Rakshasa Zori of Casting ★★★★

Taken all the way down to base materials, one Rakshasa Zori of Casting is 3 crafting steps deep and needs 5 intermediates — Procoptodon Leather ×2, Grade 4 Reisui of Intelligence ×1, Ruby Cotton Cloth ×1 and 2 others — which resolve to 9 distinct raw materials totalling 21 units, plus 19 crystals.

That bill outweighs 8,152 of the 13,602 recipes tracked here and 1,103 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 15 are burned by the intermediates, so the real crystal cost is 6 Wind Cluster, 4 Earth Cluster, 3 Lightning Crystal and 3 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 70, Alchemist to Lv 70, Carpenter to Lv 70 and Weaver to Lv 62 — so no single class can finish it unaided.

4 of the 9 raw materials come out of the ground, and 2 of them are time-gated: Azim Spring Water (8:00, 20:00) and Urunday Log (4:00, 16:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Ruby Cotton Yarn has the widest use: 91 recipes call for it, spanning six of the eight crafting classes.
