Bane of the Realm

You summon a spirit of immense power, that overlaps with your form. As this happens, nobody, including allies, can see your form. Instead, they see a being of darkness, around 8 feet tall though it has a presence of a being that is immensely, borderline incomprehensibly large. It gives off an aura of incredible dread and fear. All targets within range, excluding targets you choose to remain unaffected, must succeed on a wisdom saving throw against your spell save dc. On a success, the target becomes frightened, and if they attempt to make an attack against you, this must succeed on another wisdom saving throw to do so. On a failure, they instead lose their mind briefly with fear, and attack the closest target to them. On an initial failure, the previous effects still apply, and the target also takes a number of D6 equal to your spellcasting modifier worth of necrotic damage, and the same number worth of D6 Psychic damage.
