Bebilith

A bebilith was a massive demonic spider the size of a plow horse. They delighted in causing suffering and pain in others, but especially so in demons whom they hunted for food. The bebilith seemed to be some form of supernatural demon predator.

Bebiliths had spider-shaped bodies, with long fore-legs ending in razor-sharp claws. These claws were used to penetrate and rip armor plating from the bebiliths' foes. Just as with spiders, bebiliths had a lethal bite, but rather than a venom (to which demons were immune), they injected a vile fluid, a type of necrotic liquid, that caused accelerated rotting of the flesh.

Bebiliths were incredibly aggressive and would attack anything they saw.
