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, She tests the roots of the cursed tree for any illusory magic, but it is solid and real. Grog attempts to level up the Titanstone Knuckles by destroying the kitchen, much to Scanlan's consternation.
DM: For a legendary resistance, it does. Which is why if you can burn through those early, then they're a little more vulnerable.
Player: And just because nothing else seems to be happening, I'm just gonna burn my Action Surge and just keep plowing into him for two more shots.
DM: All right. How much damage did the first one do?
Player: That did 20 points of damage.
DM: Nice! (gunshot sound)
Player: Taking another shot, that's 29.
DM: Hits.
Player: That's 28 points of damage.
DM: Three hits. Go ahead and roll the other two damage, now.
Player: Hm?
DM: So you hit with all three, so.
Player: No, I've been doing damage.
DM: Oh, those were the damage.
Player: Yeah.
DM: Oh, I'm sorry.
Player: Sorry. That's 20 points of damage and 28 points of damage. 22... wait. 20 points of damage on the first attack.
DM: Yeah.
Player: Attack I just did was 28 points of damage.
DM: 28, sorry, all right, and then the third one.
Player: And then the third one.
DM: Roll to hit.
Player: That hits, that's a 31.
DM: All righty.
