The keys of the Diadem are essential items in Fire Emblem: Fortune's Weave, found during the Salvation arc and used to unlock divine classes. These unique keys are discovered within chests in specific dungeons, primarily in Part 3 of the game, as players focus on leveling units and addressing world map gates.
Key of the Diadem Locations
There are a total of five Keys of the Diadem to collect. Each key is hidden within a chest in one of five distinct dungeons. The game indicates the number of chests in each dungeon, making it possible to track down any missed ones. These keys are necessary to unlock divine license items, which in turn allow characters to change into divine classes. While the divine classes themselves become accessible in the Fourth Section of Part 3, titled "The Hopes of Monarchs and of People," the keys can be found earlier.
The dungeons containing a Key of the Diadem are:
- Heretic's Cave (Thaleia)
- Cougar Woodlands (Braxithea)
- Giant's-Print Fort (Ogmios)
- Sand-Shadow Fort (Nysiades)
- Enno Isle (Danann Sea)
Using the Keys of the Diadem
The Temple of the Diadem, located in the Idyia region, becomes accessible at the start of the Fourth Section of Part 3. Here, one Key of the Diadem is required to open one of the five doors. The keys are not specific to any particular door, offering flexibility in choosing which divine class to unlock first.
Each door leads to a chest containing divine license items. Players can interact with statues in the Temple of the Diadem's main room to view descriptions of each class. The five doors and their corresponding divine classes are:
- Maiden's Chambers: Apsara
- Prophet's Chambers: Eternal and Avatar
- Disciple's Chambers: Godhand and Trident
- Chamber of Distortion: Blade and Calamity
- Chamber of Sirius: Cavalier
