New Super Trust Masters!
Super Trust Master Rewards are rewards from units that have been awakened to 7★. They can be obtained by increasing their Super Trust Master percentage to 100%.
You can fuse units that are identical to your 7★ base unit to increase its Super Trust Master percentage.
The percentage value that can be obtained from units used as fusion materials varies according to the unit's rarity.
Percentage value gained by rarity:
・When fusing a ★5: +50%
・When fusing a ★6: +50%
・When fusing a ★7: +100%
You can obtain special rewards when you fuse an identical unit to a particular 7★ base unit for the very first time.
