Cobalt Chain Coif

Taken all the way down to base materials, one Cobalt Chain Coif is 3 crafting steps deep and needs 4 intermediates — Cobalt Rings ×2, Boar Leather ×1, Cobalt Plate ×1 and 1 other — which resolve to 4 distinct raw materials totalling 14 units, plus 51 crystals.

That bill outweighs 6,557 of the 13,602 recipes tracked here and 608 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 39 are burned by the intermediates, so the real crystal cost is 21 Ice Shard, 20 Fire Shard and 10 Earth Shard.

The chain crosses three disciplines — Armorer to Lv 50, 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.
