Doman Iron Greatsword

Taken all the way down to base materials, one Doman Iron Greatsword is 2 crafting steps deep and needs 5 intermediates — Oroshigane Ingot ×3, Beetle Glue ×1, Durium Nugget ×1 and 2 others — which resolve to 10 distinct raw materials totalling 32 units, plus 34 crystals.

That bill outweighs 10,750 of the 13,602 recipes tracked here and 1,223 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 8 of those crystals go into the final step; the other 26 are burned by the intermediates, so the real crystal cost is 16 Fire Crystal, 7 Earth Crystal, 7 Wind Crystal and 1 other kind.

The chain crosses five disciplines — Blacksmith to Lv 65, Alchemist to Lv 64, Goldsmith to Lv 64, Carpenter to Lv 62 and Leatherworker to Lv 62 — so no single class can finish it unaided.

7 of the 10 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.
