Manganese File

Taken all the way down to base materials, one Manganese File is 2 crafting steps deep and needs 2 intermediates — Manganese Ingot ×3 and Scarlet Moko Cloth ×1 — which resolve to 3 distinct raw materials totalling 23 units, plus 48 crystals.

That bill outweighs 8,647 of the 13,602 recipes tracked here and 956 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 32 Fire Crystal, 8 Earth Crystal and 8 Lightning Crystal.

The chain crosses two disciplines — Blacksmith to Lv 87 and Weaver to Lv 86 — so no single class can finish it unaided.

All 3 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

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