It's a fantasy role-playing game.

DM: You are Vax Vax'ildan, a half-elf rogue . You are the member of the famous group of adventurers. Previously, Many of the townsfolk gathered at that square were immediately killed. The party, as well as a few other straggling survivors, ran away as both the gargantuan black and green dragons began to chase  them  down.
DM: Yeah, it can't see right now. Currently it's obscured. Oh, hold on! But it has blindsight 60 feet, so it has no effect on him, unfortunately. So as it stops in the air, it still manages to use its sense of smell and the general atmospheric ability to sense what's around it. It seem to move its head and search--
Player: Can I attack right now? I was holding my attack.
DM: You can. Now, what's the range on your daggers?
Player: 60, because I'm Sharpshooter.
DM: 30, 40, 50, 60-- it's just at the cusp. Like just barely cusp, but yeah, you can get your attack.
Player: So I'm going before him, and it's a surprise attack because I'm hidden and I'm going first--
DM: Yes, you're essentially interrupting his attack because the moment he came into range--
Player: So it's an advantage and it is an automatic crit?
DM: It's not a automatic crit, it's not surprised.
Player: It's not surprised?
DM: No, it know you guys are there.
Player: Even hiding behind a tree? All right.
DM: A surprise generally means that it has absolutely no idea that you are there or there's any sort of threat from you.
Player: 24.
DM: 24 hits.
Player: All right. And then the second dagger I throw-- I can only throw a second one-- is also a 24.
DM: Both hit.
Player: So the first one is double dice, so eight plus-- 14, 15, 18, 23, 25. Double dice is 50 plus seven is-- Yeah, 57 for the first.
DM: Ooh, nice.
Player: And the second one goes bink. That is a ten.
DM: Ten, all right. 57 points of damage, that's-- Is that straight-up dice rolls? That's crazy.
Player: That's Sneak Attack, I've gone up a level to 13--
DM: Right, so it's a d6 or 7d6.
Player: 7d6-- Oh, wait.
DM: It's not doubled, though.
Player: Sorry, sorry, sorry. 25 plus seven is 32. Sorry, 32.
DM: 32, there you go, I was like, that's really high for a non-crit.
Player: The second one was ten. 32, ten.
DM: So 42 points of damage. Still not shabby by any means. Gotcha, as you chuck both daggers in the direction where you can see as it's now at the very bottom of the fog cloud. You have enough visual to strike towards it without missing and both daggers sink into the bottom of the creature. One of them you know was a nice, impactful wounding for any other creature, but it doesn't seem to have taken much issue with the impact of the blade. Appear at your side again. That ends your reaction. Now Vorugal is going to go. Looking at the area of most density--
