It's a fantasy role-playing game.

DM: You are Keyleth, a half-elf druid . You are the member of the famous group of adventurers. Previously, The frost worm bites you, who casts Blight as payback and heals herself. Vax asks Pike for healing, then hits the visible worm.
DM: It's going to turn around. You can see now, its tail emerges, and it's going to arc up and try and bite and slam in your direction with both sides of its body at once. This tail does not have a stinger on it, but it is still a giant bludgeoning implement. First attack is going to be a 19 to hit?
Player: Yeah.
DM: Next one is going to be a 16 to hit.
Player: No.
DM: All right, so the tail slams on the ground next to you, estimating your position and failing and just hitting the rocks that you had slid down. However, it does bite down with its open, icy jaws. You take 17 points of piercing damage, as well as an additional six points of cold damage.
Player: Bringing it to a total of 22?
DM: 22, yeah.
