Star Spinel Choker of Casting

Taken all the way down to base materials, one Star Spinel Choker of Casting is 2 crafting steps deep and needs 4 intermediates — Koppranickel Nugget ×2, Durium Nugget ×1, Grade 1 Reisui of Intelligence ×1 and 1 other — which resolve to 10 distinct raw materials totalling 25 units, plus 26 crystals.

That bill outweighs 9,313 of the 13,602 recipes tracked here and 1,507 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 8 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 18 Wind Crystal, 4 Fire Crystal and 4 Water Crystal.

The chain crosses two disciplines — Goldsmith to Lv 65 and Alchemist to Lv 63 — so no single class can finish it unaided.

All 10 raw materials are gathered, and one of them is time-gated: Raw Star Spinel (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Durium Nugget has the widest use: 142 recipes call for it, spanning seven of the eight crafting classes.
