Seiryu's Sanctified Revolver ★★

Taken all the way down to base materials, one Seiryu's Sanctified Revolver is 3 crafting steps deep and needs 4 intermediates — Chromite Ingot ×3, Rhea Cloth ×2, Molybdenum Ingot ×5 and 1 other — which resolve to 9 distinct raw materials totalling 65 units, plus 60 crystals.

That bill outweighs 13,230 of the 13,602 recipes tracked here and 1,850 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 46 are burned by the intermediates, so the real crystal cost is 32 Fire Crystal, 7 Earth Crystal, 6 Earth Cluster and 4 other kinds.

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

5 of the 9 raw materials come out of the ground, and 2 of them are time-gated: Chromite Ore (10:00, 22:00) and Rhea (0:00, 12:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Chromite Ingot has the widest use: 121 recipes call for it, spanning six of the eight crafting classes.
