It's a fantasy role-playing game.

DM: You are Nott the Brave, a goblin rogue . You are the member of the famous group of adventurers. Previously, The rest of the party creeps closer and the guards are alerted by Keg's lack of stealth. Meanwhile, Shakäste has gotten both hands free and removed his gag, and casts Spiritual Weapon, which misses, but he is able to pick the lock of his cage and step out.
DM: Protto, who has kept you at bay and can see the space between the bars, takes out his crossbow. The one that he can see best at this moment is Nott. He's going to take a shot at Nott. That's going to be a 17 plus four?
Player: Oh yeah, that hits. For sure.
DM: Plus six to hit. That hits. This is a longbow, not a crossbow. My apologies. That's two plus four. You take six points of piercing damage.
Player: Okay. Yes, fine.
DM: Then he's going to dart around the corner.
Player: Oh wait, I can take my little-- my reaction, can't I?
DM: Yes, you can.
Player: What is that thing called? Uncanny Dodge? Uncanny Dodge! I'll reduce that to three.
DM: There you go, so three damage to you. That's going to end Protto's go, as he darts around the corner. Beau, you're up.
