Once you start roaming farther across Talos-II, it becomes obvious that the game loves putting rewards behind breakable walls and Blight Cores. That's usually the moment players realise they need a proper supply of Industrial Explosives, not just one or two picked up by chance. If you're trying to smooth out exploration and avoid getting stuck on side content, Arknights endfield boosting can sit alongside a solid factory setup, because the real key here is unlocking production early and keeping it running. You can't rush it from the opening hours, though. First, you need to progress the story far enough to obtain the Basic Expansion Core. After that, upgrading your base to Basic AIC Level II opens Packaging Technology, and that's the point where the Packaging Unit becomes available.
The recipe is refreshingly simple, which is probably why the game expects you to make loads of them. One Industrial Explosive needs 1 Aketine Powder and 5 Amethyst Parts. On paper, that doesn't sound bad at all. In practice, it means setting up two separate resource chains before the Packaging Unit can do anything useful. A lot of players hit this step and just hand-feed materials into the machine when they need a few bombs. It works, sure, but it gets old fast. Ten seconds per explosive doesn't feel long until you're standing there waiting for your fifth or sixth one because a hidden chest or quest marker sent you back across the map.
Aketine Powder is usually the first material people sort out, mostly because the raw plants are easy enough to recognise in Valley Pass. Early on, you'll probably gather them by hand. That's fine for a short while. Still, you'll very quickly notice how wasteful that feels once barriers start showing up more often. The better move is to make Aketine renewable. Set up Seed-Pickers, connect them to Planting Units, and route the harvested plants straight into a Shredding Unit. That gives you a reliable flow of powder without having to babysit every step. Once it's working, you can mostly forget about it and let the belts do the boring part.
The Amethyst side is a bit more industrial, but it's not hard once you lay it out cleanly. Start with Amethyst Ore from your mining spots. Feed that into a Refining Unit to produce Amethyst Fiber, then send the fiber to a Fitting Unit for Amethyst Parts. That's the full loop. The trick isn't understanding the recipe, it's making sure your lines don't choke. If power dips or your conveyors are messy, explosive production slows to a crawl. And when that happens, exploration gets annoying again. Keeping the Packaging Unit connected to both the shredded Aketine and fitted Amethyst Parts means you've got a steady stream of bombs ready in storage instead of crafting them one by one whenever the map asks for one.
Having a stockpile changes the feel of the whole mid-game. You stop marking blocked paths for later and just deal with them on the spot. Hidden rooms, puzzle objectives, tucked-away loot, side mission routes, all of it becomes easier when you're carrying enough explosives to not think twice. That's why players who invest in automation early tend to move through Talos-II with way less friction.
