Zonureskin Jacket of Crafting

Taken all the way down to base materials, one Zonureskin Jacket of Crafting is 4 crafting steps deep and needs 5 intermediates — Zonure Leather ×2, Ovim Wool ×1, Titanbronze Nugget ×1 and 2 others — which resolve to 7 distinct raw materials totalling 27 units, plus 59 crystals.

That bill outweighs 9,763 of the 13,602 recipes tracked here and 1,384 of the 1,844 Leatherworker ones, and 1 recipe nests deeper.

Only 14 of those crystals go into the final step; the other 45 are burned by the intermediates, so the real crystal cost is 21 Earth Crystal, 14 Water Crystal, 14 Wind Crystal and 1 other kind.

The chain crosses four disciplines — Leatherworker to Lv 77, Alchemist to Lv 76, Goldsmith to Lv 76 and Weaver to Lv 76 — 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: Ala Mhigan Salt Crystal (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Titanbronze Nugget has the widest use: 72 recipes call for it, spanning seven of the eight crafting classes.
