How I found the best way to use the Arknights Endfield Electric Mining Rig

One of the first steps I take in the factory building gacha RPG Arknights Endfield is to set up a production line to fashion the supplies and gear I need. To get it up and running, I need to farm both Originium Ore and Amethyst, vital materials for Talos II’s development. This is easier said than done, however, as you’ll need to wrap your head around how Arknights Endfield Electric Mining rigs work. 

While I can mine the ore manually from crystals around the area, the Portable Originium Rigs that the feathered owl engineer Andre handed me are way more efficient. 

They mine Originium Ore from the crystals around the area automatically and are way more productive in getting the job done. As it turns out, they’re a little too productive.

They fill up all too fast with Originium Ore, but they won’t restart mining until I go back and collect it all. Luckily for those like me who can’t keep up with them, Electric Mining Rigs make life a whole lot easier. Here’s how I make the most of them.

To get the Electric Mining Rigs, I follow the first main story chapter, “The Broken Lands”, until I reach the end. It’s then that the last story quest, “Paving the Way,” begins with Andre explaining how we need to increase our mineral mining efficiency.

He then directs me to a cheese-string, otherwise known as a protocol data logger, a landmark that gives me a basic AIC index when I interact with it. This basic AIC index is exactly what I need to research Mining II and unlock the Electric Mining Rigs. 

The more of these inflatable tube men you find, the more new industrial structures you’ll be able to unlock. It makes a certain kind of sense, trust me. 

The biggest benefit of Electric Mining Rigs is that they automatically transport minerals to your depot. With how many times I forgot about my Portable Originium Rigs to focus on the main story, I was relieved to have mining rigs that I wouldn’t have to manually collect ore from.

These Electric Mining Rigs are also straightforward to craft. The only things I need are the Portable Originium Rigs and Origocrusts, two items I’ve made plenty of earlier in the story. 

The Electric Pylons needed to power them are crafted with five Originium Ore, a trivial amount at this stage of gameplay.

To get these Electric Mining Rigs working, they need to be placed next to an electric pylon that will power them on. These need a transmission from a nearby relay tower to get the energy they need to work, but I thankfully only need to set up one between my automation core and a nearby area filled with amethyst crystals.

This isn’t too obvious at first, but a handy stimulation mode makes it easy to learn the basics. Once I feel confident setting them up, the world of Talos II is my oyster.

After setting my first Electric Mining Rig up, I’ve already set to work crafting plenty more and placing them at all the mineral deposits I can find. Thankfully, there are plenty of mineral deposits scattered around the Core AIC Area.

I’ve found these Electric Mining Rigs have been the most consistent way to mine that all-important Originium Ore and Amethyst in Arknights Endfield. Switch up your Portable Originium Rigs for them, and you’ll have more precious ore than you’ll know what to do with.
