Serpentskin Shoes

Taken all the way down to base materials, one Serpentskin Shoes is 2 crafting steps deep and needs 4 intermediates — Amphiptere Leather ×2, Crawler Silk ×1, Dragon Leather ×1 and 1 other — which resolve to 7 distinct raw materials totalling 19 units, plus 24 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 958 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 21 are burned by the intermediates, so the real crystal cost is 15 Earth Crystal, 5 Lightning Crystal, 2 Earth Cluster and 2 other kinds.

The chain crosses three disciplines — Leatherworker to Lv 60, Weaver to Lv 57 and Alchemist to Lv 7 — so no single class can finish it unaided.

4 of the 7 raw materials come out of the ground, and one of them is time-gated: Silkworm Cocoon (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

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