We have all female characters in my group and they’re all cursed to have growing titties during combat. At the start of each conflict, I tell them all that they’re sitting in A cups right now, their armor fits fine, they can run and jump and swing weapons and cast spells with zero hinderance, but as the battle progresses, their tits grow and grow and become more difficult to deal with. Their movement speed drops, a lot of actions require exceptionally high rolls to succeed, attacking and evading become more difficult. There’s a bonus to anything Charisma based though, because ya know, big ol’ titties. Here’s the thing though, if the battle takes too long, and should their tits get too big, then they lose that Charisma bonus when their tits are so massive that they become grotesque. At some point they’ll become totally immobile, just jiggly jubbly sitting ducks that any Goblin or slime thing could pop off on. We really like this big titty curse because it adds a ticking clock element to all interactions.
