Archeo Kingdom Cuirass of Fending ★★

Taken all the way down to base materials, one Archeo Kingdom Cuirass of Fending is 2 crafting steps deep and needs 4 intermediates — Maraging Steel Ingot ×3, Blackseed Cotton Cloth ×2, Grade 2 Gemsap of Vitality ×2 and 1 other — which resolve to 11 distinct raw materials totalling 40 units, plus 50 crystals.

That bill outweighs 11,825 of the 13,602 recipes tracked here and 1,258 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 44 are burned by the intermediates, so the real crystal cost is 12 Earth Cluster, 9 Fire Cluster, 9 Lightning Cluster and 4 other kinds.

The chain crosses five disciplines — Armorer to Lv 100, Alchemist to Lv 100, Blacksmith to Lv 100, Weaver to Lv 100 and Leatherworker to Lv 98 — so no single class can finish it unaided.

6 of the 11 raw materials come out of the ground, and 3 of them are time-gated: Blackseed Cotton Boll (4:00, 16:00), Harmonite Ore (6:00, 18:00) and 1 other. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Gargantua Leather has the widest use: 89 recipes call for it, spanning five of the eight crafting classes.
