Onishi Zori ★★★

Taken all the way down to base materials, one Onishi Zori is 3 crafting steps deep and needs 4 intermediates — Ground Sloth Leather ×6, Veteran Tree Sap ×2, Worsted Yarn ×1 and 1 other — which resolve to 10 distinct raw materials totalling 38 units, plus 28 crystals.

That bill outweighs 11,698 of the 13,602 recipes tracked here and 1,745 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 8 Earth Cluster, 8 Wind Cluster, 4 Lightning Cluster and 3 other kinds.

The chain crosses three disciplines — Leatherworker to Lv 70, Alchemist to Lv 70 and Weaver to Lv 66 — so no single class can finish it unaided.

3 of the 10 raw materials come out of the ground, and one of them is time-gated: Hardened Veteran Tree Sap (4:00, 16:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Worsted Yarn has the widest use: 66 recipes call for it, spanning three of the eight crafting classes.
