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 wants to destroy the orbs but Vex and Scanlan caution against it, not wanting to alert Thordak. Vex checks out the mast.
DM: Eventually you make your way back to Scanlan's Magnificent Mansion and gather the rest of the party. Percy, Kima, Keyleth and Vax are all there, resting and eagerly awaiting your return.
Player: I've got to try and fix my guns.
DM: Okay, make some tinkering checks.
Player: Is this a misfire check or a tinkering check, since I'm not in combat?
DM: These are tinkering checks.
Player: Okay, so it's proficiency bonus, dex roll. Ooh, 28!
DM: That's your Animus?
Player: Yep, that's fine.
DM: I believe Bad News was also?
Player: Yup. 26.
DM: 26 is fine. You manage to get Bad News functioning again in the workshop below. And Retort was okay, right?
