High Steel Doming Hammer

Taken all the way down to base materials, one High Steel Doming Hammer is 2 crafting steps deep and needs 2 intermediates — High Steel Nugget ×3 and Beech Lumber ×1 — which resolve to 3 distinct raw materials totalling 19 units, plus 17 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 804 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 5 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, 3 Wind Crystal and 2 Earth Crystal.

The chain crosses two disciplines — Blacksmith to Lv 61 and Carpenter to Lv 61 — so no single class can finish it unaided.

All 3 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, High Steel Nugget has the widest use: 133 recipes call for it, spanning seven of the eight crafting classes.
