Yamashi Zori ★★★

Taken all the way down to base materials, one Yamashi Zori is 3 crafting steps deep and needs 5 intermediates — Ground Sloth Leather ×6, Veteran Tree Sap ×2, Rubber ×1 and 2 others — which resolve to 11 distinct raw materials totalling 39 units, plus 29 crystals.

That bill outweighs 11,756 of the 13,602 recipes tracked here and 1,756 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 25 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.

4 of the 11 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, Rubber has the widest use: 191 recipes call for it, spanning four of the eight crafting classes.
