Cobalt Halberd

Taken all the way down to base materials, one Cobalt Halberd is 2 crafting steps deep and needs 4 intermediates — Boar Leather ×1, Cobalt Ingot ×1, Oak Lumber ×1 and 1 other — which resolve to 6 distinct raw materials totalling 11 units, plus 24 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 581 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 14 are burned by the intermediates, so the real crystal cost is 10 Wind Shard, 5 Fire Shard, 5 Ice Shard and 1 other kind.

The chain crosses four disciplines — Carpenter to Lv 44, Blacksmith to Lv 42, Leatherworker to Lv 33 and Goldsmith to Lv 23 — 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, Silver Ingot has the widest use: 157 recipes call for it, spanning eight of the eight crafting classes.
