Iron Guisarme

Taken all the way down to base materials, one Iron Guisarme is 2 crafting steps deep and needs 3 intermediates — Animal Glue ×1, Elm Lumber ×1 and Iron Ingot ×1 — which resolve to 4 distinct raw materials totalling 9 units, plus 6 crystals.

That bill outweighs 5,492 of the 13,602 recipes tracked here and 549 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 3 are burned by the intermediates, so the real crystal cost is 3 Wind Shard, 1 Fire Shard, 1 Ice Shard and 1 other kind.

The chain crosses three disciplines — Carpenter to Lv 22, Blacksmith to Lv 16 and Alchemist to Lv 2 — 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, Iron Ingot has the widest use: 113 recipes call for it, spanning seven of the eight crafting classes.
