Archaeoskin Jackcoat of Crafting

Taken all the way down to base materials, one Archaeoskin Jackcoat of Crafting is 3 crafting steps deep and needs 5 intermediates — Archaeornis Leather ×3, Mythrite Nugget ×1, Rainbow Cloth ×1 and 2 others — which resolve to 7 distinct raw materials totalling 30 units, plus 23 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,521 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 17 are burned by the intermediates, so the real crystal cost is 12 Earth Crystal, 4 Lightning Crystal, 3 Fire Crystal and 2 other kinds.

The chain crosses three disciplines — Leatherworker to Lv 52, Blacksmith to Lv 51 and Weaver to Lv 51 — so no single class can finish it unaided.

5 of the 7 raw materials come out of the ground, and one of them is time-gated: Coerthan Tea Leaves (0:00, 8:00, 10:00, 12:00, 20:00, 22:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Rainbow Thread has the widest use: 116 recipes call for it, spanning five of the eight crafting classes.
