Horde Barding ★★★

Taken all the way down to base materials, one Horde Barding is 3 crafting steps deep and needs 4 intermediates — Eikon Leather ×4, Eikon Iron Ingot ×1, Griffin Leather Strap ×1 and 1 other — which resolve to 9 distinct raw materials totalling 48 units, plus 60 crystals.

That bill outweighs 12,691 of the 13,602 recipes tracked here and 1,815 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 55 are burned by the intermediates, so the real crystal cost is 15 Earth Cluster, 13 Wind Cluster, 8 Lightning Cluster and 4 other kinds.

The chain crosses three disciplines — Leatherworker to Lv 60, Alchemist to Lv 60 and Goldsmith to Lv 60 — so no single class can finish it unaided.

5 of the 9 raw materials come out of the ground, and 2 of them are time-gated: Smithsonite Ore (8:00, 20:00) and Wattle Bark (2:00, 14:00). The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Eikon Iron Ingot has the widest use: 140 recipes call for it, spanning seven of the eight crafting classes.
