You open a conduit to a plane of death, infusing one creature you can see within range with a jolt of negative energy. A living target must make a Constitution saving throw, taking 5d8 necrotic damage on a failure or half as much on a success. An undead target gains 5d8 temporary hit points. While it has these temporary hit points, it has advantage on its attacks.
