Shinryu's Ephemeral Greatbow ★★

Taken all the way down to base materials, one Shinryu's Ephemeral Greatbow is 3 crafting steps deep and needs 4 intermediates — Chromite Ingot ×3, Palladium Nugget ×2, Torreya Lumber ×2 and 1 other — which resolve to 10 distinct raw materials totalling 61 units, plus 49 crystals.

That bill outweighs 13,148 of the 13,602 recipes tracked here and 1,815 of the 1,932 Blacksmith 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 15 Fire Crystal, 10 Wind Crystal, 8 Earth Cluster and 3 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 70, Carpenter to Lv 70 and Goldsmith to Lv 68 — so no single class can finish it unaided.

6 of the 10 raw materials come out of the ground, and 2 of them are time-gated: Chromite Ore (10:00, 22:00) and Torreya Log (6:00, 18:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

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