Rarefied Doman Steel Patas

Taken all the way down to base materials, one Rarefied Doman Steel Patas is 3 crafting steps deep and needs 3 intermediates — Tama-hagane Ingot ×2, Persimmon Lumber ×1 and Oroshigane Ingot ×3 — which resolve to 4 distinct raw materials totalling 27 units, plus 37 crystals.

That bill outweighs 9,763 of the 13,602 recipes tracked here and 1,123 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 27 are burned by the intermediates, so the real crystal cost is 27 Fire Crystal, 5 Earth Crystal and 5 Wind Crystal.

The chain crosses two disciplines — Blacksmith to Lv 68 and Carpenter to Lv 66 — so no single class can finish it unaided.

All 4 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, Oroshigane Ingot has the widest use: 114 recipes call for it, spanning six of the eight crafting classes.
