Personal Bosses are solo instances where you have to fight certain bosses alone. You’ll be able to get exclusive rewards upon completion, even if you don’t get a 3-star. These are standard bosses and the higher your CP, the higher your chance of securing a 3-star evaluation. Like other boss battles, you can do this manually or set your character in auto-combat. After securing a 3-star evaluation, the next boss will be unlocked. You can also Blitz the previously 3-starred bosses to get their rewards without fighting them. You have 2 chances to tackle Personal Bosses per day.
