Tortoiseshell Scale Mail

Taken all the way down to base materials, one Tortoiseshell Scale Mail is 2 crafting steps deep and needs 3 intermediates — Boar Leather ×1, Cobalt Ingot ×1 and Raptor Leather ×1 — which resolve to 7 distinct raw materials totalling 8 units, plus 25 crystals.

That bill outweighs 5,254 of the 13,602 recipes tracked here and 514 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 14 are burned by the intermediates, so the real crystal cost is 14 Earth Shard, 6 Ice Shard and 5 Fire Shard.

The chain crosses three disciplines — Armorer to Lv 45, Blacksmith to Lv 42 and Leatherworker to Lv 41 — so no single class can finish it unaided.

5 of the 7 raw materials match a gathering node, none of them timed; the other 2 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.
