It's a fantasy role-playing game.

DM: You are Mollymauk Tealeaf, a tiefling blood hunter . You are the member of the famous group of adventurers. Previously, Fjord is quickly rendered unconscious, but uses Relentless Endurance to pop back up to one hit point. He is almost immediately hit into unconsciousness again.
DM: 13's fine, you maintain concentration. The other one that's right next to Beau is going to attempt to also throw its harpoon at you, since it saw that you were the source of this. They're trying to break the spell.
Player: I'm going to go ahead and cast some bullshit on that.
DM: You were holding an attack. You'll have to say that—
Player: This is a reaction. I'm doing a Blood Maledict. The next two attacks are disadvantage.
DM: You're amplifying it?
Player: Yeah.
DM: Okay, go for it. So roll the damage, that's disadvantage on that.
Player: One point of damage.
DM: That's a 17 to hit. What's your armor class?
