Seiryu Barding ★★★★

Taken all the way down to base materials, one Seiryu Barding is 4 crafting steps deep and needs 7 intermediates — Chigusa Ingot ×2, Evergleam Ingot ×2, Gazelle Leather ×1 and 4 others — which resolve to 13 distinct raw materials totalling 36 units, plus 132 crystals.

That bill outweighs 11,383 of the 13,602 recipes tracked here and 1,196 of the 1,441 Armorer ones, and 1 recipe nests deeper.

Only 100 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 55 Earth Crystal, 50 Ice Crystal, 9 Fire Crystal and 5 other kinds.

The chain crosses five disciplines — Armorer to Lv 70, Blacksmith to Lv 70, Goldsmith to Lv 70, Leatherworker to Lv 68 and Alchemist to Lv 66 — so no single class can finish it unaided.

9 of the 13 raw materials come out of the ground, and 2 of them are time-gated: Evergleam Ore (10:00, 22:00) and Gyr Abanian Ore (0:00, 12:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

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