Dragonskin Gloves of Casting

Taken all the way down to base materials, one Dragonskin Gloves of Casting is 2 crafting steps deep and needs 4 intermediates — Dragon Leather ×2, Dhalmel Leather ×1, Grade 1 Intelligence Dissolvent ×1 and 1 other — which resolve to 8 distinct raw materials totalling 24 units, plus 29 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 9 of those crystals go into the final step; the other 20 are burned by the intermediates, so the real crystal cost is 19 Earth Crystal, 4 Water Crystal, 4 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 56, Alchemist to Lv 54 and Weaver to Lv 54 — so no single class can finish it unaided.

5 of the 8 raw materials come out of the ground, and one of them is time-gated: Volcanic Rock Salt (17:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Dhalmel Leather has the widest use: 106 recipes call for it, spanning seven of the eight crafting classes.
