SPECIAL TRAITS

• Amorphous. The crystal ooze can move through a space as narrow as one inch wide without squeezing.
• Corrode Metal. Any nonmagical weapon made of wood or other organic material that hits the ooze corrodes. After dealing damage, the weapon takes a permanent and cumulative –1 penalty to damage rolls. If its penalty drops to –5, the weapon is destroyed. Nonmagical ammunition made of wood or other organic material that hits the ooze is destroyed after dealing damage. The ooze can eat through two-inch-thick, nonmagical wood, leather, or other organic material in one round.
• False Appearance. While the ooze remains motionless, it is indistinguishable from an oily pool or wet rock.
• Partially Amphibious. Crystal oozes can survive out of the water for five hours.

ACTIONS

• Multiattack. The crystal ooze makes two Pseudopod attacks.
• Pseudopod. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 4 (1d6 + 1) bludgeoning damage plus 7 (2d6) acid damage, and if the target is wearing nonmagical leather armor, its armor is partly corroded and takes a permanent and cumulative –1 penalty to the Armor Class it offers. The armor is destroyed if the penalty reduces its Armor Class to 10. In addition, a creature hit by this attack must succeed on a DC 14 Constitution saving throw or become paralyzed. A paralyzed creature can repeat the saving throw at the end of each of its turns, ending the effect on itself with a success.

ABOUT

The crystal ooze is an aquatic variety of the gray ooze. It is semitransparent and clear, almost impossible to see in the water, and looks like nothing more than a puddle of water. The crystal ooze can grow to a length of up to eight feet and a thickness of about six inches.
