Ra'Kaznar Cross-pein Hammer

Taken all the way down to base materials, one Ra'Kaznar Cross-pein Hammer is 2 crafting steps deep and needs 3 intermediates — Claro Walnut Lumber ×2, Ra'Kaznar Ingot ×2 and Titanium Gold Nugget ×1 — which resolve to 5 distinct raw materials totalling 28 units, plus 56 crystals.

That bill outweighs 9,936 of the 13,602 recipes tracked here and 1,152 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 32 Fire Crystal, 16 Wind Crystal and 8 Earth Crystal.

The chain crosses two disciplines — Blacksmith to Lv 100 and Carpenter to Lv 98 — so no single class can finish it unaided.

All 5 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, Ra'Kaznar Ingot has the widest use: 166 recipes call for it, spanning seven of the eight crafting classes.
