It's a fantasy role-playing game.

DM: You are Beauregard Lionett called Beau, a human monk . You are the member of the famous group of adventurers. Previously, Nott and Jester, to almost universal horror, break out Fluffernutter, with Jester throwing the barrel in the air towards the heads, but Nott's explosive bolt misses and the barrel splashes into the water. Just prior to Yasha's turns, Caduceus casts Path to the Grave on the hydra, making it vulnerable to everything for double damage.
DM: Well, here-- you resisted all of the damage from the arrow entirely. That's pretty slick. Yeah, it doesn't even catch you. No poison. You manage to stop it in place. The poison doesn't even hit your system.
Player: I'm going to-- I'm going to not spend the ki point.
DM: Watching you reach behind and catch the arrow and stop it from going there, and the second one just manages to dodge past you. (growling) It's going to go ahead and--
Player: I look at him and I take the arrow and go--
DM: That's when you take the 2d6.
Player: No! Resistance! (spitting)
DM: Spitting it out on the side, your lips and tongue go a little numb. All right, that ends its go. Fjord, you're up and then Caleb you're on deck.
