Player: Vicious Mockery on the manticore.
DM: All righty, 12.
Player: I don't actually know what it's rolling against. What is it against?
DM: It's eight plus two, which is your proficiency bonus, which is ten. Plus your wisdom modifier. What is your wisdom modifier?
Player: My wisdom modifier, I believe it's three.
DM: It would be 13, so it hits, yeah.
Player: All right! That's one point of psychic damage and it has disadvantage on the next attack. (rasping) You should leave and protect the child. Trying to--
DM: All right, the female face grins even wider, the eyes narrow (growls).
Player: I'm going to back up.
DM: It seems like it shakes its head a bit. It seems strangely wounded briefly, but then grins at the prospect of a new meal.
Player: I'm backing up a little bit. I'm going to step back ten feet.
DM: You move back ten feet to there.
Player: Yeah, backing up.
DM: That brings us to Fjord's turn.
