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, Vax walks along the wall, unable to attack from a distance, and heads to Scanlan. Grog directs his attention to the remaining horror and smashes it twice with the warhammer.
DM: I'll say yeah, you can see him all right. You can move over there and get a better view a little bit. Just around this corner, off the table.
Player: And I'm going to Hunter's Mark him.
DM: Hunter's Mark him?
Player: And then I'm going to shoot him.
DM: Okay, go for it.
Player: Oh gosh, I'm just so nervous about picking the 20. No. 19?
DM: 19? The arrow hits the armor and shatters across the side.
