Serpentskin Halfgloves of Crafting

Taken all the way down to base materials, one Serpentskin Halfgloves of Crafting is 2 crafting steps deep and needs 2 intermediates — Amphiptere Leather ×2 and Crawler Silk ×1 — which resolve to 5 distinct raw materials totalling 14 units, plus 18 crystals.

That bill outweighs 6,557 of the 13,602 recipes tracked here and 807 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 15 are burned by the intermediates, so the real crystal cost is 10 Earth Crystal, 5 Lightning Crystal, 2 Earth Cluster and 1 other kind.

The chain crosses two disciplines — Leatherworker to Lv 59 and Weaver to Lv 57 — so no single class can finish it unaided.

3 of the 5 raw materials come out of the ground, and one of them is time-gated: Silkworm Cocoon (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Crawler Silk has the widest use: 178 recipes call for it, spanning five of the eight crafting classes.
