Hades Barding ★★

Taken all the way down to base materials, one Hades Barding is 3 crafting steps deep and needs 4 intermediates — Tungsten Steel Ingot ×2, Dwarven Cotton ×1, Dwarven Mythril Nugget ×1 and 1 other — which resolve to 6 distinct raw materials totalling 22 units, plus 122 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 808 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 100 of those crystals go into the final step; the other 22 are burned by the intermediates, so the real crystal cost is 50 Earth Crystal, 50 Ice Crystal, 7 Lightning Crystal and 3 other kinds.

The chain crosses four disciplines — Armorer to Lv 80, Blacksmith to Lv 80, Goldsmith to Lv 78 and Weaver to Lv 78 — so no single class can finish it unaided.

4 of the 6 raw materials come out of the ground, and one of them is time-gated: Tungsten Ore (10:00, 22:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Dwarven Cotton has the widest use: 165 recipes call for it, spanning eight of the eight crafting classes.
