Classical Signifer's Horns ★★

Taken all the way down to base materials, one Classical Signifer's Horns is 3 crafting steps deep and needs 5 intermediates — Grade 6 Intelligence Alkahest ×2, Rhodium Ingot ×2, Amynodon Leather ×1 and 2 others — which resolve to 11 distinct raw materials totalling 30 units, plus 46 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,694 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 16 Wind Crystal, 12 Wind Cluster, 9 Fire Cluster and 3 other kinds.

The chain crosses three disciplines — Goldsmith to Lv 90, Alchemist to Lv 90 and Leatherworker 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), Rhodium Sand (4:00, 16:00) 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.
