Ooze, Crystal

A seemingly mundane puddle, patch of moist stone, or glistening rock is suddenly revealed to be more as a terrible pseudopod lashes out.

Acid (Ex)

The digestive acid that covers a crystal ooze dissolves metals and organic material, but not stone. Each slam and constrict attack deals 1d6 additional acid damage. Armor or clothing worn by a creature grappled by a crystal ooze takes the same amount of acid damage unless the wearer succeeds on a DC 20 Reflex saving throw. A wooden or metal weapon that strikes a crystal ooze takes 1d6 acid damage unless the weapon's wielder succeeds on a DC 20 Reflex save. The ooze's touch deals 12 points of acid damage per round to wooden or metal objects, but the ooze must remain in contact with the material for 1 full round in order to deal this damage. The save DCs are Constitution-based.

Transparent (Ex)

Due to its lack of vivid coloration, a crystal ooze is difficult to discern from its surroundings in most environments. A DC 15 Perception check is required to notice the ooze. Any creature that fails to notice a crystal ooze and walks into it automatically suffers damage as if struck by the ooze's slam attack and is immediately subject to a grab attempt by the ooze.

Paralysis (Ex)

The crystal ooze secretes a paralytic toxin that causes those whom it strikes to become paralyzed for 3d6 rounds if they fail a Fortitude saving throw DC 20 (the save DC is Constitution-based).
