It's a fantasy role-playing game.

DM: You are Vax Vax'ildan, a half-elf rogue . You are the member of the famous group of adventurers. Previously, A scuffle ensues as they chase down a necromancer, a number of cultists, and some creatures from the Shadowfell. During the fray, Scanlan gets Sprigg back on his feet, and Keyleth kill a couple of the cultists with a Firestorm.
DM: So the second dagger, you shiv him in the side and he (groans) goes to spin with the heavy crossbow and try and pull away, and as soon as the poison through him he goes, (gurgles) and you can see blood vomit down the front of his chest, his eyes roll back and he twinges and falls to the ground.
Player: And there's another guy there who can see me, right?
DM: Yeah, and he's hidden, but he's like (scared, heavy breathing).
Player: Whisper.
DM: Okay, he's trying to see that you're not being seen.
Player: That is 31. Yeah, okay. So that is two plus eight is ten, plus psychic damage. 18. I'm going to bamf there with Whisper.
DM: Okay. All righty. You hit him and you stand there. You're right in front of him now. All righty. That ends your go. As you appear over on the other side, you realize that over in the clearing there, there is another one of the robed figures, this one clutching a long, black, smooth staff that crooks over in the front that looks like a hand holding an eye.
