#Cuprium
stayed up until 4 AM PERFECTING my cuprium ore setup (slamming it into a corner of the Core AIC Area in Wuling and not ever wanting to think about it again) (will have to redo everything the instant we get one more node of cuprium ore)

Finished my capitalism venture (setting up cuprium production in endfield) so now I can go kill some gods (play ff16)

8 Cuprium Powder lines for 1 Hetonite line is taking the PISSSSSSSSSSSSS though

Anyways, had to completely revamp my Core AIC area but it now includes
-4 Xiranite Production lines (including the 12 farms needed to sustain them)
- 2 Xircon Lines
- 2 Cuprium Part lines and 1 Cuprium Bottle line
- 1 SC Battery Line
- All of the waste is processed on-site

I just set my Cuprium usage to 240/min. Was tired of waiting. When my Cuprium Ore runs out, it will revert back to the 6-lane efficiency anyways.

When the May 14 update comes, it will switch back to max efficiency. Hopefully they give us more than Cuprium

Back in Arknights: Endfield, my birb supervisor's bothered about Wuling's xiranite and cuprium supply. The extraction rate can't support having all high-value items on their max rate. 🥲

Current strategy is to hoard all current items before complete devotion to pyrrolite.

This means I can actually work with my outpost to make the second SC battery line and then either Yazhen Syringes or Cuprium Components if I want to take a slight efficiency hit

I did in fact run a bunch of conduits and set up a bunch more cuprium refining to feed it sewage. no, it was not worth the effort

fitting 4 more sky forges + utilizing the new cuprium nodes

After dropping Endfield for a while because doing dailies is a bigger chore than factory building, I genuinely enjoyed locking in today and remodeling my factory w/no blueprints to meet the production quota on the AIC event. If my math is right, I did so just in time to get the trimmed medal!

Pic 1: Dense Originium Powder Spacesaver build
Pic 2: SC Wuling Battery + Cuprium Bottles Spacesaver build(PAC distribution included)
Pic 3: Cuprium Part, Yazhen Syringe A(Efficient) and C(Slow) build
Pic 4: Sandleaf Production(for the PAC distribution)

Finally done with the event shop. I can finally disable the temporary gourd line.

And now we wait for the Wuling area expansion on Thursday. Besides Cuprium, I hope they will give us extra originium and ferrium deposits >__<

Nice. I just started mining cuprium, so I'm about to do a lot of retooling.

I'm guessing that cuprium is the new material for syringes and batteries? That should free up the low ferrium supply for something else.
March 14, 2026 at 3:27 PM
hmm.. gonna have to re-do my factory to fit 4 more sky forges and use the additional cuprium

The previous blueprints were a balance of fluid & belts - which was manageable to figure out.

This, on the other hand, mostly fluid & has me confused of the ratio for each line & pipe...

Also I already hit 180 Y/U for Cuprium for this version - for Yazhen & THIS...

I *think* I found a decent spot where I can alternate what I do without the resources flatout running out while I'm AFK, even for a day or two...? Maybe, maybe... still a bummer we didn't even get a couple more Cuprium nodes in the very last areas...

It's not optimal, but it's incredibly easy to modify/troubleshoot, which I prioritize. #ArknightsEndfield

Honestly I’m disappointed in how small this AIC event is, one whole week of putting xiranite and cuprium through a couple machines isn’t much of an event. It’s the second factory event and it doesn’t feel like it expanded on the first in any way.
September 18, 2026 at 8:32 PM
i don't know what to do with this area tbh, because the batteries need the sewage you make from cuprium processing so you have to do them in the same map. only resources left over are 2 loads of ferrium which can't make anything tradeable. guess in the future you could just make xiranite or somethin
March 12, 2026 at 3:21 PM
With the new gas stuff, I was able to tidy up my main AIC old battery line & transfer it, along with all the Xiranite, to Jingyu Valley. Also removed the separate sandleaf lines in Marker Stone & transferred my Cuprium production there.

Made an absolutely criminally messy setup for the new cuprium syringes and batteries.

I figured it was best to come up with *something* that worked, no matter how ugly, then figure out how to optimize it later.
March 15, 2026 at 3:01 AM
With the new area release, they finally provided us with the Cuprium needed for a stable Hetonite line & gave atleast one small originium deposit so I finally updated & stabilize my factory stuff a bit...

Still no additional ferrium deposit though...

I hope this new endfield map has more cuprium. The bump in forges means that I once again have an excess of xiranite to work with.

Need more ores so that I can make batteries and other things to put them in.
