Seiryu's Sanctified Paladin Arms ★★

Taken all the way down to base materials, one Seiryu's Sanctified Paladin Arms is 3 crafting steps deep and needs 4 intermediates — Chromite Ingot ×3, Palladium Nugget ×2, True Griffin Leather ×2 and 1 other — which resolve to 10 distinct raw materials totalling 61 units, plus 59 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 14 of those crystals go into the final step; the other 45 are burned by the intermediates, so the real crystal cost is 22 Fire Crystal, 10 Earth Cluster, 10 Wind Crystal and 3 other kinds.

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

5 of the 10 raw materials come out of the ground, and one of them is time-gated: Chromite Ore (10:00, 22:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

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