Titanium Gold Maul

Taken all the way down to base materials, one Titanium Gold Maul is 2 crafting steps deep and needs 2 intermediates — Acacia Lumber ×2 and Titanium Gold Nugget ×2 — which resolve to 3 distinct raw materials totalling 22 units, plus 48 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 917 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 24 Fire Crystal, 16 Wind Crystal and 8 Earth Crystal.

The chain crosses two disciplines — Blacksmith to Lv 97 and Carpenter to Lv 96 — so no single class can finish it unaided.

All 3 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Titanium Gold Nugget has the widest use: 110 recipes call for it, spanning seven of the eight crafting classes.
