In The First Descendant, you need to farm “Encrypted Vaults” for specific materials, but what are they and how can you find them?
Why are “Encrypted Vaults” relevant?
- If you want to improve your defensive values or the damage of your weapons and descendants, you need to equip modules.
- To equip more modules, you should have as high a module capacity as possible and reduce the capacity costs of your modules by adjusting the socket types of your modules.
- To change the sockets of your modules, you need crystallization catalysts.
- To increase your module capacity, you need Energy Activators (your descendant module capacity also increases with your Master Rank).
- If you want to craft crystallization catalysts or Energy Activators, you need “Mix Energy Remnants” and “Conductive Metal Foil,” which you can only get from Encrypted Storage Boxes or (Precise) Encrypted Vaults.
What are Encrypted Vaults?
“Encrypted Vaults” (in German: Verschlüsselte Tresore) are containers from which you can obtain specific materials. They are locked and must be opened with a so-called code analyzer.
There are blue and purple vaults as well as corresponding analyzers. The blue vaults contain fewer materials but are easier to crack. The purple vaults can be quite challenging.
When you use a code analyzer on a vault, it gets consumed. Then a mini-game starts. Beware, the analyzer is also consumed if you fail at the mini-game.
Locations of Encrypted Vaults – How and where do you find them?
Encrypted Vaults can be found in various areas in the world of The First Descendant. The regions “Vespers” and “Agna Desert” are particularly important.
If you want to find an encrypted vault, you need to use your scanner. To do this, press the Tab key on the keyboard or the right stick on the controller.
- If you look in the direction of an Encrypted Vault, you will hear a signal sound, a kind of beeping.
- If you look in a direction where there is no encrypted vault, you will not hear any sound.
How far you are from a vault does not affect the volume or type of sound – only the direction matters.
We will update the article in the future with maps where you can find all encrypted vaults and target them specifically. Until then, you can use the vault we recommend as a farm spot in the next paragraph.
Farming “Encrypted Vaults” – This vault is easy and quick to farm
Here you will find a vault that gives you Mix Energy Remnants: In the Agna Desert, there is an encrypted vault in the area “Cinnabar Wasteland” that you can reach quickly and therefore farm reliably. This vault gives you Mix Energy Remnants – the material you need for the crystallization catalyst.
You can simply spawn at the outpost (Outpost) in the east of the map in the “Cinnabar Wasteland” area and from there run west along the edge of the map. There, after a few meters, you will find a hole in the ground that leads into a cave.
In this cave, you will find ammunition barrels as well as an elevation on which the Encrypted Vault stands. It spawns there reliably. This means: once you have opened the vault, you can return to Albion and then travel again to the vault in the Agna Desert and collect it again.

If you have found the way to the encrypted vault once, you can farm Mix Energy Remnants this way as often as you want. The YouTuber easynow shows in a video exactly how you need to run for this (via YouTube).
Farming Code Analyzers – Here you will find keys to the vaults
If you need to farm code analyzers to open vaults, YouTuber Moxsy recommends a battlefield mission in the area “Barren Land” – this is only available in hard mode, so after finishing the story.
To play the mission, travel to the outpost “Rockfall” in the west of the region “Barren Land”. A few meters east of the outpost, you can then play the battlefield mission “Ambush Site”.
This mission lasts a maximum of 3 minutes, ideally only about 30-40 seconds, and brings not only code analyzers but also Kuiper Shards. This is also an important resource you need to upgrade your modules.
YouTuber Moxsy shows on his channel not only how you can farm code analyzers but is considered a reliable source for helpful videos in the community of The First Descendant.
