Deep Purifier's Black Hole

Invoking the Deep Purifier, you create a 8-inch diameter floating black sphere above your head. The sphere lasts for the duration, and moves with you so it is always 1 foot above you. Ranged attacks automatically miss you, as the black hole sucks them up. This also applies to the Magic Missile spell, and anything that creates projectiles directed at you. At any point during your turn as a Bonus Action, you can throw the black hole at something. That target takes 15d8 Force damage.
