Summary[]
Star Chests are the most valuable Chests of Squad Busters, being the best source of progression in the game! Obtain Star Tokens by Evolving Characters, through the Squad Journey, in the Gem Pass, or through other events. Star Chests can give you new Characters, Super, Ultra or Ultimate Evolutions of Characters you already own (not Classic though!). After opening 10 Star Chests, the next one is guaranteed to get you an Ultra or Ultimate.
Top-5 Streaks and Chest Multipliers don't affect your odds at all.
