A gray ooze can grow to a diameter of up to 10 feet and a thickness of about 6 inches. A typical specimen weighs about 700 pounds.
A gray ooze strikes like a snake, slamming opponents with its body.
Acid (Ex): A gray ooze secretes a digestive acid that quickly dissolves organic material and metal, but not stone. Any melee hit or constrict attack deals acid damage. Armor or clothing dissolves and becomes useless immediately unless it succeeds on a DC 16 Reflex save. A metal or wooden weapon that strikes a gray ooze also dissolves immediately unless it succeeds on a DC 16 Reflex save. The save DCs are Constitution-based.
Improved Grab (Ex): To use this ability, a gray ooze must hit with its slam attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can constrict.
Transparent (Ex): A gray ooze is hard to identify, even under ideal conditions, and it takes a DC 15 Spot check to notice one. Creatures who fail to notice a gray ooze and walk into it are automatically hit with a melee attack for slam and acid damage.
