If you keep running into blocked tunnels, laser grids, and "come back later" routes in Endfield, you're not doing anything wrong—you're just missing Industrial Explosives, and that's where Arknights endfield boosting can be a handy reference point while you're sorting out progression. A lot of players assume explosives are a random drop. They aren't. You've got to build the chain and unlock the right tech first, or you'll be staring at a locked recipe forever.

Unlock The Right Tech First

Before you even think about materials, check your AIC Factory Plan. You need Packaging Tech under Basic AIC II, and if it's greyed out, you're probably not done with the "Paving the Way" main quest. Finish that, then spend a Basic Expansion Core to finalize the unlock. After that, head to your Temporary Shelter and place a Packaging Unit. Try to keep it close to your Sub-PAC so you're not sprinting back and forth every time you queue something up.

Build The Full Production Line

The Packaging Unit is just the last stop. You'll also need a Refining Unit, a Fitting Unit, and a Shredding Unit to actually turn raw finds into usable ingredients. If you're missing any of those, comb the Core AIC Area in The Hub and grab what you need. Then do the boring-but-critical step: power. Connect every machine to an Electric Pylon. People forget one cable, nothing runs, and you lose ten minutes wondering why the queue won't start.

Farm Amethyst And Aketine Without Wasting Time

For Amethyst Ores, Bridge Pass in The Hub is usually the quickest loop. Mine until you're full, then bring it home and process it in order: Ores go into the Refining Unit for Amethyst Fibre, then that Fibre goes into the Fitting Unit to become Amethyst Parts. Aketine is the other piece, and it's more annoying. Valley Pass is the most consistent spot I've had—fast travel to the Temporary Shelter, head east, and check the bushes along the path. Once you've got Aketine, drop it into the Shredding Unit and turn it into Aketine Powder.

Craft The Explosives And Break Through

Now you're set: the Packaging Unit recipe takes 5 Amethyst Parts and 1 Aketine Powder, and it finishes fast—around ten seconds once everything's powered and linked properly.
