Serpentskin Hat of Casting

Taken all the way down to base materials, one Serpentskin Hat of Casting is 4 crafting steps deep and needs 8 intermediates — Amphiptere Leather ×2, Grade 1 Intelligence Dissolvent ×1, Hallowed Ramie Cloth ×1 and 5 others — which resolve to 11 distinct raw materials totalling 30 units, plus 43 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,521 of the 1,844 Leatherworker ones, and 1 recipe nests deeper.

Only 10 of those crystals go into the final step; the other 33 are burned by the intermediates, so the real crystal cost is 15 Earth Crystal, 9 Lightning Crystal, 9 Water Crystal and 2 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 58, Alchemist to Lv 56, Weaver to Lv 56 and Goldsmith to Lv 50 — so no single class can finish it unaided.

9 of the 11 raw materials come out of the ground, and 3 of them are time-gated: Abalathian Mistletoe (6:00, 18:00), Gold Ore (9:00) and 1 other. The widest gap between consecutive opening times is 12 Eorzean hours, about 35 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.
