Titanium Ball-pein Hammer

Taken all the way down to base materials, one Titanium Ball-pein Hammer is 2 crafting steps deep and needs 3 intermediates — Darksteel Nugget ×2, Titanium Nugget ×2 and Dhalmel Leather ×1 — which resolve to 6 distinct raw materials totalling 24 units, plus 26 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 1,021 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

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

The chain crosses two disciplines — Blacksmith to Lv 55 and Leatherworker to Lv 54 — so no single class can finish it unaided.

5 of the 6 raw materials come out of the ground, and one of them is time-gated: Darksteel Ore (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

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