Gliderskin Thighboots of Fending

Taken all the way down to base materials, one Gliderskin Thighboots of Fending is 3 crafting steps deep and needs 5 intermediates — Green Glider Leather ×2, Iridescent Silk ×1, Rubber ×1 and 2 others — which resolve to 6 distinct raw materials totalling 19 units, plus 34 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 958 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 22 are burned by the intermediates, so the real crystal cost is 18 Earth Crystal, 9 Lightning Crystal, 6 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 73, Weaver to Lv 72 and Alchemist to Lv 7 — so no single class can finish it unaided.

5 of the 6 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.
