Skills

Actions

• Pseudopod. _Melee Weapon Attack:_ +3 to hit, reach 10 ft., one target. _Hit:_ 3 (1d4+1) bludgeoning damage plus 7 (2d6) acid damage, and if the target is wearing nonmagical metal armor, the armor is partly corroded and takes a permanent and cumulative -1 penalty to the AC it offers. Armor reduced to an AC of 10 is destroyed.

Reactions

• Solidify. When the ooze is hit by an attack, it can partially solidify its body, reducing the damage it takes by 2 (1d4). If it has taken fire damage since the start of its last turn, the damage it takes is reduced by 3 (1d6) instead. The ooze can't use this reaction if it has taken cold damage since the start of its last turn.

Special abilities

• Amorphous. The ooze can move through a space as narrow as 1 inch wide without squeezing.
• Corrode Metal. Any nonmagical weapon made of metal 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 metal that hits the ooze is destroyed after dealing damage. The ooze can eat through 2-inch-thick, nonmagical metal in 1 round.
• False Appearance. While the ooze remains motionless, it is indistinguishable from ordinary fresh or curing mortar.
• Ooze Nature. The ooze doesn't require sleep.
• Ooze Resilience. The ooze is resistant to the grappled and restrained conditions, and it is immune to exhaustion and to the blinded, charmed, deafened, frightened, and prone conditions.
• Spider Climb. The ooze can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
