Mythril Zweihander

Taken all the way down to base materials, one Mythril Zweihander is 2 crafting steps deep and needs 3 intermediates — Mythril Ingot ×3, Mahogany Lumber ×1 and Peiste Leather ×1 — which resolve to 4 distinct raw materials totalling 14 units, plus 30 crystals.

That bill outweighs 6,557 of the 13,602 recipes tracked here and 699 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 21 are burned by the intermediates, so the real crystal cost is 17 Fire Shard, 8 Earth Shard and 5 Wind Shard.

The chain crosses three disciplines — Blacksmith to Lv 41, Carpenter to Lv 39 and Leatherworker to Lv 38 — so no single class can finish it unaided.

3 of the 4 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, Mythril Ingot has the widest use: 135 recipes call for it, spanning seven of the eight crafting classes.
