Shinryu's Ephemeral Rod ★★

Taken all the way down to base materials, one Shinryu's Ephemeral Rod is 3 crafting steps deep and needs 3 intermediates — Palladium Ingot ×3, Torreya Lumber ×2 and Palladium Nugget ×5 — which resolve to 8 distinct raw materials totalling 61 units, plus 49 crystals.

That bill outweighs 13,148 of the 13,602 recipes tracked here and 2,129 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 45 are burned by the intermediates, so the real crystal cost is 25 Wind Crystal, 12 Wind Cluster, 8 Fire Cluster and 1 other kind.

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

4 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Palladium Ore (4:00, 16:00) and Torreya Log (6:00, 18:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

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