Gold Thumb's Raising Hammer ★★★

Taken all the way down to base materials, one Gold Thumb's Raising Hammer is 2 crafting steps deep and needs 3 intermediates — Craftsman's Tri-solution ×3, Octahedrite Nugget ×3 and Cronopio Leather ×2 — which resolve to 8 distinct raw materials totalling 51 units, plus 54 crystals.

That bill outweighs 12,830 of the 13,602 recipes tracked here and 1,731 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 48 are burned by the intermediates, so the real crystal cost is 18 Earth Cluster, 12 Fire Cluster, 9 Lightning Cluster and 2 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 100, Alchemist to Lv 100 and Leatherworker to Lv 100 — so no single class can finish it unaided.

3 of the 8 raw materials come out of the ground, and 3 of them are time-gated: Cordia Sap (0:00, 12:00), Octahedrite (10:00, 22:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Octahedrite Nugget has the widest use: 67 recipes call for it, spanning seven of the eight crafting classes.
