Durium Lapidary Hammer

Taken all the way down to base materials, one Durium Lapidary Hammer is 3 crafting steps deep and needs 7 intermediates — Durium Ingot ×2, Opal ×1, Persimmon Lumber ×1 and 4 others — which resolve to 9 distinct raw materials totalling 37 units, plus 51 crystals.

That bill outweighs 11,564 of the 13,602 recipes tracked here and 1,403 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 42 are burned by the intermediates, so the real crystal cost is 33 Wind Crystal, 14 Fire Crystal and 4 Earth Crystal.

The chain crosses three disciplines — Blacksmith to Lv 66, Carpenter to Lv 66 and Goldsmith to Lv 66 — so no single class can finish it unaided.

All 9 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, Durium Nugget has the widest use: 142 recipes call for it, spanning seven of the eight crafting classes.
