Aurora Essence
Use Aurora Essence to permanently increase a 10★ unit's maximum level.
By default, the maximum level for a 10★ unit is 200. Aurora Essences can be used to increase the unit's 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 |
|---|---|---|
| ★★★★★★★★★★ | 1 | 20 |
Note that 10★ units can additionally have their max level raised by another 20 levels through use of 
Prismatic Orbs, for a total potential level of 240.
For 9★ rarity units, please refer to 
Ichor.
For 8★ rarity units, please refer to 
Soma.
For 7★ and under rarity units, please refer to 
Ambrosia.
