Alkilith

Society
The alkilith is among the demons that disgust and terrify. These shapeless horrors are used by demon lords for assignments in areas that most demons would hesitate to travel to, for alkiliths can survive and even thrive in the most chaotic and hellish and unlivable areas of the Abyss. They are corruption and pollution made hatefully alive, making it easy to understand why they're feared by much of demonkind. Tales claim the alkilith has no limit to its size—travelers of the planes have spoken of alkiliths the size of lakes in the deepest reaches of the Abyss.

Appearance
Alkiliths are shivering messes of phosphorescent green corruption surrounded by cracked, leathery coatings, always oozing, secreting, thickening, and breaking open, with dark eye-globes covering their bodies. They are usually the size of a regular human, but they have been known to be able to shape their bodies to fit in cracks that are as small as one inch wide.

Combat
Even though alkiliths have a gelatinous shape they can move at a decent speed. The alkilith can make fast attacks in combat and in the time where someone might strike once, they can attack four times with their dreaded pseudopods of acidic slime. It's with great pleasure that the hideous alkilith destroys and pollutes nearby environments—they have even been known to ignore enemies just to defile a fresh deposit of water.
