Doman Iron File

Taken all the way down to base materials, one Doman Iron File is 2 crafting steps deep and needs 2 intermediates — Oroshigane Ingot ×2 and Tiger Leather ×1 — which resolve to 4 distinct raw materials totalling 14 units, plus 20 crystals.

That bill outweighs 6,557 of the 13,602 recipes tracked here and 699 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

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

The chain crosses two disciplines — Blacksmith to Lv 65 and Leatherworker to Lv 64 — so no single class can finish it unaided.

3 of the 4 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.
