Byakko's Enspirited Rod ★★

Taken all the way down to base materials, one Byakko's Enspirited Rod is 3 crafting steps deep and needs 5 intermediates — Palladium Ingot ×3, Chromite Ingot ×2, Rhodonite ×2 and 2 others — which resolve to 12 distinct raw materials totalling 69 units, plus 71 crystals.

That bill outweighs 13,278 of the 13,602 recipes tracked here and 2,146 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 57 are burned by the intermediates, so the real crystal cost is 34 Wind Crystal, 17 Fire Crystal, 10 Fire Cluster and 2 other kinds.

The chain crosses two disciplines — Goldsmith to Lv 70 and Blacksmith 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.
