A BAB with Big Depot hats, filtered and belted appropriately to collect *all 60 Dark Fog drops* and feed them out to individual, labeled belts. Impossible to clog; an overload on one belt will just stop the BAB from collecting that one item.
* Uses Big Depot, Mk3 Conveyor, Mk3 Sorter.
* Requires Vertical Construction 5 (the last one that needs yellow science). No purple or green science required.
* At the moment, some items dropped by level 15+ bases aren't set correctly in the depot/sorter filters, because I don't have access to them yet in my game! They're, instead, set to blue cubes (which can't drop, so they'll stay empty). A future update will correct all of them, but it's easy to spot and fix them. The depot outputs are all sorted in the exact order the drop table uses (which you can view in the BAB UI), or you can trace back one of the output belt labels to figure out which sorter should filter for it, and change one of the depot filters to match.
* Recommended use is to either only pipe out the few items you want and ignore the rest, or, if you're crazy like me, set up five rings of 12 stacked belts (see the "additional pictures") so you can feed all 60 items in and pull them out individually to ILSes.
