Serpentskin Bootlets of Casting

Taken all the way down to base materials, one Serpentskin Bootlets of Casting is 3 crafting steps deep and needs 6 intermediates — Amphiptere Leather ×2, Chimerical Felt ×1, Crawler Silk ×1 and 3 others — which resolve to 12 distinct raw materials totalling 30 units, plus 30 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,521 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 27 are burned by the intermediates, so the real crystal cost is 10 Earth Crystal, 10 Lightning Crystal, 4 Water Crystal and 3 other kinds.

The chain crosses three disciplines — Leatherworker to Lv 60, Weaver to Lv 58 and Alchemist to Lv 54 — so no single class can finish it unaided.

7 of the 12 raw materials come out of the ground, and 2 of them are time-gated: Silkworm Cocoon (1:00) 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, Rubber has the widest use: 191 recipes call for it, spanning four of the eight crafting classes.
