What are some chronic illnesses that can only occur in a fantasy setting?
Partial transformation - mummy rot is slowly turning you to sand, a near miss from a medusa left you with partially stoned body parts, etc.
Hypnotic suggestions from being mind controlled persist after the controllerβs death, causing the victim to occasionally take actions to support the cause of a mind flayer cult that no longer exists.
Repeated demonic possession has left the patient with permanent gaps in their soulβs defenses, causing them to immediately get re-possessed if they go outside a consecrated area.
Post-resurrection trauma as the revived soul remembers an unpleasant afterlife.
Magical healing can get very weird if something is stuck in the wound. Itβll get you back on your feet, but you can get outcomes like βthereβs a chunk of wood fused into your chest because the magic couldnβt figure out how to get the arrow out of your chest and just healed it in place,β and this can cause mobility issues or infection vectors down the line.
