Traits

Amorphous. The ooze can pass through an opening as narrow as 1 inch wide without squeezing.

Corrosive Body. A creature or a metal object that touches the ooze takes 5 (2d4) acid damage. A nonmagical weapon made of metal that hits the black pudding corrodes after dealing damage, taking a permanent -1 penalty to damage rolls per hit. If this penalty reaches -5, the weapon is destroyed. Metal nonmagical ammunition is destroyed after dealing damage.

False Appearance. While motionless, the ooze is indistinguishable from wet stone.

Sunlight Sensitivity. While in sunlight, the ooze has disadvantage on attack rolls.

Ooze Nature. An ooze doesnt require air or sleep.

Actions

Pseudopod. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 3 (1d4 + 1) bludgeoning damage plus 5 (2d4) acid damage. Nonmagical metal armor worn by the target corrodes taking a permanent -1 penalty to its AC protection per hit. If the penalty reduces the armors AC protection to 10 the armor is destroyed.
