Faust Striking Dummy ★★★

Taken all the way down to base materials, one Faust Striking Dummy is 2 crafting steps deep and needs 1 intermediate — High Mythrite Ingot ×2 — which resolves to 7 distinct raw materials totalling 21 units, plus 15 crystals.

That bill outweighs 8,152 of the 13,602 recipes tracked here and 780 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 10 are burned by the intermediates, so the real crystal cost is 6 Earth Cluster, 6 Fire Cluster and 3 Ice Cluster.

The chain crosses two disciplines — Armorer to Lv 60 and Blacksmith to Lv 60 — so no single class can finish it unaided.

2 of the 7 raw materials come out of the ground, and one of them is time-gated: Lumythrite Ore (2:00, 14:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, High Mythrite Ingot has the widest use: 150 recipes call for it, spanning seven of the eight crafting classes.
