It's a fantasy role-playing game.

DM: You are Vex Vex'ahlia, a half-elf ranger . You are the member of the famous group of adventurers. Previously, She  Dimension Door'ed her way into the ritual room, which  Vox Machina  followed over the wall. She seemed to complete the ritual, creating this small, vacuous, spinning black sphere that is locked in place.
DM: Eight! Yeah! All right. First and foremost, Vex, you're up with the initiative on this. You go ahead and you bring your holy arrow and you release it.
Player: Is it a surprise attack?
DM: Technically, no, it knew you were there, it was very aware of everyone's position. And was essentially after being forced out of his body at the moment preparing itself for some sort of assault, so not a surprise round, unfortunately. So go ahead and make your attacks with your arrows, if you'd like.
Player: Yes! 28 and 27.
DM: Both of those hit.
Player: Awesome. Okay. These two... balls. So 15, 16, 17, plus holy damage?
DM: I'll consider that, do 1d4 radiant damage to it. In addition to that, so 17 plus--
Player: 17 plus four is 21.
DM: 21 for the first one.
Player: And then ten for the second.
DM: All right. So--
Player: And then I Hunter's Mark him.
DM: All righty.
Player: I didn't say I Hunter's Marked him at the beginning-- I'm explaining this to you guys, because I'd already said I shot at him.
DM: You did.
Player: So I was being honest. I'm looking at the chat room, because I know they're going to tell me I forgot my damn Hunter's Mark.
DM: That's okay. All right. You pull back and release the first arrow. As it goes and hits, you can see the smoke itself is obscuring its place and keeping it hard to hit, but you still strike true, the arrow striking into its form. And there's a flash of radiant energy as it hits, and you see the creature takes from the impact and stares down at its chest. As it looks up, its face turning towards you, and it is this formless humanoid body, but the face itself does pinch into this elongated crow skull--
