Demonic Blood is an ailment that occurs when a character is exposed for too long to the Rogue Wilderness - normally it takes several days for the ailment to take hold and it gradually worsens the longer an individual stays within the Rogue Wilderness, though after three or four years it eventually subsides as it reaches a critical stage.


Demonic Blood causes the afflicted character to slowly mutate in appearance into the form of a stereotypical red-skinned devil, the transformation is painful and disfiguring but rarely life-threatening - those who have supernatural abilities or superhuman enhancements are afflicted with a secondary curse in the fact their powers gradually become weaker until at the critical stage they vanish completely.
