Shinryu Barding ★★

Taken all the way down to base materials, one Shinryu Barding is 3 crafting steps deep and needs 5 intermediates — Chromite Ingot ×2, Gazelle Leather ×1, Palladium Nugget ×1 and 2 others — which resolve to 10 distinct raw materials totalling 47 units, plus 47 crystals.

That bill outweighs 12,643 of the 13,602 recipes tracked here and 1,331 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 43 are burned by the intermediates, so the real crystal cost is 20 Fire Crystal, 6 Earth Cluster, 5 Earth Crystal and 4 other kinds.

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

7 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.
