Devil chills

Devil chills was a disease spread by certain types of devils.

Acquisition
Many types of devils could be carriers for the disease&mdash;including barbazu, erinyes, and pit fiends   &mdash;and such carriers did not experience any symptoms despite being contagious. The disease was spread via the bites and septic claws of infected devils, as well as by the filthy beards of the barbazu. The disease could also be contracted upon exposure to a devil's blood, and so some devils were known to smear their infected blood onto their favored weapons before battle.

Effects
Sufferers of devil chills experienced a steady wasting away of their physical strength.

While a healthy individual could recover naturally from devil chills, the disease was stubborn and required a longer recovery period than most other illnesses.

History
As of the mid-to-late 14 century DR, three erinyes infected with devil chills&mdash;Alecto, Tisiphone, and Magaera&mdash;were charged with guarding a portal in the Fields of Nun that lay along the Trail of Tears, a pilgrimage route for the devout of Tempus. These guardians&mdash;alongside their likewise infected barbazu minions&mdash;were tasked with imparting the lesson that war is but one way that people die, with disease being a clear and obvious alternative.

Rumors & Legends
The archdevil Bel was rumored to be infected with devil chills.
