Augmented Wolfram Cuirass ★★★

Taken all the way down to base materials, one Augmented Wolfram Cuirass is 4 crafting steps deep and needs 8 intermediates — Wolfram Square ×2, Wolfram Cuirass ×1, Terminus Putty ×2 and 5 others — which resolve to 12 distinct raw materials totalling 39 units, plus 36 crystals.

That bill outweighs 11,756 of the 13,602 recipes tracked here and 1,247 of the 1,441 Armorer ones, and 1 recipe nests deeper.

Only 3 of those crystals go into the final step; the other 33 are burned by the intermediates, so the real crystal cost is 8 Ice Cluster, 6 Earth Cluster, 6 Fire Crystal and 6 other kinds.

The chain crosses five disciplines — Armorer to Lv 50, Alchemist to Lv 50, Blacksmith to Lv 50, Goldsmith to Lv 50 and Leatherworker to Lv 50 — so no single class can finish it unaided.

6 of the 12 raw materials come out of the ground, and 3 of them are time-gated: Darksteel Ore (1:00), Ferberite (3:00) and 1 other. The widest gap between consecutive opening times is 16 Eorzean hours, about 47 real-world minutes.

Of the intermediates, Rose Gold Nugget has the widest use: 179 recipes call for it, spanning seven of the eight crafting classes.
