Neo-Ishgardian Gloves of Casting ★★★

Taken all the way down to base materials, one Neo-Ishgardian Gloves of Casting is 2 crafting steps deep and needs 4 intermediates — Cobalt Alloy Ingot ×2, Grade 3 Intelligence Alkahest ×2, Duskcourt Cloth ×1 and 1 other — which resolve to 11 distinct raw materials totalling 30 units, plus 27 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,081 of the 1,441 Armorer 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 7 Earth Crystal, 6 Earth Cluster, 4 Fire Cluster and 4 other kinds.

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

5 of the 11 raw materials come out of the ground, and 3 of them are time-gated: Duskblooms (4:00, 16:00), 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, Sea Swallow Leather has the widest use: 124 recipes call for it, spanning six of the eight crafting classes.
