Platinum Circlet of Casting ★★★★

Taken all the way down to base materials, one Platinum Circlet of Casting is 2 crafting steps deep and needs 4 intermediates — Platinum Ingot ×3, Platinum Nugget ×1, Silk Thread ×1 and 1 other — which resolve to 7 distinct raw materials totalling 42 units, plus 25 crystals.

That bill outweighs 12,044 of the 13,602 recipes tracked here and 1,940 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 21 are burned by the intermediates, so the real crystal cost is 11 Fire Cluster, 10 Wind Cluster, 3 Lightning Crystal and 1 other kind.

The chain crosses three disciplines — Goldsmith to Lv 50, Blacksmith to Lv 50 and Weaver to Lv 50 — so no single class can finish it unaided.

5 of the 7 raw materials come out of the ground, and 3 of them are time-gated: Ferberite (3:00), Platinum Ore (4:00) and 1 other. The widest gap between consecutive opening times is 21 Eorzean hours, about 61 real-world minutes.

Of the intermediates, Platinum Ingot has the widest use: 176 recipes call for it, spanning seven of the eight crafting classes.
