Aurora Essence
Use Aurora Essence to permanently increase a 10★ unit's maximum level.
By default, the maximum level for a unit is 20 x the unit's rarity. Aurora Essences can be used on 10★ and 11★ units to increase their maximum level an additional 20 levels (each Aurora Essence increases the unit's level cap by one level, and a maximum of 20 Aurora Essences can be used per unit).
Each use of Aurora Essence will increase a unit's level cap by a set amount. That amount depends on the rarity of the target unit as shown in the table below:
| Rarity | Levels granted per Aurora Essence |
Max Aurora Essences per unit |
|---|---|---|
| 10★ | 1 | 20 |
| 11★ | 1 | 20 |
10★ units can additionally have their max level raised by another 20 levels through use of 
Prismatic Orbs, for a total potential level cap of 240.
11★ units can additionally have their max level raised by another 20 levels through use of 
Celestial Orbs, for a total potential level cap of 260.
