It's a fantasy role-playing game.

DM: You are Nott the Brave, a goblin rogue . You are the member of the famous group of adventurers. Previously, You began to look throughout the room. You found a sword across the upper ceiling, an ornamental blade of some kind.
DM: That's for melee stuff. This is it being covered, and you're aiming through these tiny holes as you're firing at it.
Player: It has half-cover or something?
DM: Well essentially. Yeah, I'd say at this close it has three-quarters cover. It's a plus five to its AC. What did you roll?
Player: The first roll was 22.
DM: Yeah, it hits. We'll say it hits, because you're right up against it with a crossbow. You're not having to aim in with it. You're (bolt flying). Roll the damage.
Player: Six points of damage.
DM: Six is enough. The pots aren't very strong; it's just hard to touch (shattering). That will-o'-wisp manages to discorporate next to you.
Player: Eight is Enough. I'll skitter around towards the candelabra over there, and as I go I'll (cocks crossbow) and fire another shot at the other pot.
DM: Okay, that one you do have disadvantage on as you're farther away from it.
Player: 19.
DM: 19 still hits. Go ahead and roll damage.
