Arknights : Endfield can be quite challenging for new players, with a cluttered interface and a plethora of different currencies and storage options. At first, it’s overwhelming, and the inevitable question arises: “How do I open the treasure vault?” It’s literally the most valuable place, as it’s where you’ll find your weapons, mercenary permits, and other valuables.
Let’s quickly figure out how to open the storage compartment and what you can find in it.
How to open a vault of valuables
It’s quite simple to do. Just press the N key on PC. Or, using the interface, open the hidden features tab and look for the weapon crate icon. This is your valuables stash.
New in the game:
Cupric Ore • Cupric Part • Cupric Component • Wulin CE Battery • Wulin Complete Factory • Qinbo Camp: Aurilens • Heavy Xyranite • Getonite Part • Completed Blueprint 1.3 •
What is stored in the storeroom?
Now let’s take a look at what you can find there. The first tab contains all the weapons you own and their duplicates.
The second tab contains essences, special items that significantly enhance the characteristics of weapons.
On the third one you can study the available equipment for your characters.
The fourth section contains power-up items. Experience cards, items for character ascension, and weapon upgrades. Seeds for growing rare resources on your ship are also stored here.
The fifth tab is the least interesting. It contains mission items.
And finally, the last and most delicious. Besides gifts for your operatives, here you can find recruitment permits (character upgrades), weapon crates of your choice, and all sorts of exchange coupons.
Where to find the Permit to Select a Destination
In a minor update on February 5, 2026, the developers added a new item to the game—Assignment Permission. With it, all players can invite any operator from the standard banner to their team once.
You can find this item, of course, in the Valuables stash, under the final “Valuables” tab. Click “Use” and select the desired operative.
