Goatskin Armguards

Taken all the way down to base materials, one Goatskin Armguards is 3 crafting steps deep and needs 3 intermediates — Aldgoat Leather ×2, Iron Rivets ×1 and Iron Ingot ×1 — which resolve to 3 distinct raw materials totalling 7 units, plus 7 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 598 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 4 are burned by the intermediates, so the real crystal cost is 4 Earth Shard, 2 Fire Shard and 1 Wind Shard.

The chain crosses two disciplines — Leatherworker to Lv 22 and Blacksmith to Lv 18 — so no single class can finish it unaided.

2 of the 3 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, Iron Ingot has the widest use: 113 recipes call for it, spanning seven of the eight crafting classes.
