Queen's Knight Barding ★★

Taken all the way down to base materials, one Queen's Knight Barding is 2 crafting steps deep and needs 3 intermediates — Maraging Steel Ingot ×2, Ra'Kaznar Ingot ×2 and Sterling Silver Ingot ×1 — which resolve to 7 distinct raw materials totalling 31 units, plus 40 crystals.

That bill outweighs 10,578 of the 13,602 recipes tracked here and 1,120 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 34 are burned by the intermediates, so the real crystal cost is 16 Fire Crystal, 9 Earth Cluster, 9 Fire Cluster and 2 other kinds.

The chain crosses three disciplines — Armorer to Lv 100, Blacksmith to Lv 100 and Goldsmith to Lv 100 — so no single class can finish it unaided.

4 of the 7 raw materials come out of the ground, and 2 of them are time-gated: Fine Silver Ore (10:00, 22:00) and Harmonite Ore (6:00, 18:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Ra'Kaznar Ingot has the widest use: 166 recipes call for it, spanning seven of the eight crafting classes.
