Iron Lance

Taken all the way down to base materials, one Iron Lance is 2 crafting steps deep and needs 3 intermediates — Iron Ingot ×2, Elm Lumber ×1 and Hard Leather ×1 — which resolve to 3 distinct raw materials totaling 10 units, plus 6 crystals.

That bill outweighs 5,754 of the 13,602 recipes tracked here and 568 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 4 are burned by the intermediates, so the real crystal cost is 2 Fire Shard, 2 Wind Shard, 1 Earth Shard and 1 other kind.

The chain crosses three disciplines — Carpenter to Lv 20, Blacksmith to Lv 16 and Leatherworker to Lv 8 — so no single class can finish it unaided.

2 of the 3 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, Iron Ingot has the widest use: 113 recipes call for it, spanning seven of the eight crafting classes.
