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, There, they find a cave filled with magical darkness. Keyleth shifts into an earth elemental to scout the cave, finding that it contains a strange planar rift and a group of grick.
DM: First thing you notice one of them is giving off an awful stench. The smell you smelled when you first entered the cavern is now so strong that it's nearly overpowering.
Player: Is there one specifically?
DM: It's hard to find a source to it. However, you are taking a claw strike from each of them.
Player: Oh, good.
DM: That is going to be a six. That misses. That is a 19?
Player: Yeah.
DM: Hits. 18?
Player: Yeah.
DM: And then 20.
Player: Hell yeah.
DM: All right. So, three claw strikes. You take seven points of slashing damage, another seven points of slashing damage, and then a ten, so that's a total of 24 points of slashing damage.
Player: Okay. (grunts)
DM: As all these horribly-muddied and half-rotted claws start sinking past the armor into your flesh, the back of your neck. One catches you in the side. And it all happens so fast, you feel like you're almost spun around by the sheer force of the impact. I need you to make three constitution saving throws.
