Rakshasa Tsutsu-hakama of Casting ★★★★

Taken all the way down to base materials, one Rakshasa Tsutsu-hakama of Casting is 3 crafting steps deep and needs 5 intermediates — Stardust Cotton Cloth ×3, Grade 4 Reisui of Intelligence ×2, Evergleam Ingot ×1 and 2 others — which resolve to 12 distinct raw materials totalling 33 units, plus 27 crystals.

That bill outweighs 10,907 of the 13,602 recipes tracked here and 1,541 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 8 Lightning Cluster, 8 Wind Cluster, 5 Wind Crystal and 3 other kinds.

The chain crosses three disciplines — Weaver to Lv 70, Alchemist to Lv 70 and Goldsmith to Lv 70 — so no single class can finish it unaided.

8 of the 12 raw materials come out of the ground, and 3 of them are time-gated: Azim Spring Water (8:00, 20:00), Evergleam Ore (10:00, 22:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Palladium Nugget has the widest use: 129 recipes call for it, spanning seven of the eight crafting classes.
