It's a fantasy role-playing game.

DM: You are Vex Vex'ahlia, a half-elf ranger . You are the member of the famous group of adventurers. Previously, He then inspires you with his harmonica. Keyleth, under the thrall of the ghost, attacks Scanlan with her staff and hits despite the bard's Cutting Words.
DM: All three hit? All right, so no attacks of opportunity against Trinket. Roll damage, and everyone takes that damage.
Player: I don't know what to roll for cannonball damage because I've never actually gotten to hit.
DM: Oh, I know. I have this. It's 2d6 plus four.
Player: Okay. For each person?
DM: Yep.
Player: Oh, okay, so ten for Keyleth.
DM: Ten points of bludgeoning damage.
