules, and they’re brutal

It’s been established early on in Campaign 4 that Critical Role isn’t afraid to shake up the rules of combat to enhance narrative flavor. In episode 8, “Fanged Revenge,” Dungeon Master Brennan Lee Mulligan introduced new homebrew rules called Desperate Measures. Mulligan explained that Desperate Measures occur after a player is bloodied — meaning they are at half hit points (HP) or lower.
