Neo-Ishgardian Gloves of Scouting ★★★

Taken all the way down to base materials, one Neo-Ishgardian Gloves of Scouting is 3 crafting steps deep and needs 5 intermediates — Cobalt Alloy Ingot ×2, Grade 3 Dexterity Alkahest ×2, Dwarven Cotton ×1 and 2 others — 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 1,028 of the 1,441 Armorer ones, and 337 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 Lightning Crystal, 4 Fire Cluster and 4 other kinds.

The chain crosses five disciplines — Armorer to Lv 80, Alchemist to Lv 80, Blacksmith to Lv 80, Leatherworker to Lv 80 and Weaver 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, Dwarven Cotton has the widest use: 165 recipes call for it, spanning eight of the eight crafting classes.
