False Appearance. While the void fungus remains motionless, it is indistinguishable from an ordinary fungus.  This fungus is white in color with a reddish tint towards its extremities.  It can grown in tiny cracks and remain concealed until an unfortunate victim has been exposed.

Negative Corrosion. While viod fungus may be almost harmless to living creatures, it can be most devistating to undead.  This fungus thrives on the negative energies that undead produce.  Exposure to void fungus will cause undead 1 hit point of damage per hour and this damage will be deducted permanently from their maximum hit points.

Once exposed to void fungus, the undead must cut away the exposed part of their bodies or burn it off.  If not the fungus will spread to their whole body within 3 to 4 days and the undead will ultimatly be doomed.
