It's a fantasy role-playing game.

DM: You are Percival de Rolo, a human gunslinger . You are the member of the famous group of adventurers. Previously, Grog then takes the first bead of divinity -- the one from Ioun-- smashes it on the Anvil, and folds the powdered remains into the first ingot. With aid from Keyleth and Scanlan in the form of spells and inspiration, he does the same with the bead from Pelor, but has trouble with the one from the Raven Queen.
DM: It is currently dangling off the side, along with other series of tools: tongs and other smaller blacksmithing accoutrements.
Player: I'm going to run in that direction.
DM: Okay. Five, ten, 15, 20. Another step, and you're starting to hit the molten metal and rock.
Player: Molten metal and rock? I can't jump that, can I?
DM: You can try, yeah. Make an athletics check.
Player: Not an acrobatics check, I take it?
DM: Not for the leap.
Player: But there are chains that I can reach there?
DM: If you're leaping towards the chains, you can attempt to grab it, yeah.
Player: Well, I'm going to attempt to grab the hammer.
DM: Okay. Are you using it to swing, or are you just trying to grab and hold on?
Player: If it's available for a swing, I'll try for a swing.
DM: Okay, I'll give you advantage if you're going for the chain, then, as you're swinging across it. Go for it.
Player: Roll with advantage? Athletics?
DM: Athletics.
