Iron Scale Mail

Taken all the way down to base materials, one Iron Scale Mail is 3 crafting steps deep and needs 4 intermediates — Aldgoat Leather ×2, Iron Plate ×1, Silver Ingot ×1 and 1 other — which resolve to 4 distinct raw materials totalling 13 units, plus 10 crystals.

That bill outweighs 6,426 of the 13,602 recipes tracked here and 599 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 7 are burned by the intermediates, so the real crystal cost is 3 Earth Shard, 3 Ice Shard, 2 Fire Shard and 1 other kind.

The chain crosses four disciplines — Armorer to Lv 23, Goldsmith to Lv 23, Leatherworker to Lv 17 and Blacksmith to Lv 16 — 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, Silver Ingot has the widest use: 157 recipes call for it, spanning eight of the eight crafting classes.
