Classical Sagittarius's Chiton ★★

Taken all the way down to base materials, one Classical Sagittarius's Chiton is 2 crafting steps deep and needs 4 intermediates — Amynodon Leather ×3, Golden Silk ×2, Grade 6 Dexterity Alkahest ×2 and 1 other — which resolve to 11 distinct raw materials totalling 41 units, plus 50 crystals.

That bill outweighs 11,923 of the 13,602 recipes tracked here and 1,769 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 44 are burned by the intermediates, so the real crystal cost is 18 Wind Cluster, 12 Earth Cluster, 9 Lightning Cluster and 2 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 90, Alchemist to Lv 90, Weaver to Lv 90 and Blacksmith to Lv 88 — 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), Golden Cocoon (8:00, 20:00) 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.
