Classical Torquetum ★★

Taken all the way down to base materials, one Classical Torquetum is 3 crafting steps deep and needs 5 intermediates — Rhodium Ingot ×3, Grade 6 Mind Alkahest ×2, Lunar Adamantite Ingot ×2 and 2 others — which resolve to 11 distinct raw materials totalling 42 units, plus 58 crystals.

That bill outweighs 12,044 of the 13,602 recipes tracked here and 1,940 of the 2,216 Goldsmith 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 18 Fire Cluster, 16 Wind Crystal, 12 Wind Cluster and 3 other kinds.

The chain crosses three disciplines — Goldsmith to Lv 90, Alchemist to Lv 90 and Blacksmith to Lv 90 — so no single class can finish it unaided.

7 of the 11 raw materials come out of the ground, and 3 of them are time-gated: Double-edged Herb (10:00, 22:00), Lunar Adamantite Ore (2:00, 14:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Star Quartz has the widest use: 157 recipes call for it, spanning seven of the eight crafting classes.
