Cobalt Knuckles

Taken all the way down to base materials, one Cobalt Knuckles is 2 crafting steps deep and needs 2 intermediates — Cobalt Ingot ×2 and Boar Leather ×1 — which resolve to 4 distinct raw materials totalling 8 units, plus 24 crystals.

That bill outweighs 5,254 of the 13,602 recipes tracked here and 529 of the 1,932 Blacksmith 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 15 Fire Shard and 9 Earth Shard.

The chain crosses two disciplines — Blacksmith to Lv 42 and Leatherworker to Lv 33 — 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, Cobalt Ingot has the widest use: 145 recipes call for it, spanning seven of the eight crafting classes.
