Neo-Ishgardian Boots of Casting ★★★

Taken all the way down to base materials, one Neo-Ishgardian Boots of Casting is 2 crafting steps deep and needs 4 intermediates — Grade 3 Intelligence Alkahest ×2, Megalania Leather ×2, Cobalt Alloy Ingot ×1 and 1 other — which resolve to 10 distinct raw materials totalling 29 units, plus 27 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,478 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 8 Earth Cluster, 7 Wind Crystal, 6 Wind Cluster and 3 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 80, Alchemist to Lv 80, Blacksmith to Lv 80 and Carpenter to Lv 78 — so no single class can finish it unaided.

5 of the 10 raw materials come out of the ground, and 3 of them are time-gated: Ashen Alumen (10:00, 22:00), Fireheart Cobalt (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, Lignum Vitae Lumber has the widest use: 134 recipes call for it, spanning seven of the eight crafting classes.
