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, you then takes the first bead of divinity -- the one from Ioun-- smashes it on the Anvil, and folds the powdered remains into the first ingot. With aid from Keyleth and Scanlan in the form of spells and inspiration, he does the same with the bead from Pelor, but has trouble with the one from the Raven Queen.
DM: Yeah, you're fine. So you maintain concentration on your form. Perfect. That finishes Keyleth's turn. Grog, what are you doing?
Player: Yeah. It's hammer time. I'm going to run down here-- five, ten, 15-- right there, to this side.
DM: Perfect, you can get up right against there. The elemental gets one swing at you as you go out of its range. That is a three plus seven. Ten. It hits your back and it's like, ooh. It's kind of cool.
Player: And I'll take both of my attacks at the giant death-bringer. Just reckless, not great weapon master. Hoping for a crit, which was not it. 31.
DM: Hits.
Player: Great. That's better. 32.
DM: Hits. These are both with the minus five?
Player: No, not great weapon master. Just reckless. Six, 22 for the first one.
DM: Okay.
