It's a fantasy role-playing game.

DM: You are Vax Vax'ildan, a half-elf rogue . You are the member of the famous group of adventurers. Previously, you puts his wings out and flies underneath Vorugal in stealth, throwing Whisper at him. He hits and blinks up with the blade, now on the dragon.
DM: All right, before you get there, he's now (roars). The angry scream. Vorugal's head swoops around underneath and directly into your eyes as you dart away with the blade. He spins in place and bites at you as you're trying to pull away.
Player: I have advantage on dexterity saving throws.
DM: Okay. This is a bite attack, so it doesn't matter. So that is a 26?
Player: That hits.
DM: All right. So you take 22 points of piercing damage.
Player: Okay. Can I Uncanny Dodge this? Is this melee?
DM: Yeah, it's a melee attack, so you can do that. Plus 14 points of cold damage.
