Serpentskin Gloves of Healing

Taken all the way down to base materials, one Serpentskin Gloves of Healing is 2 crafting steps deep and needs 4 intermediates — Amphiptere Leather ×2, Aurum Regis Nugget ×1, Crawler Silk ×1 and 1 other — which resolve to 10 distinct raw materials totalling 27 units, plus 27 crystals.

That bill outweighs 9,763 of the 13,602 recipes tracked here and 1,384 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 10 Earth Crystal, 5 Lightning Crystal, 5 Wind Crystal and 3 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 59, Goldsmith to Lv 58, Weaver to Lv 57 and Alchemist to Lv 54 — so no single class can finish it unaided.

7 of the 10 raw materials come out of the ground, and 3 of them are time-gated: Gold Ore (9:00), Silkworm Cocoon (1:00) and 1 other. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Aurum Regis Nugget has the widest use: 185 recipes call for it, spanning seven of the eight crafting classes.
