Pain Worm

Pain Worms are parasites planted by Putrid Defilers that burst from an infected monster's skull after the host dies. The vile spawn of the Putrid Defiler, Pain Worm gestate within the brain of a host monster, feeding off the demonic thoughts of the Beast. If the monster is killed while the worms remain gestating, the parasites eat their way through the Beast's brain and ultimately burrow out of its Skull in search of a new body to inhabit. It has been rumored that certain demon groups will simply imprison one of their brethren rather than risk killing the host and infecting another. Pain Worm are created by Putrid Defiler.
