It's a fantasy role-playing game.

DM: You are Scanlan Shorthalt, a gnome bard . You are the member of the famous group of adventurers. Previously, They  looked above and  they  saw what looked like the entrance to a cavern where at least the dragon seems to fly in and out of. It's a ways up the mountain, and there's a smaller cavern towards the base of the mountain.
DM: That is true. You leveled up after the last one. So with this short rest I will say go ahead and roll an additional-- for a bard I think it is a d8, correct?
Player: I don't know.
DM: What's your hit dice number?
Player: d8.
DM: And what's your constitution?
Player: 15. Plus two.
DM: All right, so go ahead and roll a d8 plus two to it
Player: Four.
DM: All right, so you add four hit points to your total hit point maximum. Welcome to level 11, Scanlan. (cheering and singing Super Mario victory ditty) You also get access to your first 6th-level spell.
