Doman Steel Round Knife

Taken all the way down to base materials, one Doman Steel Round Knife is 3 crafting steps deep and needs 6 intermediates — Tama-hagane Ingot ×2, Marid Leather ×1, Persimmon Lumber ×1 and 3 others — which resolve to 8 distinct raw materials totalling 34 units, plus 45 crystals.

That bill outweighs 11,052 of the 13,602 recipes tracked here and 1,301 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 36 are burned by the intermediates, so the real crystal cost is 23 Fire Crystal, 9 Earth Crystal, 8 Wind Crystal and 1 other kind.

The chain crosses five disciplines — Blacksmith to Lv 66, Alchemist to Lv 66, Carpenter to Lv 66, Leatherworker to Lv 66 and Goldsmith to Lv 61 — so no single class can finish it unaided.

7 of the 8 raw materials match a gathering node, none of them timed; the other 1 comes 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.
