Agonizing Cries (auditory, aura, emotion, mental) 30 feet. The screaming sulfur constantly shrieks with the pained wails of countless spirits. A living creature that enters or starts its turn in the aura must succeed at a DC 26 Will save or become frightened 1 as long as it remains in the aura (frightened 2 on a critical failure). A creature that succeeds is temporarily immune for 1 hour.

Rejuvenation (divine, necromancy) Blessing the site where the screaming sulfur was formed and burying whatever dead remain allows the spirits within the screaming sulfur to move on to the afterlife, rendering it inert.

Choke [>>] (divine, illusion, mental) The screaming sulfur bombards all creatures within its Agonizing Cries aura with visions of death and a feeling of suffocation. Each creature takes 4d6 mental damage (DC 26 basic Will save).
