Corrosive Aura (Su)

A creature that enters an ibshaunet’s aura must succeed at a DC 19 Fortitude save or take 3d6 points of acid damage. Once a creature is affected by this aura, it is not affected again unless it leaves and reenters the aura. The save DC is Charisma-based.

Warpwave Breath (Su)

An ibshaunet can exhale a 50-foot cone of entropic energy every 1d4 rounds, dealing 10d6 points of acid damage to creatures in the area of effect (Reflex DC 22 half). A creature damaged by the breath must succeed at a DC 22 Fortitude save or be subject to a warpwave. The save DC is Constitution-based.


Environment any (Maelstrom)

Ibshaunet proteans are rarely seen engines of destruction.
