"Dwelling deep within dark caves and sewers, the Muckspawn is a vile mass of acidic slime. It moves slowly but with relentless intent, burning through armor, flesh, and sanity alike. Its very presence radiates a stinging aura of caustic fumes. Contact with the Muckspawn leaves most creatures reeling, drained, and impaired by the pain of its corrosive touch..."

Heads UP!!!

Unlike many creatures, slimes such as the muckspawn have the natural ability to travel along the walls and ceilings of dungeons.

Adventurers skulking through subterranean labyrinths are forewarned to always be watching – these corrosive slimes can preemptively attack a party from above...
