Doman Iron Greaves of Maiming

Taken all the way down to base materials, one Doman Iron Greaves of Maiming is 3 crafting steps deep and needs 6 intermediates — Oroshigane Ingot ×2, Grade 1 Reisui of Strength ×1, Koppranickel Ingot ×1 and 3 others — which resolve to 12 distinct raw materials totalling 30 units, plus 30 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,081 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 8 Fire Crystal, 7 Earth Crystal, 6 Wind Crystal and 3 other kinds.

The chain crosses five disciplines — Armorer to Lv 64, Blacksmith to Lv 64, Leatherworker to Lv 64, Alchemist to Lv 63 and Goldsmith to Lv 62 — so no single class can finish it unaided.

11 of the 12 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, Rubber has the widest use: 191 recipes call for it, spanning four of the eight crafting classes.
