Cobalt Katzbalger

Taken all the way down to base materials, one Cobalt Katzbalger is 2 crafting steps deep and needs 4 intermediates — Cobalt Ingot ×2, Boar Leather ×1, Electrum Ingot ×1 and 1 other — which resolve to 6 distinct raw materials totalling 15 units, plus 32 crystals.

That bill outweighs 6,735 of the 13,602 recipes tracked here and 730 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 22 are burned by the intermediates, so the real crystal cost is 15 Fire Shard, 9 Earth Shard and 8 Wind Shard.

The chain crosses four disciplines — Blacksmith to Lv 42, Goldsmith to Lv 42, Leatherworker to Lv 33 and Carpenter to Lv 32 — so no single class can finish it unaided.

5 of the 6 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, Electrum Ingot has the widest use: 234 recipes call for it, spanning seven of the eight crafting classes.
