You summon a shadowy manifestation of hunger. The Shadowfiend appears in an unoccupied space within range. On each of your turns as a bonus action, you can command it to make a melee spell attack (using your spell attack modifier) against a creature within 5 ft. On hit, it deals 2d10 shadow damage and restores half that amount to you as healing.   The Shadowfiend has AC 12, HP equal to twice your priest level, and uses your spellcasting ability for all saves. If reduced to 0 HP or the duration ends, it vanishes.
