You create a magical zone that inverts healing energies and regeneration in a 15-foot-radius sphere centered on a point of your choice within range. Until the spell ends, any creature that that resides within the spell's area while regenerating or being healed must make a Constitution saving throw. On a failed save, a creature will take the amount healed or regenerated as necrotic damage. On a successful save the healing or regeneration is simply negated.

An affected creature will suffer from the inverted healing for up to a round after leaving the zone.
