Incurable

Throughout your adventurer career you have learned to make the most of circumstance and achieve your goals even at great cost. You learn the feat, "Coup De Grace"

Additionally, having confronted your mortality first hand, those who look into your eyes can feel your quiet determination simmering beneath the surface. Though some may fear your illness, people respect your resolve to live. You have became accustomed with various healers and priesthoods who extend to you shelter and medical comforts. You may also receive small discounts when purchasing alcohol or illicit substances to combat your pain.

This variant seeks to add additional rules and mechanics for dealing with a painful and life-threatening affliction over a long period of time. Consider using this if you want to add a sense of urgency to the goals you have set for your character. Furthermore when playing using this variant, consider the added difficulty of the mechanics and that your character may die before finishing their story in a satisfying manner. Discuss with your DM on the rarity of and what might be required to find a cure or if you want one to exist at all.

The Affliction you suffer from is severe and untreatable by regular means. While not contagious, it eats away at the body slowly and painfully until eventually you bodily functions fail and you perish. Standard resurrection is possible but does not function as a cure, and without one you maintain any penalties  that are a result of your Affliction through resurrection.

While suffering from your Affliction you have a affliction counter. At the end of short or long rest "At Your Limit" triggers and increments the affliction counter by one up to a max of three. After filling the counter you must succeed a DC 15 Constitution Saving Throw or suffer a permanent -10 penalty to your Max Hit Points. A creature within 5ft of you, proficient in the Medicine skill can choose to help you prevent a failure by succeeding a DC 13 Medicine Check. The affliction counter then resets back to zero.

If your max Hit Points hit zero while suffering from the affliction you die. This effect can not be removed by Greater Restoration and similar effects.
