Heavy Metal Lance ★★★★

Taken all the way down to base materials, one Heavy Metal Lance is 3 crafting steps deep and needs 6 intermediates — Heavy Metal Ingot ×2, Saurian Leather ×2, Teak Lumber ×2 and 3 others — which resolve to 16 distinct raw materials totalling 79 units, plus 58 crystals.

That bill outweighs 13,405 of the 13,602 recipes tracked here and 1,481 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 52 are burned by the intermediates, so the real crystal cost is 19 Fire Cluster, 16 Wind Cluster, 14 Earth Cluster and 1 other kind.

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

7 of the 16 raw materials come out of the ground, and 6 of them are time-gated: Luminium Ore (6:00, 18:00), Teak Log (0:00, 12:00) and 4 others. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

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