Jinrikisha

Taken all the way down to base materials, one Jinrikisha is 3 crafting steps deep and needs 4 intermediates — Manganese Ingot ×7, Twinsilk ×7, Ebony Lumber ×4 and 1 other — which resolve to 6 distinct raw materials totalling 121 units, plus 171 crystals.

That bill outweighs 13,515 of the 13,602 recipes tracked here and 1,926 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 64 of those crystals go into the final step; the other 107 are burned by the intermediates, so the real crystal cost is 88 Fire Crystal, 35 Lightning Crystal, 32 Earth Crystal and 2 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 90, Weaver to Lv 68 and Carpenter to Lv 50 — so no single class can finish it unaided.

5 of the 6 raw materials come out of the ground, and one of them is time-gated: Ebony Log (4:00). That window comes round once per Eorzean day, every 70 real-world minutes.

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