Fire Emblem: Fortune’s Weave is a game which offers players a near infinite amount of ways to make their units stronger. From group training sessions that will raise the levels of your left-behind units to training manuals that will give you new skills to use in combat, any unit you love can be raised to a god-killing machine. One of the final methods of growing stronger in this game is Divine Classes, the strongest classes in the game which provide even stronger stat boosts than the Advanced Classes. Sadly, unlocking these power houses will take a bit more effort than usual and send you on a scavenger hunt during the most time sensitive part of the game. If you don’t want to deal with that stress, here is a quick guide on where to find all of the Keys of the Diadem in Fire Emblem: Fortune’s Weave.
All Key of the Diadem Locations in Fire Emblem: Fortune’s Weave

At the beginning of Part 3’s fourth chapter, The Hopes of Monarchs and of People, Fortuna will grant you access to the Temple of the Diadem (which is located to the east of Dagison) and instruct you on how to unlock Divine Classes. The temple has five different chambers, with each granting the player access to a new Divine Class that they can assign to their characters.
- 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
Unfortunately, each door in the Temple of the Diadem is locked and you’ll need a key to get inside, and said keys have been scattered throughout dungeons all over the continent. Each key you find can be used to open any of the chambers and earn the Divine Classes inside, but if you want to earn each Divine Class you’ll have to find every Diadem Key. Below are the locations of each Key of the Diadem.
Key 1 – Heretic’s Cave


The first dungeon with a Diadem Key isn’t too far from Dagison, just to the northwest of the capital you’ll find a dungeon called the Heretic’s Cave. Inside of this cave you’ll find a chest with the key you’re looking for.
Key 2 – Cougar Woodlands


Next, send one of your squads over to the western side of the map. Here there will be a dungeon just south of Credna’s Temple called the Cougar Woodlands. You’ll find the chest with the Diadem Key just to the left of the entrance.
Key 3 – Sand-Shadow Fort


The next key we’ll be grabbing is located in a chest inside of the Sand-Shadow Fort. To reach this dungeon you’ll first need to trek through the desert first by moving to the world map space left of the Baina Oasis and then following the southern path that appears one turn at a time until you eventually see the dungeon space.
Key 4 – Giant’s Print Fort


Your fifth key can be found in the southeast corner of the continent. Just to the southeast of Theodora’s home Megaira you’ll find a dungeon called the Giant’s Print Fort. The treasure chest containing the Diadem Key can be found atop some stairs in the eastern part of the dungeon.
Key 5 – Enno Isle


The final key, and the one you’re mostly likely to be missing due to how out of the way you’ll have to go to get it is on Enno Isle. You can reach this dungeon by setting sail from the world map spaces near Callianeira Port and from there head to the east until you reach the island.
