Armor of Sacrifice

While attuned, this armor grants +2 to AC. Once per long rest, if you are knocked unconscious, you can choose to ignore death saves, and the armor revives you with half your HP rounded down.

Cursed Item: Whenever you choose to ignore death saves, your max HP is permanently reduced by 2d6 + your Constitution modifier. You can undo this only by a Remove Curse or Greater Restoration spell.

Made from tough but flexible leather, studded leather is reinforced with close-set rivets or spikes.

Notes: Bonus: Armor Class
