Final Bargain

You whisper a bargain to the higher powers, your life for another.

Your soul is bounded to the afterlife.

Your HP is reduced to 0 and any method of reviving/healing is forfeited

The first time the target would drop to 0 hit points by any means, the target instead restores all health, and the spell ends.

If the target was found dead, this ability can be treated as Revivify, with no one minute restriction.

The effected target receives advantage for all future attack rolls until the end of combat when the spell ends.

If the spell is still in effect when the target is subjected to an effect that would kill it instantaneously without dealing damage, that effect is instead negated against the target, and the spell ends.
