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, Percival shoots Clarota in the head, releasing Scanlan, who had been grappled by the turncoat. As the remaining illithids take heavy damage, the two of them Plane Shift out of the room in self-preservation.
DM: You know what? He is grappling and he is right in the way, I'll go ahead and give you advantage on that attack. Roll again.
Player: Yes! So I just roll again?
DM: Roll again. Take whatever it is.
Player: 22!
DM: 22 will hit, okay. Because it is a stationary position, completely engulfing, and you have such a great view from above.
Player: Right? 11 points of damage?
DM: Okay. Did you roll your Hunter's Mark damage?
Player: No, I did not.
DM: Don't forget Hunter's Mark.
