Wolfram Cuirass ★★★

Taken all the way down to base materials, one Wolfram Cuirass is 3 crafting steps deep and needs 6 intermediates — Terminus Putty ×2, Wolfram Ingot ×2, Darksteel Plate ×1 and 3 others — which resolve to 10 distinct raw materials totalling 22 units, plus 27 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 808 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 6 Fire Crystal, 4 Fire Cluster, 3 Earth Cluster 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 10 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.

Wolfram Cuirass is itself consumed by 1 further recipe, all of them Armorer recipes.
