Eternal Barding ★

Taken all the way down to base materials, one Eternal Barding is 3 crafting steps deep and needs 4 intermediates — Black Star ×2, Maraging Steel Ingot ×2, Sterling Silver Ingot ×1 and 1 other — which resolve to 7 distinct raw materials totalling 33 units, plus 56 crystals.

That bill outweighs 10,907 of the 13,602 recipes tracked here and 1,153 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 50 are burned by the intermediates, so the real crystal cost is 16 Water Crystal, 16 Wind Crystal, 9 Earth Cluster and 3 other kinds.

The chain crosses four disciplines — Armorer to Lv 100, Blacksmith to Lv 100, Goldsmith to Lv 100 and Alchemist to Lv 95 — 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, Black Star has the widest use: 161 recipes call for it, spanning six of the eight crafting classes.
