Within the meta-game of Arknights Endfield, your weapons are almost as important as the people wielding them and to “tune” them past level 20, you will need the rare mineral known as Kalkonyx.
Kalkonyx is a mined crafting ingredient which can be found across Valley IV, but only in limited supply in specific locations.
While you later unlock a process to grow them back aboard your ship, you will need to manually gather a healthy supply of Kalkonyx in the meantime. You need 3 Kalkonyx every time you Tune a level 20 weapon and given the amount of Operators you need to outfit with weapons, similarly to Pink Bolete, this can add up quickly.
To keep your weapons in tip-top shape, here’s everywhere we’ve found where you can get Kalkonyx in Arknights Endfield.
The Hub Kalkonyx locations
There are 3 places in The Hub where you can get Kalkonyx. The first is in the southeast of the map, in the bottom corner of the Woodland Fringes area:

Next, you can get 6 more pieces nearby in the bottom of the Hub West area next to the Originium Byproduct Processing Center:

Finally, probably the easiest place to get Kalkonyx is in the Rockhill Passage area to the northeast:

Originium Science Park Kalkonyx location
There’s only one place to get Kalkonyx in the Originium Science Park too, but it’s easier to find than in the Valley Pass. On the edge of the main research center, you can find a mining node to the north:

The best Arknights Endfield blueprints for the early- and mid-game
For all your seed, battery, and stock bill needs

Finding the right set of blueprints in Arknights Endfield is the difference between spending hours manually configuring your base and just plunking down setups you know will work without tinkering. Which blueprints are best depends on where you’re at in the game. You can’t, for example, get a head start on advanced production with a battery blueprint if you haven’t actually unlocked the processes by which you make batteries. So your best bet is to upgrade your factory as you progress through the game, adding more efficient layouts or swapping one production set for another.
Below, we list some of the best blueprints in Arknights Endfield for the early- and mid-game, including battery farm blueprints.

The actual best blueprints for the early game, and for any time when you just want to see how a layout might work or start with the basics, are the blueprints you get by completing tutorial simulations. Once you unlock a new facility or process, you’ll see a prompt encouraging you to try it out in a simulation. These are often lengthy and tedious, but you’ll typically get a blueprint that lets you plunk down a basic setup that mimics what you just used. It takes the fuss out of planning and lets you focus just on producing materials you need.
However, as you start progressing, you’ll want to lessen the amount of space each process takes and have several other factors to consider while building. That’s when community blueprints come in handy.

You can opt for full-factory blueprints, but using process-specific blueprints is a lot easier and takes the troubleshooting out of trying to figure out what went wrong, if something were to go wrong. You also have more control over your layout this way.
Anyway, we’ve tested these blueprints from other Endfield players and found they work perfectly.

While we cautioned against using full-factory blueprints earlier, this one from seas-are-cute is an excellent option for giving you every material you need without having to bother setting up individual processing stations yourself.

Don’t hesitate to experiment with other blueprints to find what works best for you. Just make sure you have enough power output to keep everything going. Fixing a juice-less factory is much more of a pain than it sounds, so keep up with that as you build.
