Wyvernskin Boots of Casting

Taken all the way down to base materials, one Wyvernskin Boots of Casting is 3 crafting steps deep and needs 6 intermediates — Wyvern Leather ×2, Rainbow Cloth ×1, Rose Gold Nugget ×1 and 3 others — which resolve to 8 distinct raw materials totalling 25 units, plus 22 crystals.

That bill outweighs 9,313 of the 13,602 recipes tracked here and 1,283 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 15 are burned by the intermediates, so the real crystal cost is 10 Earth Crystal, 6 Wind Crystal, 4 Lightning Crystal and 2 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 53, Weaver to Lv 51, Goldsmith to Lv 50 and Alchemist to Lv 7 — so no single class can finish it unaided.

6 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Coerthan Tea Leaves (0:00, 8:00, 10:00, 12:00, 20:00, 22:00) and Gold Ore (9:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

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