Mut-X
Mut-x is a biomantic mutagen created by Dr. Francis Norman Stein that is capable of rapidly adapting flesh to hostile environments. Side-effects of the Mut-x included the polyhedroozes absorbing the latent psychic energy of an area.
During the events of Session 001 - Polyhedrooze, Crumbisur Sayax bathed in a pool of water that was tainted with Mut-x resulting in him obtaining a golden glow and a resistance to radiant damage for a short period. Meanwhile, Siggy waded through some water tainted with Mut-x, and her right foot turned into a left foot, resulting in her having an abnormal gait for a short period.
