There are 5 Alliance Ratings, ranked from lowest to highest:
C, B, A, S, SS

The alliance is rated based on its total power, and this rating plays an important role during events like the Battle of Destiny and the Battle of Disorder.

The higher the alliance rating, the tougher the competition, but the better the rewards.

Alliance ratings are re-evaluated for all participating alliances before each event.

To view your alliance rating, tap the (Alliance) icon at the bottom of the game screen. Your rank will be displayed on the left side.
