Heavy Wolfram Helm ★★★

Taken all the way down to base materials, one Heavy Wolfram Helm is 3 crafting steps deep and needs 5 intermediates — Terminus Putty ×2, Darksteel Plate ×1, Darksteel Rings ×1 and 2 others — which resolve to 6 distinct raw materials totalling 16 units, plus 24 crystals.

That bill outweighs 6,959 of the 13,602 recipes tracked here and 642 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 21 are burned by the intermediates, so the real crystal cost is 9 Fire Crystal, 6 Ice Crystal, 2 Earth Cluster and 4 other kinds.

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

3 of the 6 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.

Of the intermediates, Darksteel Nugget has the widest use: 121 recipes call for it, spanning seven of the eight crafting classes.
