Seiryu's Sanctified Cane ★★

Taken all the way down to base materials, one Seiryu's Sanctified Cane is 3 crafting steps deep and needs 4 intermediates — Palladium Ingot ×3, Rhodonite ×2, True Griffin Leather ×2 and 1 other — which resolve to 11 distinct raw materials totalling 59 units, plus 61 crystals.

That bill outweighs 13,079 of the 13,602 recipes tracked here and 2,117 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 47 are burned by the intermediates, so the real crystal cost is 34 Wind Crystal, 10 Wind Cluster, 7 Fire Crystal and 2 other kinds.

The chain crosses two disciplines — Goldsmith to Lv 70 and Leatherworker to Lv 70 — so no single class can finish it unaided.

6 of the 11 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.
