Doman Iron Glaives

Taken all the way down to base materials, one Doman Iron Glaives is 2 crafting steps deep and needs 4 intermediates — Oroshigane Ingot ×2, Durium Nugget ×1, Koppranickel Nugget ×1 and 1 other — which resolve to 7 distinct raw materials totalling 23 units, plus 25 crystals.

That bill outweighs 8,647 of the 13,602 recipes tracked here and 956 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 12 Fire Crystal, 10 Wind Crystal and 3 Earth Crystal.

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

All 7 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, Durium Nugget has the widest use: 142 recipes call for it, spanning seven of the eight crafting classes.
