Horn Scale Mail

Taken all the way down to base materials, one Horn Scale Mail is 2 crafting steps deep and needs 2 intermediates — Boar Leather ×2 and Steel Ingot ×1 — which resolve to 5 distinct raw materials totalling 8 units, plus 19 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 9 of those crystals go into the final step; the other 10 are burned by the intermediates, so the real crystal cost is 12 Earth Shard, 5 Ice Shard and 2 Fire Shard.

The chain crosses three disciplines — Armorer to Lv 40, Leatherworker to Lv 33 and Blacksmith to Lv 26 — so no single class can finish it unaided.

3 of the 5 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, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
