Doman Iron Sledgehammer

Taken all the way down to base materials, one Doman Iron Sledgehammer is 2 crafting steps deep and needs 3 intermediates — Oroshigane Ingot ×2, Beetle Glue ×1 and Pine Lumber ×1 — which resolve to 6 distinct raw materials totalling 18 units, plus 24 crystals.

That bill outweighs 7,380 of the 13,602 recipes tracked here and 781 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 8 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 12 Fire Crystal, 4 Earth Crystal, 4 Water Crystal and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 65, Alchemist to Lv 64 and Carpenter to Lv 64 — so no single class can finish it unaided.

4 of the 6 raw materials match a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.

Of the intermediates, Oroshigane Ingot has the widest use: 114 recipes call for it, spanning six of the eight crafting classes.
