ENIGMA is the newly-made fifth-generation combat orbment developed by the Epstein Foundation. In addition to enabling new Arts, it is the first orbment with built-in communications functionality. In conjunction with the Orbal Network Project, the Crossbell government and its Bracer Guild branch accepts the Foundation's request to beta-test its communications using expensive relay terminals within the city.
Like the previous battle orbments in the series, its basic architecture allows installing Quartz to strengthen the user’s physical capabilities, enabling Orbal Arts, but marking the debut of portable communication between places.
- Portable Communication: One of the primary functions to keep contact with fellow users anytime and anywhere.
- Orbal Arts: One of the primary functions for self-enhancement and combat magic by inserting quartzes into slots. For this new module, new types of quartzes are required to fit the slots in adjustment to the series' gaming balance.
- Master Quartz System: A new feature as of the Trails to Azure chapter, where new Quartzes that are inserted into the central slot where it can level up and gain new abilities.
