Ebony Staff ★★★★

Taken all the way down to base materials, one Ebony Staff is 2 crafting steps deep and needs 3 intermediates — Ebony Lumber ×3, Platinum Ingot ×2 and Iolite ×1 — which resolve to 8 distinct raw materials totalling 63 units, plus 27 crystals.

That bill outweighs 13,204 of the 13,602 recipes tracked here and 1,434 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 14 Wind Cluster, 8 Ice Cluster and 5 Fire Cluster.

The chain crosses two disciplines — Carpenter to Lv 50 and Goldsmith to Lv 50 — so no single class can finish it unaided.

3 of the 8 raw materials come out of the ground, and 3 of them are time-gated: Ebony Log (4:00), Platinum Ore (4:00) and 1 other. The widest gap between consecutive opening times is 23 Eorzean hours, about 67 real-world minutes.

Of the intermediates, Platinum Ingot has the widest use: 176 recipes call for it, spanning seven of the eight crafting classes.
