Platinum Earrings of Slaying ★★★★

Taken all the way down to base materials, one Platinum Earrings of Slaying is 2 crafting steps deep and needs 2 intermediates — Platinum Ingot ×3 and Ruby ×2 — which resolve to 6 distinct raw materials totalling 40 units, plus 22 crystals.

That bill outweighs 11,825 of the 13,602 recipes tracked here and 1,904 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.

2 of the 6 raw materials come out of the ground, and 2 of them are time-gated: Platinum Ore (4:00) and Raw Ruby (18:00). The widest gap between consecutive opening times is 14 Eorzean hours, about 41 real-world minutes.

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