Heavy Wolfram Cuirass ★★★

Taken all the way down to base materials, one Heavy 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 8 distinct raw materials totalling 21 units, plus 30 crystals.

That bill outweighs 8,152 of the 13,602 recipes tracked here and 780 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 27 are burned by the intermediates, so the real crystal cost is 9 Fire Crystal, 6 Ice Crystal, 4 Fire Cluster and 5 other kinds.

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

4 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Darksteel Ore (1:00) and Ferberite (3:00). The widest gap between consecutive opening times is 22 Eorzean hours, about 64 real-world minutes.

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