Classical Sagittarius's Caligae ★★

Taken all the way down to base materials, one Classical Sagittarius's Caligae is 2 crafting steps deep and needs 4 intermediates — Amynodon Leather ×2, Grade 6 Dexterity Alkahest ×2, Lunar Adamantite Ingot ×1 and 1 other — which resolve to 11 distinct raw materials totalling 28 units, plus 38 crystals.

That bill outweighs 9,936 of the 13,602 recipes tracked here and 1,414 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 12 Earth Cluster, 9 Wind Cluster, 8 Earth Crystal and 3 other kinds.

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

6 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 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Ophiotauros Leather has the widest use: 153 recipes call for it, spanning seven of the eight crafting classes.
