Krilosis

Wounds do not heal​
  The purple rash that accompanies Krilosis flares up without warning, each angry welt a reminder of the impending danger to come.
  As the itching spreads across the body of an afflicted person, they know that their wounds will not heal. It is a curse that turns even minor injuries into potentially fatal ones.
  Those who suffer from Krilosis must be ever-vigilant, knowing that a flare-up could happen at any moment. Their fate hangs in the balance, depending on whether they can avoid injury until the disease runs its course.
  The unpredictable nature of Krilosis makes it a terrifying affliction. Those who suffer from it can never be sure when their body will betray them, leaving them vulnerable to even the slightest scratch or cut.
