You hold the scepter over a creature you touch as you cast this spell, linking their spirit to the jade so that death passes them by.

The creature is immune to necrotic energy, any spell or effect that would reduce its maximum hit points, any spell or effect that would reduce its ability scores, and any spell or magical effect that would kill it outright.

The next time that creature would die or be reduced to 0 hit points for any reason, they are restored to 50 hit points (or to their hit point maximum, if less than 50) instead and the spell ends.
