A new feature, Combo Mastery, is in the works!
Combo Mastery will allow players to upgrade an entire combo, rather than individual cards. Upgrading a combo will make it stronger for ANY recipe that creates that combo! Mastery Tokens will be available as Special Event Rewards and in the Shop.
Combo Mastery will be available for players Level 12 and up, and we hope to have this new feature go live within the next couple of weeks. This is intended to be end game content and is not for the faint of heart -- mastery will take time and dedication!
