A devilfish can attack with its savage bite whenever it makes a successful grapple check. This attack is in place of any other action made with a successful grapple check. The bite threatens a critical hit on a roll of 18–20, and injects the target with poison as well.
A devilfish’s blood is infused with fiendish magic. Once per day, as a swift action, a devilfish can emit a night-black cloud of this foul liquid, filling a 20-foot-radius cloud if underwater, or a 20-foot-radius burst on land. In water, the blood provides total concealment for everything but a devilfish (which can see through the blood with ease); on land the slippery blood coats the ground, making the area difficult terrain. The blood persists for 1 minute before fading. Anyone who enters a cloud of the blood in the water or who is within the area of a burst of blood on land must make a DC 15 Fortitude save or be nauseated for 1d4 rounds—this save need be made only once per cloud. The save DC is Constitution-based.
