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,   The party then, in trying to locate Grog's position, found their way, delving past the lava-fall of the obsidian rock duergar-Underdark, deeper in, discovering this cursed pit of undeath, bone shards, and glass. Upon traversing it they encountered one of these abominations that  they've  seen traces of left before—this weird, partial-elven, partial-tentacle monstrosity that slashed through the party, nearly killed Trinket, but was defeated by  Vox Machina .
  They  managed to make  their  way across this bone field and discover what appears to be a camp across a number of pillars in the distance.
DM: Okay, so you whip around, he's there in your face, go ahead and make-- You're using your action surge to fire two additional times, you said?
Player: Yeah.
DM: Okay, wow, four rounds. Go for an attack.
Player: First attack with Pepperbox is 13?
DM: 13? Unfortunately misses. Form shifts (whooshing sounds), and you can feel the psychic energy of its oppressive mental force, causing your hand to miss its aim with each pull of the trigger.
Player: All right fire shot for 19.
DM: 19 does hit.
