Wyvernskin Mane of Fending

Taken all the way down to base materials, one Wyvernskin Mane of Fending is 3 crafting steps deep and needs 3 intermediates — Tiger's Eye ×2, Wyvern Leather ×2 and Basilisk Whetstone ×2 — which resolve to 5 distinct raw materials totalling 20 units, plus 29 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 1,025 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 22 are burned by the intermediates, so the real crystal cost is 10 Earth Crystal, 10 Wind Shard and 9 Wind Crystal.

The chain crosses two disciplines — Leatherworker to Lv 53 and Goldsmith to Lv 51 — so no single class can finish it unaided.

3 of the 5 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, Wyvern Leather has the widest use: 62 recipes call for it, spanning six of the eight crafting classes.
