It's a fantasy role-playing game.

DM: You are Fjord, a half-orc warlock . You are the member of the famous group of adventurers. Previously, He warns the rest of the Mighty Nein as combat continues. A crew member unfurls the sail, which is plain, attempting to escape the area.
DM: At that guy? You can look and see now he is not the Enforcer that went below deck previously. He's dressed similarly, but now that you get a better look at this view in the light, he's somebody else. There is still one person down in the ship.
Player: (quietly) Awesome, great, good stuff. (louder) That's a 20.
DM: That hits.
Player: 11.
DM: That hits. Roll damage.
Player: Oh, nice, okay.
DM: Yeah, he has leather armor. His AC is 11; he's pretty easy to hit.
Player: 11 points of damage on the first one and ten points of damage on the second, so 22 total.
DM: Ooh, that'll do it. Both blasts take him down. The attrition is not working well in his favor.
