Doman Steel Tachi

Taken all the way down to base materials, one Doman Steel Tachi is 3 crafting steps deep and needs 6 intermediates — Tama-hagane Ingot ×3, Durium Nugget ×1, Persimmon Lumber ×1 and 3 others — which resolve to 9 distinct raw materials totalling 43 units, plus 52 crystals.

That bill outweighs 12,178 of the 13,602 recipes tracked here and 1,542 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 43 are burned by the intermediates, so the real crystal cost is 32 Fire Crystal, 12 Wind Crystal and 8 Earth Crystal.

The chain crosses four disciplines — Blacksmith to Lv 67, Carpenter to Lv 66, Goldsmith to Lv 64 and Leatherworker to Lv 64 — so no single class can finish it unaided.

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