Necrotic Curse

Through the unholy sciences & magics of a Dark Sorcerer, your body has been perverted by Necromancy. No longer a pure being of life, your body has been tainted by death, and undeath . . .

Your body has been perverted and is permeated with Dark Magics. As a result:

• Subrace: You gain the (Undead) subtype.
• Undead Nature: As an undead, you no longer needs to eat, drink, sleep, or breathe. You must still rest in order to gain the advantages of a short or long rest, and cannot engage in any strenuous activities when resting. You are affected normally by poisons and gas, and are vulnerable to Radiant Damage.
• Constitution Bonus: +1 to Constitution.
• Dark Intentions: You gain Advantage on Intimidation Checks, and Disadvantage on Persuasion Checks.
• Turn Immunity: You have immunity against an effect that would turn undead, and resistance to Necrotic Damage.
• Unfinished Business:  If you die or are destroyed, you may return to life. The dawn after you are killed, you will miraculously return to life. Every time you return to life  this way, one of your Core Stats is reduced by 1 (The DM Rolls for this.) As a result of your Undead Nature, you cannot be restored to life via Revivify, Raise Dead or Reincarnation Spells. As you return to life this way, your body may begin to show additional physical signs of Undeath. It may be possible to return you from Undeath via the use of a True Resurrection or Wish Spell, effectively ending your Undead Curse.
• Undead Resilience: When you would be reduced to 0 hit points, you can drop to 1 hit point instead. You can’t use this feature again until you finish a long rest
