Shinryu's Wing ★★

Taken all the way down to base materials, one Shinryu's Wing is 3 crafting steps deep and needs 6 intermediates — Chromite Ingot ×1, Palladium Ingot ×1, Rhea Cloth ×1 and 3 others — which resolve to 12 distinct raw materials totalling 33 units, plus 29 crystals.

That bill outweighs 10,907 of the 13,602 recipes tracked here and 1,397 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 5 Fire Crystal, 5 Lightning Cluster, 5 Wind Crystal and 5 other kinds.

The chain crosses four disciplines — Alchemist to Lv 70, Blacksmith to Lv 70, Goldsmith to Lv 70 and Weaver to Lv 70 — so no single class can finish it unaided.

8 of the 12 raw materials come out of the ground, and 3 of them are time-gated: Chromite Ore (10:00, 22:00), Palladium Ore (4:00, 16:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Palladium Nugget has the widest use: 129 recipes call for it, spanning seven of the eight crafting classes.
