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, They are greeted by the voice of the rakshasa, who calls himself Hotis and offers them a new contract to replace their current one. Thorbir senses Hotis' insincerity and refuses the deal.
DM: Yeah. Even though you're invisible, he looked right at you and cast the spell. You gather that there's something about him that can see through invisibility. With that, he's going to move in that direction. And at the end of that, that brings us to Vax.
Player: All right. Well, I earlier rolled a 32 on stealth, but I don't know if that means shit right now, but I'm clicking my Boots of Haste and moving along the wall.
DM: Along the wall here?
Player: No. I'm going to stay put. I'm going to attack him. I'm going to throw-- dagger, dagger, dagger-- through the air. (flying blades) From the shadows. I have no idea. He might be able to see me like the Predator.
DM: Okay. Go for it.
Player: He already moved, right? So I don't get advantage for Assassinate, but we'll see if I get sneak attack damage. That's a three, so that's shit. That's a nine-- 15.
DM: 15? Misses.
