It's a fantasy role-playing game.

DM: You are Grog Strongjaw, a goliath barbarian . You are the member of the famous group of adventurers. Previously, Vax dashes past Greenbeard towards Kevdak, one of the herd members outside the arena attempting to swipe at the rogue but only catching feathers from the Deathwalker's Ward, and attacks the paralyzed Thunderlord with both daggers in hand. The blades strike true, Vax sinking the weapons up to the hilt into the flesh of the goliath, and the rogue flees the arena, but not before he leaves some parting words for Kevdak.
DM: Seven plus eight, 15, reduced to half, that's seven. So I'll give you the direct amounts here. So this is with the reduction. So that's seven points of slashing damage. Another seven.
Player: Okay.
DM: Another seven.
Player: Okay.
DM: Here we go. That's a nine.
Player: Okay.
DM: Not that great. That's a six.
Player: Okay.
DM: And then now the crit.
