Delirious Chorus (Ex)

Because of the innumerable voices and dissonant harmonies of its gibbering, saving against a delirious chorus’ gibbering grants immunity to its gibbering for only 1 round rather than 24 hours as for typical mouthers. In addition, as a swift action, a delirious chorus can magnify the gibbering of another mouther, increasing the save DC of the effect by 1 for 1 round. It cannot affect its own gibbering save DC.

Spittle Gout (Ex)

As a standard action, a delirious chorus can emit a 30-foot line or 15-foot cone of acidic spittle. All creatures in the area take 6d6 acid damage (DC 23 Reflex half).

Creatures failing their Reflex save are also blinded for 1d4 rounds (DC 23 Fort negates). After using this ability, the delirious chorus must wait 1d4 rounds before using it again. This gout is harmless to other gibbering mouthers. The save DC is Constitution-based.


Environment any underground
Organization solitary, pair, or chorus (3-6)
Treasure standard

This horrid mass of eyes, mouths, and formless flesh stares in all directions, its countless maws yammering ceaselessly.
