Sky Pirate's Bottoms of Casting ★★

Taken all the way down to base materials, one Sky Pirate's Bottoms of Casting is 3 crafting steps deep and needs 5 intermediates — Cloud Cloth ×2, Grade 1 Intelligence Dissolvent ×2, Amphiptere Leather ×1 and 2 others — which resolve to 11 distinct raw materials totalling 28 units, plus 25 crystals.

That bill outweighs 9,936 of the 13,602 recipes tracked here and 1,333 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 21 are burned by the intermediates, so the real crystal cost is 6 Lightning Cluster, 5 Earth Crystal, 4 Water Crystal and 3 other kinds.

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

8 of the 11 raw materials come out of the ground, and 2 of them are time-gated: Cloud Cotton Boll (0:00, 4:00, 8:00, 12:00, 16:00, 20:00) and Volcanic Rock Salt (17:00). The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

Of the intermediates, Amphiptere Leather has the widest use: 108 recipes call for it, spanning seven of the eight crafting classes.
