Soma
From Unofficial Fantasica Wiki
Use Soma to permanently increase an 8★ unit's maximum level.
By default, the maximum level for an 8★ unit is 160. Soma can be used to increase the unit's maximum level up to 180. Each Soma increases the unit's level cap by one level, and a maximum of 20 Soma can be used per unit.
Soma can can be obtained from the Bazaar, where they can be purchased for 10 Orb Points (OP) each.
