Combat

A purple ooze strikes like a monstrous wave, slamming opponents with its body.

Acid (Ex): A purple ooze secretes a digestive acid that quickly dissolves organic material and stone, but not metal. Any melee hit or constrict attack deals acid damage. Stone, leather and clothing dissolves and becomes useless immediately unless it succeeds on a DC 18 Reflex save. A stone or wooden weapon that strikes a purple ooze also dissolves immediately unless it succeeds on a DC 18 Reflex save. The save DCs are Constitution-based.

The ooze's acidic touch deals 25 points of damage per round to wooden, cloth and leather objects, but the ooze must remain in contact with the object for 1 full round to deal this damage.

Constrict (Ex): A purple ooze deals automatic slam and acid damage with a successful grapple check. The opponent's clothing, wood and leather armor take a –4 penalty on Reflex saves against the acid.

Improved Grab (Ex): To use this ability, a purple 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 purple 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 purple ooze and walk into it are automatically hit with a melee attack for slam and acid damage. It resembles a gray ooze, but with a lightly translucent purple surface.

Attack from Below (Ex): A purple ooze can attack from below by slithering into the floor below the target, and dissolving the stone or wood that the target stands upon, sending them splashing into the purple ooze.

Pool (Ex): Multiple oozes can join up, forming a larger specimen. This is especially deadly when used with the attack from below ability, creating large flows and moats that surround their prey.
