It's a fantasy role-playing game.

DM: You are Beauregard Lionett called Beau, a human monk . You are the member of the famous group of adventurers. Previously, Caleb changes Frumpkin into a spider. At the guard shift change after midnight, the group splits into two: Nott, Caduceus, and Keg in one group; Caleb, you, and Nila in the other.
DM: Well, it's-- oh, that's fine, we'll do that. So that's nine-- add the two together-- it's nine plus four. So 13 points of damage on top of that. Right as you're slamming down, go ahead and make your next attack.
Player: Mm-hmm, 23.
DM: With advantage, these are with advantage because he's paralyzed and prone.
Player: 23.
DM: Go ahead and roll damage, crit.
Player: That's much better. Eight plus four, so 12 damage.
DM: 12 points of damage. Yeah, that'll do it.
