Mummy rot is a supernatural disease that dries the body from within before causing slow decomposition. It begins with extreme thirst, then progresses into weakness, failing vision, blindness, physical collapse, and eventually death.

A humanoid exposed to mummy rot through magic or by inhaling grave dust must make a Contesting Fortitude Roll. For grave dust, the DC is 14. For magical infection, the DC depends on the curse’s power.

Once infected, the victim immediately suffers intense thirst and must drink twice as much water as normal or gain 1 level of exhaustion. Every 24 hours, the victim makes a DC 17 Contesting Fortitude Roll. Each failure adds the next symptom in order. Two consecutive successful rolls halt the disease, but do not remove existing symptoms.

Remove Curse destroys the disease and heals all damage caused by it. Lesser Restoration removes the most recent symptom still affecting the victim.
