One round after reaching 0HP, you can choose to stablize at 1HP. For three rounds, your AC is 25. The round you come back you are allowed half your movement and an action. Any melee attack you make during those three rounds also does 5d6 cold damage, any spell attack does an extra 5d6 necrodic damage.
1 charge, resets after a long rest.
