Heavy Metal Claws ★★★★

Taken all the way down to base materials, one Heavy Metal Claws is 3 crafting steps deep and needs 6 intermediates — Heavy Metal Ingot ×3, Scintillant Ingot ×2, Ancient Lumber ×1 and 3 others — which resolve to 15 distinct raw materials totalling 78 units, plus 68 crystals.

That bill outweighs 13,397 of the 13,602 recipes tracked here and 1,909 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 62 are burned by the intermediates, so the real crystal cost is 34 Fire Cluster, 20 Earth Cluster, 13 Wind Cluster and 1 other kind.

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

7 of the 15 raw materials come out of the ground, and 6 of them are time-gated: Luminium Ore (6:00, 18:00), Tungstite (2:00, 14:00) and 4 others. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

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