Riviera Path Light ★★★

Taken all the way down to base materials, one Riviera Path Light is 2 crafting steps deep and needs 2 intermediates — Darksteel Nugget ×3 and Wolfram Ingot ×3 — which resolve to 6 distinct raw materials totalling 25 units, plus 21 crystals.

That bill outweighs 9,313 of the 13,602 recipes tracked here and 1,056 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 9 Fire Crystal, 8 Fire Cluster and 4 Earth Cluster.

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

3 of the 6 raw materials come out of the ground, and 2 of them are time-gated: Darksteel Ore (1:00) and Ferberite (3:00). The widest gap between consecutive opening times is 22 Eorzean hours, about 64 real-world minutes.

Of the intermediates, Darksteel Nugget has the widest use: 121 recipes call for it, spanning seven of the eight crafting classes.
