Platinum Ring of Aiming ★★★★

Taken all the way down to base materials, one Platinum Ring of Aiming is 2 crafting steps deep and needs 3 intermediates — Platinum Ingot ×3, Gold Ingot ×1 and Iolite ×1 — which resolve to 9 distinct raw materials totalling 41 units, plus 22 crystals.

That bill outweighs 11,923 of the 13,602 recipes tracked here and 1,918 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 12 Wind Cluster and 10 Fire Cluster.

Every step is Goldsmith work, from a Lv 50 intermediate up to the Lv 50 finish, so one class covers the whole chain.

4 of the 9 raw materials come out of the ground, and 4 of them are time-gated: Gold Ore (9:00), Native Gold (4:00) and 2 others. The widest gap between consecutive opening times is 18 Eorzean hours, about 53 real-world minutes.

Of the intermediates, Gold Ingot has the widest use: 184 recipes call for it, spanning seven of the eight crafting classes.
