Inferno Musketoon ★★★

Taken all the way down to base materials, one Inferno Musketoon is 2 crafting steps deep and needs 2 intermediates — Wolfram Ingot ×3 and Black Firesand ×1 — which resolve to 10 distinct raw materials totalling 32 units, plus 24 crystals.

That bill outweighs 10,750 of the 13,602 recipes tracked here and 1,223 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 12 are burned by the intermediates, so the real crystal cost is 12 Fire Crystal, 6 Fire Cluster, 3 Earth Cluster and 1 other kind.

The chain crosses two disciplines — Blacksmith to Lv 50 and Alchemist to Lv 32 — so no single class can finish it unaided.

6 of the 10 raw materials come out of the ground, and one of them is time-gated: Ferberite (3:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Wolfram Ingot has the widest use: 107 recipes call for it, spanning five of the eight crafting classes.
