Surprise attack!
In combat, the bard is singing and playing his music while the others fight.
DM: Okay, it’s the rogue’s turn. No one has noticed him yet.
Me: I hide in the bushes because I’m tiny and those things are going to eat me.
Bard: I incorporate the rogue being a coward into my song.
Me: Since the buffs last for a few turns after he stops playing anyways, and he doesn’t see me right now, can I use the bonuses to sneak attack our bard with my sap?
DM: … …. … you know what? Sure. Whatever. You guys are really bad at this teamwork thing.
