• Pseudopod: Melee Weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 22 (4d8 + 4) bludgeoning damage plus 9 (2d8) acid damage. If the target is wearing nonmagical metal armor, its armor is partly corroded and takes a permanent and cumulative -1 penalty to the AC it offers. The armor is destroyed if the penalty reduces its AC to 10.
