We continued deeper into the lair. The psychic screams soon became louder, and we found it nestled in an ancient cistern: two gibbering mouthers, abominations screaming in this plane and in our minds. It was horrible.
The psychic damage crippled Curie, and the mouthers siphoned some of her magical acumen to turn against us. And as Lily cut into the mouther, more and more mouths with fanged teeth grew within its mass.
Curie's inner magics grew to a pitch, and she unleashed an amplified flame that erupted in a wave at the nearest mouther -- as well as Thorek and myself.
Everyone survived, and we took stock as everyone cleaned up. The well where the mouthers were feeding had another problem: gigantic [Large] hermit crabs at the bottom, blocking something.
