Cobalt-barreled Carbine

Taken all the way down to base materials, one Cobalt-barreled Carbine is 2 crafting steps deep and needs 5 intermediates — Black Firesand ×1, Cobalt Ingot ×1, Electrum Ingot ×1 and 2 others — which resolve to 10 distinct raw materials totalling 20 units, plus 34 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 851 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 11 Fire Shard, 10 Earth Shard, 10 Wind Shard and 1 other kind.

The chain crosses five disciplines — Blacksmith to Lv 45, Goldsmith to Lv 42, Leatherworker to Lv 41, Carpenter to Lv 39 and Alchemist to Lv 32 — so no single class can finish it unaided.

9 of the 10 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.
