Once you hit that level 18 to 34 stretch in Endfield, the game starts asking a different question. It's not whether you can win fights. It's whether your base can keep up. A lot of players waste time pushing combat nodes too hard when the smarter move is fixing the economy first, and if you're trying to save time while you build things out, some people even buy Arknights endfield boosting so they can focus more on the factory side of the game. Either way, this is the point where hand-feeding basic materials stops working. You need stable ore, stable power, and clean routing, or the whole mid-game starts feeling rough for no good reason.
Start with the right unlocks
The first step is simple. Stop spending every point on movement toys and side exploration. Ziplines are fun, sure, but they won't fix stalled production. Go after the systems that actually let your base breathe. Electric Mining Rig Mk II should be near the top of the list because Ferrium and Cuprium become essential almost right away. After that, Protocol Stash helps more than people expect. It lets you build tighter layouts, and that matters once your base gets crowded. Then grab Depot Bus for easier routing between sections, and pick up Thermal Banks early. Without extra capacity, your machines dip in and out of operation, and that kind of stop-start output wrecks efficiency.
Build around ore and power
Mid-game progression really comes down to two things: can you mine enough, and can you power what you mine. Ferrium and Cuprium sit at the centre of nearly every useful upgrade, especially once blue and purple equipment starts becoming the standard instead of a luxury. So don't spread your attention too thin. Put Electric Mining Rigs on every solid Ferrium node you've found and make sure the line feeding them is reliable. One setup that works well is running a single output through a double-splitter into four Thermal Banks. It's tidy, easy to maintain, and it smooths out power dips better than a messy grid. At the same time, start moving away from early Amethyst-dependent battery setups. SC Valley Batteries are just better value once your factory grows.
Keep the layout clean
A lot of base problems aren't really resource problems. They're layout problems. You'll notice it fast when belts start crossing everywhere and intermediate parts pile up for no reason. Using the top-down build view makes a huge difference, especially if you're trying to place long lines without wasting space. Caps Lock feels like a tiny trick, but it saves loads of time. Try to keep production chains close together and use Protocol Stashes to avoid sprawling lines. Also, don't fall into the habit of overbuilding one part just because you can. A one-to-one ratio is usually safer in this part of the game. It keeps flow steady and stops random choke points from appearing three steps later.
Make outposts do the heavy lifting
Outposts are easy to overlook, but they're one of the best ways to take pressure off your main base. Treat them like support hubs, not side content. When you fill their supply requests regularly, you earn Convention Certificates and push the region toward higher development states like Bustling or Prosperous. That extra yield adds up more than most players think. Before you spend big on upgrades, though, stash enough Ferrium and Amethyst components so you don't stall your main lines. It's also worth running a quiet background chain for healing items, because tougher stages burn through meds fast.
