Wyvernskin Boots of Scouting

Taken all the way down to base materials, one Wyvernskin Boots of Scouting is 3 crafting steps deep and needs 7 intermediates — Wyvern Leather ×2, Mythrite Rivets ×1, Rainbow Cloth ×1 and 4 others — which resolve to 8 distinct raw materials totalling 22 units, plus 24 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 1,157 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 17 are burned by the intermediates, so the real crystal cost is 10 Earth Crystal, 6 Fire Crystal, 3 Lightning Crystal and 3 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 53, Blacksmith to Lv 51, Weaver to Lv 51 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 one of them is time-gated: Coerthan Tea Leaves (0:00, 8:00, 10:00, 12:00, 20:00, 22:00). 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.
