Cauldronmaster's Spectacles ★★

Taken all the way down to base materials, one Cauldronmaster's Spectacles is 3 crafting steps deep and needs 6 intermediates — Aurum Regis Ingot ×3, Crystal Glass ×2, Hardsilver Ingot ×1 and 3 others — which resolve to 14 distinct raw materials totalling 41 units, plus 36 crystals.

That bill outweighs 11,923 of the 13,602 recipes tracked here and 1,918 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 14 Wind Crystal, 10 Water Crystal, 4 Fire Cluster and 2 other kinds.

The chain crosses two disciplines — Goldsmith to Lv 60 and Alchemist to Lv 50 — so no single class can finish it unaided.

10 of the 14 raw materials come out of the ground, and 3 of them are time-gated: Aurum Regis Ore (2:00, 14:00), Violet Quartz (0:00, 12:00) and 1 other. The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Aurum Regis Nugget has the widest use: 185 recipes call for it, spanning seven of the eight crafting classes.
