Vambracer of Vampiric Hunger (Cursed Item)

The vambracer of Vampiric hunger.
This cursed item has no legends or oragins known. Its as if its dark will simply wished it's self in to existence. Once placed on ones wrist the vambracer can only be removed by very powerful magics.

Stats: +1AC, +2AC vs Radiant or holy sources.

In use:
Every time the player does damage (rolled a damage die) they are healed 1hp. But any and all healing actually harms instead, equal to the amout of HP that should have been healed, even natural healing. Even natural resting drains life and only drawing blood will heal.
