High Steel Headsman's Axe

Taken all the way down to base materials, one High Steel Headsman's Axe is 2 crafting steps deep and needs 5 intermediates — High Steel Nugget ×3, Beech Lumber ×1, Koppranickel Nugget ×1 and 2 others — which resolve to 9 distinct raw materials totalling 38 units, plus 28 crystals.

That bill outweighs 11,698 of the 13,602 recipes tracked here and 1,430 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 16 Fire Crystal, 6 Wind Crystal, 4 Water Crystal and 1 other kind.

The chain crosses four disciplines — Blacksmith to Lv 61, Carpenter to Lv 61, Goldsmith to Lv 61 and Alchemist to Lv 55 — so no single class can finish it unaided.

6 of the 9 raw materials match a gathering node, none of them timed; the other 3 come from vendors, drops or content this site does not track.

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