Factory Pillar

Taken all the way down to base materials, one Factory Pillar is 2 crafting steps deep and needs 2 intermediates — Bismuth Ingot ×7 and Manganese Ingot ×7 — which resolve to 5 distinct raw materials totalling 85 units, plus 128 crystals.

That bill outweighs 13,425 of the 13,602 recipes tracked here and 1,916 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 112 are burned by the intermediates, so the real crystal cost is 120 Fire Crystal and 8 Earth Crystal.

Every step is Blacksmith work, from a Lv 84 intermediate up to the Lv 90 finish, so one class covers the whole chain.

4 of the 5 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Of the intermediates, Manganese Ingot has the widest use: 134 recipes call for it, spanning seven of the eight crafting classes.
