Sky Pirate's Coat of Casting ★★

Taken all the way down to base materials, one Sky Pirate's Coat of Casting is 3 crafting steps deep and needs 7 intermediates — Cloud Cloth ×2, Grade 1 Intelligence Dissolvent ×2, Chimerical Felt ×1 and 4 others — which resolve to 15 distinct raw materials totalling 34 units, plus 30 crystals.

That bill outweighs 11,052 of the 13,602 recipes tracked here and 1,565 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 26 are burned by the intermediates, so the real crystal cost is 7 Lightning Crystal, 6 Lightning Cluster, 5 Wind Cluster and 4 other kinds.

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

10 of the 15 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, Chimerical Felt has the widest use: 113 recipes call for it, spanning six of the eight crafting classes.
