Disgusting Demise (acid, poison) When the grothlut is reduced to 0 Hit Points, its digestive organs rupture, unleashing alchemical acid and poison upon all creatures in a 30-foot emanation. Each creature in the area must succeed at a DC 19 Fortitude save or take 2d6 acid damage and become Sickened 1 (double damage and Sickened 2 on a critical failure).

Piteous Moan (auditory, aura, concentrate, emotion, mental, occult) 60 feet.

Each nongrothlut creature that enters or starts its turn within the area must succeed at a DC 17 Will saving throw or become Sickened 1 (Sickened 2 on a critical failure). The creature then becomes temporarily immune for 1 minute.

The grothlut can Dismiss this aura.

A grothlut usually does not begin moaning until it senses the presence of a non-grothlut creature, and it usually stops once it doesn't sense any more such creatures.
