Steel Broadsword

Taken all the way down to base materials, one Steel Broadsword is 2 crafting steps deep and needs 2 intermediates — Steel Ingot ×1 and Walnut Lumber ×1 — which resolve to 4 distinct raw materials totalling 7 units, plus 9 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 507 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 4 are burned by the intermediates, so the real crystal cost is 5 Fire Shard, 2 Earth Shard and 2 Wind Shard.

The chain crosses two disciplines — Blacksmith to Lv 28 and Carpenter to Lv 25 — 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, Walnut Lumber has the widest use: 128 recipes call for it, spanning eight of the eight crafting classes.
