Ooze: Immune to mind-influencing effects, poison, sleep,
paralysis, stunning, and polymorphing. Not subject to critical
Blindsight (Ex): An ooze's entire body is a primitive
sensory organ that can ascertain prey by scent and vibration
within 60 feet.
Improved Grab (Ex): To use this ability, the gray ooze must
hit with its slam attack. If it gets a hold, it can constrict.
Acid (Ex): A gray ooze secretes a digestive acid that quickly
dissolves organic material and metal. Any melee hit deals acid
damage. The ooze's acidic touch deals 40 points of damage
per round to wood or metal objects. Armor or clothing dissolves
and becomes useless immediately unless it succeeds at a Reflex
save (DC 19). The acid cannot harm stone. A metal or wooden
weapon that strikes a gray ooze also dissolves immediately unless
it succeeds at a Reflex save (DC 19).
Constrict (Ex): A gray ooze deals automatic slam and acid
damage with a successful grapple check. The opponent's
clothing and armor suffer a -4 penalty to Reflex saves against
Camouflage (Ex): It takes a successful Spot check (DC 15) to
recognize a motionless gray ooze for what it really is.
