Wyvernskin Workboots

Taken all the way down to base materials, one Wyvernskin Workboots is 4 crafting steps deep and needs 7 intermediates — Wyvern Leather ×2, Holy Rainbow Cloth ×1, Rubber ×1 and 4 others — which resolve to 8 distinct raw materials totaling 25 units, plus 25 crystals.

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

Only 7 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 10 Earth Crystal, 7 Lightning Crystal, 3 Water Crystal and 3 other kinds.

The chain crosses three disciplines — Leatherworker to Lv 53, Alchemist to Lv 52 and Weaver to Lv 52 — 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 (10:00, 22:00) and Dravanian Mistletoe (0:00, 12:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

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