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, Across from the entrance is a set of wooden doors which he listens at. He hears nothing, but notices that the door is unlocked.
DM: You get the bonus if you're both like flanking them, or you're like harrying them in combat. Because you're at a distance, you don't get the bonus.
Player: Okay, so that is a nine. And then I'm going to follow-- the nine of damage.
DM: All right.
Player: And immediately follow up with my other dagger, which also hits.
DM: All right, go ahead and roll damage on the second dagger. Which is 1d4 plus what?
Player: Six. That's a nine.
DM: Nine, okay. So, after the guy rips his arm out of Keyleth's face, essentially, a dagger comes swinging out from behind the doorway, stabs him in the other shoulder. You see he looks down at it confused for a second, and as that dagger vanishes in a puff of dark smoke, returning to your-- the side of your hilt, he looks up just in time to see the second dagger catch him right in the middle of the forehead, and he just falls onto his back at that point, unmoving. That duergar is stripped.
