Doman Steel Longsword

Taken all the way down to base materials, one Doman Steel Longsword is 3 crafting steps deep and needs 5 intermediates — Tama-hagane Ingot ×2, Beetle Glue ×1, Durium Ingot ×1 and 2 others — which resolve to 9 distinct raw materials totalling 36 units, plus 44 crystals.

That bill outweighs 11,383 of the 13,602 recipes tracked here and 1,369 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 35 are burned by the intermediates, so the real crystal cost is 27 Fire Crystal, 9 Wind Crystal, 4 Earth Crystal and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 66, Goldsmith to Lv 66 and Alchemist to Lv 64 — so no single class can finish it unaided.

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