Sweat beaded on my forehead as the weapon stubbornly refused to tune. Hours of grinding, all for this. The digital hammer icon taunted me, a constant reminder of the resources I lacked. If you’re also hitting a wall in Arknights Endfield, that wall is probably made of Kalkonyx—and you need a lot of it to keep your gear competitive.
Kalkonyx is your ticket to weapon tuning, that critical process that keeps your squad ahead of the curve. But this mineral doesn’t exactly grow on trees; it trickles in slowly. Knowing exactly where to focus your search can save you hours and guarantee you always have enough to push your favorite 6-star Operator to the next level. This is where to find it and how to farm it efficiently.
Kalkonyx Locations in Arknights Endfield
My first instinct in any game is always to explore, but time is always against you. In Arknights Endfield, you can find Kalkonyx by mining at specific, rare sites scattered across the first four Valley IV areas. Specifically, keep your eyes peeled in these locations, each hiding six Kalkonyx deposits:
- The Hub (Core AC Area) – 2 sites
- The Hub (Originium Byproduct Processing Center) – 2 sites
- Valley Pass – 1 site
- Originium Research Park – 1 site
- Aburrey Quarry – 1 site
For a detailed visual guide, check out the maps below:
Don’t forget that tuning weapons in Endfield also demands Cast Dies (5x for levels 20/40). You can grab these by completing the Protocol Space: Weapon Tune Challenge at The Hub or via the Acquisition Center. Acquisition Center awards aren’t tied to gacha mechanics or premium currency, so breathe easy.
What is the fastest method to acquire Cast Dies?
The fastest method for acquiring Cast Dies in Arknights Endfield is participating in the Protocol Space: Weapon Tune Challenge at The Hub. Consistently completing this challenge provides a steady stream of Cast Dies. While the Acquisition Center is another source, challenges offer a more reliable and repeatable way to gather the necessary materials for weapon tuning, allowing you to quickly enhance your arsenal.
Advanced Kalkonyx Farming in Arknights Endfield
I once heard a pro gamer say, “The real game begins after the tutorial.” Once you’ve cleared those initial mining locations, the Growth Chamber becomes your primary source. You can access the Growth Chamber once your Control Nexus hits level 2, so keep plugging away at the main story.
Once open, the Growth Chamber lets you cultivate Kalkonyx using special seeds. Each seed (crafted using Kalkonyx) yields three units of the resource. However, patience is a virtue; each seed takes over 17 hours to mature. Kalkonyx is like compound interest; the more you invest early, the greater your returns.
Is there a shop where I can buy Kalkonyx?
Yes, you can purchase Kalkonyx at Anton’s Garden Shop, located in the Worker Dorms within The Hub. To get there, simply head past the restocking center. Each unit costs 300 Stock Bills.
Alternatively, you can purchase 3 Kalkonyx units from Anton’s Garden Shop in the Hub’s Worker Dorms (past the restocking center) for 300 Stock Bills each. It’s not a long-term solution, but it can help in a pinch. At a price of 300 Stock Bills, it will cost you around €2.75, based on current conversion rates.
What other resources should I farm early?
Alongside Kalkonyx, prioritizing the early collection of Polymerized Gel is a smart move. This resource is frequently needed for Operator upgrades and base construction, making it a steady bottleneck as you progress. Diversifying your resource gathering efforts early allows for smoother advancement and prevents frustrating roadblocks later on.
Mastering Kalkonyx farming separates the casual players from the hardcore strategists in Arknights Endfield. Are you ready to optimize your resource gathering, or will you be left behind in the dust?
