Wyvernskin Boots of Striking

Taken all the way down to base materials, one Wyvernskin Boots of Striking is 3 crafting steps deep and needs 5 intermediates — Wyvern Leather ×2, Archaeornis Leather ×1, Mythrite Rivets ×1 and 2 others — which resolve to 6 distinct raw materials totalling 19 units, plus 23 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 7 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 13 Earth Crystal, 6 Fire Crystal, 3 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 53, Blacksmith to Lv 51 and Alchemist to Lv 7 — so no single class can finish it unaided.

4 of the 6 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.
