Gaganaskin Vest

Taken all the way down to base materials, one Gaganaskin Vest is 3 crafting steps deep and needs 4 intermediates — Bloodhempen Cloth ×2, Gagana Leather ×2, Rose Gold Nugget ×1 and 1 other — which resolve to 5 distinct raw materials totalling 24 units, plus 21 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 1,247 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 9 Earth Crystal, 7 Lightning Crystal and 5 Wind Crystal.

The chain crosses three disciplines — Leatherworker to Lv 61, Weaver to Lv 61 and Goldsmith to Lv 50 — so no single class can finish it unaided.

4 of the 5 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, Rose Gold Nugget has the widest use: 179 recipes call for it, spanning seven of the eight crafting classes.
