Flesh rot

Flesh rot, also known colloquially as "mummy rot" or "the mummy disease", was a magical disease that caused one's flesh to decay. It was a contagious form of the true mummy rot that was inflicted by the touch of mummies.

Acquisition
The disease was spread by touching an infected individual. It was also one of several diseases that could be inflicted by the spell contagion.

Effects
Those suffering from flesh rot experienced their flesh decaying. Sufferers were much more susceptible to injury than healthy individuals, but perhaps the biggest danger was the steady wasting away of the body, which was compounded by a 90% reduction in natural healing abilities and a supernatural resistance to cure wounds spells. Unless cured, the disease would always kill an infected individual within six months.

The visible rotting led to sufferers being shunned in any social interaction. The injuries inflicted by the disease were enough to leave permanent scars after one to two tendays of infection, with the damage steadily compounding over time.

History
The avatar of the god Myrkul was known to freely inflict flesh rot on his foes prior to and during the Time of Troubles. His version of the disease also entailed hallucinations that rendered an infected individual unable to see the flesh of others, and to perceive them instead as walking and talking skeletons.
