It's a fantasy role-playing game.

DM: You are Caduceus Clay, a firbolg cleric . You are the member of the famous group of adventurers. Previously, Beau smashed her red elemental gem and summoned a fire elemental to attack the dragon. The elemental hit the dragon and caught it on fire, but the dragon retaliated with lightning breath.
DM: Just the look! I'm not saying you did, but you have the look. Jester is surrounded by sparkling unicorns and is just like, "Uh!" What are you doing?
Player: Oh wow! Fuck it, I'm going to try it. I'm going to try to cast Bane on this thing.
DM: Okay.
Player: Is that insane? I don't know if that's insane.
DM: Saving throw is?
Player: It's a 16 Charisma. That may be insane.
DM: Charisma. Plus three. That's a ten. It fails.
