All Key of the Diadem Locations in Fire Emblem: Fortune’s Weave

These specialized keys are mandatory if you want to acquire the divine license items needed to promote your units into elite divine classes. While you cannot claim these licenses or execute the promotions until you reach the Fourth Section (“The Hopes of Monarchs and of People”) of Part 3, you are free to track down and secure the keys during earlier phases of the final act. For deeper insights into promotion paths, feel free to consult our comprehensive Fire Emblem: Fortune’s Weave class guide.

Only five keys exist in total, and each one rests inside a chest located within a designated dungeon. Fortunately, none of these specific dungeons present overly cryptic puzzles or excessive hidden paths. Because the game conveniently tracks the total number of chests per area, you can easily verify whether you missed any loot before moving on.

Here are the exact dungeons where you can unearth every key of the Diadem:

• Heretic’s Cave (Thaleia)
• Cougar Woodlands (Braxithea)
• Giant’s-Print Fort (Ogmios)
• Sand-Shadow Fort (Nysiades)
• Enno Isle (Danann Sea)

How to Use the Keys of the Diadem in Fire Emblem: Fortune’s Weave

You can exclusively spend your keys of the Diadem at the Temple of the Diadem, a sanctuary that becomes accessible upon reaching the Fourth Section (“The Hopes of Monarchs and of People”) of Part 3 within the Idyia region.

Opening any one of the five sealed doors inside the temple requires a single key of the Diadem. Because the keys are completely interchangeable, you can freely choose whichever door you wish to open first, provided you have at least one key in your inventory.

Beyond each threshold, you will discover one or two chests packed with essential divine license items. If you ever want to preview what a class offers, simply interact with its corresponding statue stationed in the main chamber of the temple.

To help you prioritize which path to pursue first, here is the complete breakdown mapping each door to the specific classes it unlocks:

• Maiden’s Chambers: the Apsara
• Prophet’s Chambers: the Eternal and the Avatar
• Disciple’s Chambers: the Godhand and the Trident
• Chamber of Distortion: the Blade and Calamity
• Chamber of Sirius: the Cavalier
