The Regenerator

Taking this feat, you gain the ability to regenerate after death. But it comes at a cost:

• You can no longer take Death Saving Throws, as they all fail automatically. 
• Upon dying, you must take 3 minutes, remaining vulnerable to a permanent defeat, to wrap up your character's relationships and decide what stats you will nerf. 
• Your character will regenerate entirely to full HP but will lose all previous personality, may change species, gender and/or looks entirely, only remembering their past selves, and you will be forced to lower their stats manually by one point for every use of this feat.
• You cannot attune weapons or armour, only other items.
• If you are attacked during your regeneration process, you will die proper.
