Phoenix Choker

When the wearer drops to 0 hit points and does not die outright, the choker ignites in harmless phoenix flame and is consumed. The wearer becomes stable and is wrapped in a burning ash cocoon. At the end of 10 rounds, if the wearer's body has not been destroyed and the cocoon has not been dispelled by magic such as Dispel Magic against DC 15, the wearer returns to consciousness with 1 hit point and gains 2d6 temporary hit points. While cocooned, the wearer is incapacitated, cannot move, and has resistance to fire damage. The cocoon sheds bright light in a 10-ft radius.
