Cobalt Haubergeon

Taken all the way down to base materials, one Cobalt Haubergeon is 3 crafting steps deep and needs 7 intermediates — Cobalt Rings ×3, Boar Leather ×1, Mythril Plate ×1 and 4 others — which resolve to 9 distinct raw materials totalling 22 units, plus 65 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 808 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 53 are burned by the intermediates, so the real crystal cost is 25 Ice Shard, 23 Fire Shard, 10 Earth Shard and 2 other kinds.

The chain crosses five disciplines — Armorer to Lv 50, Weaver to Lv 43, Blacksmith to Lv 42, Leatherworker to Lv 33 and Alchemist to Lv 25 — so no single class can finish it unaided.

6 of the 9 raw materials match a gathering node, none of them timed; the other 3 come 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.
