Bone rot was a disease that could cause bones to become brittle and rot away. It was prevalent in swamp areas containing the dead, particularly graveyards and battlefields.[1]

The disease was contracted through contact and had an incubation time of between one and three days. The devouring of the victim's bones caused a loss of dexterity, and made bones more likely to shatter, such as if struck by a blunt weapon.[1]
