It's a fantasy role-playing game.

DM: You are Keyleth, a half-elf druid . You are the member of the famous group of adventurers. Previously, Judging by the weather, they have arrived somewhere in Exandria. As Vox Machina comes within range of the base of the tower, they are addressed by an omnipresent, directionless voice.
DM: We had this discussion before, because in the ability, it has Slimy Doom, which whenever it takes damage, it becomes stunned, which is the most broken--
Player: I almost did that.
DM: I know, but I think the DND ruling, technically, they have to fail three saves before it affects them.
Player: But it's a 5th-level fucking spell. That's a lot!
DM: I know.
Player: That's lame. Three rounds for a 5th-level spell?
DM: Look. I'll say this. I'll let Mind Fire work on her for now.
Player: Oh, he doesn't look happy. I feel like I just pissed off the DM.
DM: No, you didn't piss off the DM. This spell has a lot of contention in the community, but the official DND ruling was it doesn't affect until they fail all three rolls, but as it's written, it doesn't say that. It says they're afflicted on being hit, so I'm letting it go through because you didn't choose the cheesy-ass stun-lock broken spell.
Player: It does say that after succeeding on three of these, the creature recovers from the disease, so they were already affected.
DM: Which is what I'm saying. This is between what's written in the spell and the arguments that people have made with DND on Twitter, and they clarified that's not how it works. It's a mis-type. It wasn't clear. I'm letting it work. Be happy with the book.
