Rarefied High Steel Claw Hammer

Taken all the way down to base materials, one Rarefied High Steel Claw Hammer is 3 crafting steps deep and needs 3 intermediates — High Steel Ingot ×2, Larch Lumber ×2 and High Steel Nugget ×2 — which resolve to 4 distinct raw materials totalling 26 units, plus 25 crystals.

That bill outweighs 9,543 of the 13,602 recipes tracked here and 1,087 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 16 Fire Crystal, 6 Wind Crystal and 3 Earth Crystal.

The chain crosses two disciplines — Blacksmith to Lv 64 and Carpenter to Lv 62 — so no single class can finish it unaided.

All 4 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, High Steel Nugget has the widest use: 133 recipes call for it, spanning seven of the eight crafting classes.
