Rarefied Doman Iron Greaves

Taken all the way down to base materials, one Rarefied Doman Iron Greaves is 3 crafting steps deep and needs 4 intermediates — Oroshigane Ingot ×2, Koppranickel Ingot ×1, Tiger Leather ×1 and 1 other — which resolve to 7 distinct raw materials totalling 23 units, plus 27 crystals.

That bill outweighs 8,647 of the 13,602 recipes tracked here and 847 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 8 Earth Crystal, 8 Fire Crystal, 6 Wind Crystal and 1 other kind.

The chain crosses four disciplines — Armorer to Lv 66, Blacksmith to Lv 64, Leatherworker to Lv 64 and Goldsmith to Lv 62 — so no single class can finish it unaided.

6 of the 7 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, Koppranickel Nugget has the widest use: 124 recipes call for it, spanning seven of the eight crafting classes.
