Mitama Dance of Miracles

Dance of Miracles is the easiest way to grind Glory and, in my opinion, the least pay-to-win Mitama DLC (although, all Mitama DLC's trivialize the game one way or another). While it does remove the incentive of saving up Glory for Miracles, you still need to clear Abscesses to unlock them. Grinding 100000 Glory for example, won't give you an immediate boost in Power.
