Swallowskin Gloves of Scouting

Taken all the way down to base materials, one Swallowskin Gloves of Scouting is 2 crafting steps deep and needs 4 intermediates — Sea Swallow Leather ×2, Dwarven Mythril Nugget ×1, Grade 1 Dexterity Alkahest ×1 and 1 other — which resolve to 9 distinct raw materials totalling 24 units, plus 47 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 1,247 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 33 are burned by the intermediates, so the real crystal cost is 21 Earth Crystal, 20 Wind Crystal and 6 Water Crystal.

The chain crosses three disciplines — Leatherworker to Lv 78, Goldsmith to Lv 78 and Alchemist to Lv 73 — so no single class can finish it unaided.

7 of the 9 raw materials come out of the ground, and one of them is time-gated: Gold Ore (9:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Dwarven Mythril Nugget has the widest use: 154 recipes call for it, spanning seven of the eight crafting classes.
