Collections keep track of the treasures you come across while exploring the Mirrorverse. You may access your collections by tapping the Collections button in the top-left of the home screen.
Your collections are organized into three categories: Guardians, treasures, and featured. Fulfilling the requirements in each sub-category will allow you to claim rewards. You can keep track of your progress with counters below each collectible as well as the collection requirement listed in the top-right of the window.
This category contains Guardians' collection sets, tracking them and their talents. These treasures can be obtained from opening crystals.
Collecting the Guardian as well as all of their talents will earn you rewards.
Collectibles in this category track the treasures you will find along your journey in the Mirrorverse. Treasures are obtained through exploring specific routes on quest maps.
Featured sets are available to collect for a limited time during specific event periods. These sets provide you with exclusive rewards that may even assist you in the event in question.
