Replica Allagan Cuirass of Striking ★★

Taken all the way down to base materials, one Replica Allagan Cuirass of Striking is 2 crafting steps deep and needs 3 intermediates — Arachne Velveteen ×2, Wootz Ingot ×2 and Platinum Ingot ×1 — which resolve to 8 distinct raw materials totalling 24 units, plus 24 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 881 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 20 are burned by the intermediates, so the real crystal cost is 6 Earth Cluster, 6 Fire Cluster, 6 Wind Cluster and 2 other kinds.

The chain crosses four disciplines — Armorer to Lv 60, Blacksmith to Lv 50, Goldsmith to Lv 50 and Weaver to Lv 50 — so no single class can finish it unaided.

1 of the 8 raw materials come out of the ground, and one of them is time-gated: Platinum Ore (4:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Platinum Ingot has the widest use: 176 recipes call for it, spanning seven of the eight crafting classes.
