It's a fantasy role-playing game.

DM: You are Vex Vex'ahlia, a half-elf ranger . 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 you.
DM: Okay. So as you take your shot, (gunshot) it ricochets off the armor. The dragon's starting to look a little rough. You can see bits of the blood beginning to seep from the inside of its scales. It's starting to look a little harsher and harsher. It's still standing up pretty well, but you can see, it's starting to get a little more battle-worn. That ends Percy's turn. Vex, you're up.
Player: Me?
DM: Yes.
Player: Okay, I'm going to move Trinket away.
DM: Trinket stands up, and Trinket's going to move back this way.
Player: Yeah, and then hide behind that outcropping thing. Yeah.
DM: Okay. As he moves away, the dragon uses his reaction. It's going to be a bite attack on him, actually.
