Classical Dimachaerius's Caligae ★★

Taken all the way down to base materials, one Classical Dimachaerius's Caligae is 2 crafting steps deep and needs 4 intermediates — Grade 6 Dexterity Alkahest ×2, Lunar Adamantite Ingot ×2, Amynodon Leather ×1 and 1 other — which resolve to 11 distinct raw materials totalling 29 units, plus 38 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,028 of the 1,441 Armorer 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, 8 Fire Crystal, 6 Fire Cluster and 4 other kinds.

The chain crosses four disciplines — Armorer to Lv 90, Alchemist to Lv 90, Blacksmith 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), 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, Chondrite Ingot has the widest use: 210 recipes call for it, spanning seven of the eight crafting classes.
