Ichor Sticker (5e Creature)
From D&D Wiki
Large monstrosity, lawful evil
Ichor Sac. A creature that hits the ichor sticker with a melee attack while within 5 feet of it takes 6 (1d12) acid damage.
Amphibious. The ichor sticker can breathe air and water.
Multiattack. The ichor sticker makes three attacks, two with its tentacle and one with its ichor stream.
Tentacle. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 8 (2d6 + 1) bludgeoning damage.
Ichor Stream. Ranged Weapon Attack: +8 to hit, range 40/60 ft., one target. Hit: 26 (4d12) acid damage. In addition, nonmagical armor worn by the target is partly dissolved 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.
Filled to the brim with powerful ichor, these squid-like abominations spew their corrosive bio-fluid at their prey. Found deep within the brain of Cthulhu's lair, these disgusting beasts resemble a lump of pale flesh with cloudy eyes and several tentacles flailing beneath it, all surmounted by a clear bulb filled with a roiling yellow fluid.
