Lungrot

Lungrot was a respiratory disease found only in the Underdark.

Acquisition
The disease affected air-breathing creatures, and was acquired by breathing the air inside ancient Underdark ruins. Most often, it infected creatures who had become trapped or sealed inside such places. Symptoms would set in within one to four hours.

Effects
Lungrot caused a steady decline in a sufferer's stamina and, to a slightly lesser extent, their physical strength.

Treatment
Only magical healing, such as remove disease, could allow an infected individual to recover from lungrot. That said, a healthy immune system&mdash;and a great deal of luck&mdash;could stave off the progression of the disease.
