The hum of the rig was deafening, a constant reminder of the stakes. A single miscalculation, a flawed component, and the entire operation could grind to a halt, leaving you stranded. Securing a reliable Ferrium supply in Arknights Endfield isn’t just about progress; it’s about survival.
The twist? There’s no straightforward “Ferrium Mining Rig” node in the upgrade tree. Instead, you’ll need the Electric Mining Drill Rig MK II, which turns Ferrium mining into an automated process. Here’s how to get your hands on it.
Electric Dreams: The Road to Automated Ferrium
Remember your first base building game? The sheer joy of watching those resource numbers tick up, slowly but surely turning into a mighty fortress. Now, imagine that, but amplified. In Arknights Endfield, automation is the name of the game. You begin by following the main storyline to the Mystery in the Building quest. Completing it earns you a Basic Expansion Core, acting as a key to opening up Ferrium Ore possibilities.

What upgrade is needed for Electric Mining Drill Rig MK II?
Next, use that Basic Expansion Core to acquire Basic AIC III from the upgrades tree. Completing the Mining III upgrade unlocks the Electric Mining Rig MK II template itself. This is where the magic starts. This template allows you to craft that much-needed automated system, your personal Fort Knox for Ferrium Ore.
From Blueprint to Reality: Constructing Your Electric Mining Drill Rig MK II
Ever watched a construction crew in action? The precision, the coordination, the way disparate parts become a functional whole. That’s the energy you need when deploying the Electric Mining Drill Rig MK II. With the template ready, scout a location rich in Ferrium. Place the rig directly on the deposit to kickstart the mining operation. Here’s what you’ll need to build it:

- 1x Portable Originium Rig
- 10x Ferrium Parts
How long does it take to build the Electric Mining Drill Rig MK II?
Think of this process like baking a cake. The Basic Expansion Core is your special ingredient, the Electric Mining Drill Rig MK II template is your recipe, and the Portable Originium Rig and Ferrium Parts are your supplies. Assemble it all correctly, and you’ll create something that not only tastes good but also has tremendous utility.
Reaching this stage will take time and resource management; however, the reward is worth it. Once set up, these automated Ferrium Ore mines will be a game-changer, freeing you to focus on other challenges. A smooth sea never made a skilled sailor. But with automated mining, the seas of Arknights Endfield become that much smoother, don’t they?
