Travel to Venice and enter your first Scenario to unlock the augment wheel.

Augment Resonators drop from enemies in Scenarios and can be consumed to learn, or "harmonize", augments.

"Aureus of Initiation" tokens are earned by completing Scenarios successfully and can be used to purchase toolkits from Ca' d'Oro vendors in Venice to upgrade or attune the Augments you acquire in Scenarios. See "How do I upgrade my augments" for more information!
