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, A breath of frost kills one of the giants before it is able to do much. Percy's engineering talent makes a showing, between a hand grenade and one of the exploding arrows he made for Vex.
DM: You could get there. You will have to make-- actually, no, you can move through there without an issue.
Player: Also, I have darkvision up to 60 feet.
DM: You rush up towards the dragon.
Player: I'd like to take my Firebrand Warhammer and activate it. Ignite it.
DM: As a bonus action. Well, it's already been ignited, you've had it flaming this whole time.
Player: Oh, beautiful, yeah. It's like a torch, which means I can see even better. I'd like to go into a frenzied rage and start swinging away.
DM: All right, so three attacks on the big old dragon.
Player: 19.
DM: 19 does hit.
Player: Beautiful. 25.
DM: Does hit.
Player: And 23.
DM: All three hit. Go ahead and roll damage.
