Crested Necklace of Crafting ★★★

Taken all the way down to base materials, one Crested Necklace of Crafting is 2 crafting steps deep and needs 3 intermediates — Cordia Lumber ×2, Desert Lapis ×2 and Octahedrite Nugget ×2 — which resolve to 8 distinct raw materials totalling 38 units, plus 42 crystals.

That bill outweighs 11,698 of the 13,602 recipes tracked here and 1,875 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 36 are burned by the intermediates, so the real crystal cost is 15 Fire Cluster, 15 Wind Cluster, 6 Earth Cluster and 1 other kind.

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

3 of the 8 raw materials come out of the ground, and 3 of them are time-gated: Cordia Log (0:00, 12:00), Desert Lapis Ore (2:00, 14:00) and 1 other. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Octahedrite Nugget has the widest use: 67 recipes call for it, spanning seven of the eight crafting classes.
