Undead reanimation

When hit point hit 0 instead of making a saving throw you turn undead and regain half health. you are now vulnerable to radiant attack. take an extra 2d6 of damage every time a radiant attack hits you.

to turn back to normal you must deal the same amount of necrotic damage as the max amount of health you currently have.

until you do so you will remain undead and no one but the undead will like you and be attacked by anyone in cities or towns that arent undead.
