Closely resembling an edible form of rock moss through most of its life cycle, this corrupted fungus grows amply in the most barren regions. Named for the demon lord of murder, the spores can cause psychosis in the minds of intelligent creatures.
A successful DC 20 Knowledge (nature) or a DC 25 Perception check is required for a character to notice the danger this presents before coming within its spore range. When any intelligent living creature comes within 5 feet of a patch, it must attempt a DC 20 Will save to resist becoming infested with the invisible, scentless spores. Once a creature is infested, it develops a psychosis remarkably quickly as the spores rework the victim’s personality, transforming it into a murderous killer with a keen ability to hide its sadistic secret.
