Ceremonial Necklace of Casting ★★★

Taken all the way down to base materials, one Ceremonial Necklace of Casting is 3 crafting steps deep and needs 5 intermediates — Black Star ×1, Cordia Lumber ×1, Grade 3 Gemsap of Intelligence ×1 and 2 others — which resolve to 11 distinct raw materials totalling 25 units, plus 40 crystals.

That bill outweighs 9,313 of the 13,602 recipes tracked here and 1,507 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 34 are burned by the intermediates, so the real crystal cost is 9 Wind Cluster, 8 Water Crystal, 8 Wind Crystal and 4 other kinds.

The chain crosses three disciplines — Goldsmith to Lv 100, Alchemist to Lv 100 and Carpenter to Lv 100 — so no single class can finish it unaided.

7 of the 11 raw materials come out of the ground, and 3 of them are time-gated: Cordia Log (0:00, 12:00), Fulgurite (2:00, 14:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Black Star has the widest use: 161 recipes call for it, spanning six of the eight crafting classes.
