Aurum Regis Ingot ★★

Taken all the way down to base materials, a batch of 3 Aurum Regis Ingot is 2 crafting steps deep and needs 1 intermediate — Aurum Regis Nugget ×1 — which resolves to 5 distinct raw materials totalling 14 units, plus 9 crystals.

That bill outweighs 6,557 of the 13,602 recipes tracked here and 907 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 5 are burned by the intermediates, so the real crystal cost is 5 Wind Crystal, 2 Fire Cluster and 2 Wind Cluster.

Every step is Goldsmith work, from a Lv 58 intermediate up to the Lv 60 finish, so one class covers the whole chain.

4 of the 5 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.

Aurum Regis Ingot is itself consumed by 25 further recipes, spanning six of the eight crafting classes.
