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.
Star Keys are obtained from Star Tokens and can allow you to open a Star Chest! Collecting a certain amount of Star Tokens can earn you a Star Key, which increases every time.
You can also buy the remaining amount of Star Tokens with Coins, with a ratio of 300 Coins/Star Token.
| Star Keys Obtained | Star Tokens needed per Star Key |
|---|---|
| 1st | 20 Star Tokens |
| 2nd | 50 Star Tokens |
| 3rd | 100 Star Tokens |
| 4th and more | 500 Star Tokens |
Star Tokens are obtained from multiple sources, such as evolving Characters, through the Squad Journey, in the Gem Pass, Shop offers, or through other events. 20 Star Tokens can give you 1 Star Key to open a Star Chest!
