Suzaku Barding ★★★★

Taken all the way down to base materials, one Suzaku Barding is 4 crafting steps deep and needs 7 intermediates — Nightsteel Ingot ×2, Silvergrace Ingot ×2, Marid Leather ×1 and 4 others — which resolve to 12 distinct raw materials totalling 36 units, plus 31 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 4 of those crystals go into the final step; the other 27 are burned by the intermediates, so the real crystal cost is 6 Fire Crystal, 5 Earth Crystal, 5 Water Crystal and 5 other kinds.

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

8 of the 12 raw materials come out of the ground, and 2 of them are time-gated: Nightsteel Ore (6:00, 18:00) and Silvergrace Ore (8:00, 20:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, High Steel Nugget has the widest use: 133 recipes call for it, spanning seven of the eight crafting classes.
