Rakshasa Ring of Casting ★★★★

Taken all the way down to base materials, one Rakshasa Ring of Casting is 3 crafting steps deep and needs 4 intermediates — Evergleam Ingot ×2, Grade 4 Reisui of Intelligence ×1, Oroshigane Ingot ×1 and 1 other — which resolve to 10 distinct raw materials totalling 21 units, plus 21 crystals.

That bill outweighs 8,152 of the 13,602 recipes tracked here and 1,199 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 17 are burned by the intermediates, so the real crystal cost is 5 Wind Crystal, 4 Fire Cluster, 4 Fire Crystal and 3 other kinds.

The chain crosses three disciplines — Goldsmith to Lv 70, Alchemist to Lv 70 and Blacksmith to Lv 64 — so no single class can finish it unaided.

7 of the 10 raw materials come out of the ground, and 2 of them are time-gated: Azim Spring Water (8:00, 20:00) and Evergleam Ore (10:00, 22:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

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