Altered Mythril Chain Coif

Taken all the way down to base materials, one Altered Mythril Chain Coif is 3 crafting steps deep and needs 4 intermediates — Cobalt Ingot ×2, Mythril Rivets ×1, Peiste Leather ×1 and 1 other — which resolve to 5 distinct raw materials totalling 11 units, plus 33 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 555 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 19 Fire Shard, 9 Earth Shard and 5 Ice Shard.

The chain crosses three disciplines — Armorer to Lv 44, Blacksmith to Lv 42 and Leatherworker to Lv 38 — so no single class can finish it unaided.

4 of the 5 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.
