Promoting a character will increase its star level and can increase its level cap, meaning it can be leveled up higher. You can promote your characters via the ‘Promote Characters’ Machine, which can be found in Mike’s Basement.

Each promotion will require one additional copy of the exact matching character of same rarity, or one lower rarity.

If unsure of the promotion requirements for a certain character, you can select it in the Character Promotion screen and the game will indicate the necessary copy needed.

Please note that the copies (components) used for Character Promotion will be consumed and will therefore no longer be available on your account!

To promote a character, first select the (base) character, so the character you wish to promote, and then afterwards select the copy (component) you wish to use for this promotion. Once you have done so, simply click on the green “Promote” button, to complete the promotion.The order in which you click on the characters during Promotion is crucial to determine which character will be promoted (used as base) and which ones will be consumed (used as components).

To avoid accidentally using characters as components, always pay attention to the order in which you select the characters. The character displayed at the left will be promoted, the character to the right will be consumed.

If you are unsure of how to promote a specific character, tap on the info-button in the Character Promotion view and the game will show you a breakdown of how to promote per character rarity level.

You are also able to use the mass promotion feature to promote multiple characters at the same time. For more information on this, please read "How does Character mass promotion work?" FAQ.
