Serpentskin Helm of Maiming

Taken all the way down to base materials, one Serpentskin Helm of Maiming is 2 crafting steps deep and needs 3 intermediates — Amphiptere Leather ×2, Aurum Regis Nugget ×2 and Grade 1 Strength Dissolvent ×1 — which resolve to 7 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, 10 Wind Crystal, 4 Water Crystal and 2 other kinds.

The chain crosses three disciplines — Leatherworker to Lv 60, Goldsmith to Lv 58 and Alchemist to Lv 53 — so no single class can finish it unaided.

4 of the 7 raw materials come out of the ground, and 2 of them are time-gated: Gold Ore (9:00) and Volcanic Rock Salt (17:00). The widest gap between consecutive opening times is 16 Eorzean hours, about 47 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.
