Doman Iron Uchigatana

Taken all the way down to base materials, one Doman Iron Uchigatana is 3 crafting steps deep and needs 7 intermediates — Oroshigane Ingot ×3, Koppranickel Nugget ×1, Kudzu Cloth ×1 and 4 others — which resolve to 8 distinct raw materials totalling 35 units, plus 34 crystals.

That bill outweighs 11,223 of the 13,602 recipes tracked here and 1,335 of the 1,932 Blacksmith ones, and 337 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, 9 Wind Crystal, 5 Lightning Crystal and 1 other kind.

The chain crosses four disciplines — Blacksmith to Lv 65, Weaver to Lv 64, Carpenter to Lv 62 and Goldsmith to Lv 61 — so no single class can finish it unaided.

All 8 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Koppranickel Nugget has the widest use: 124 recipes call for it, spanning seven of the eight crafting classes.
