Doman Iron Longsword

Taken all the way down to base materials, one Doman Iron Longsword is 2 crafting steps deep and needs 4 intermediates — Oroshigane Ingot ×2, Beetle Glue ×1, Durium Nugget ×1 and 1 other — which resolve to 9 distinct raw materials totalling 23 units, plus 26 crystals.

That bill outweighs 8,647 of the 13,602 recipes tracked here and 956 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 19 are burned by the intermediates, so the real crystal cost is 12 Fire Crystal, 6 Earth Crystal, 4 Water Crystal and 1 other kind.

The chain crosses four disciplines — Blacksmith to Lv 64, Alchemist to Lv 64, Goldsmith to Lv 64 and Leatherworker to Lv 61 — so no single class can finish it unaided.

6 of the 9 raw materials match a gathering node, none of them timed; the other 3 come from vendors, drops or content this site does not track.

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