Toadskin Armguards

Taken all the way down to base materials, one Toadskin Armguards is 3 crafting steps deep and needs 3 intermediates — Steel Ingot ×2, Toad Leather ×2 and Steel Rivets ×1 — which resolve to 4 distinct raw materials totalling 10 units, plus 17 crystals.

That bill outweighs 5,754 of the 13,602 recipes tracked here and 691 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 11 are burned by the intermediates, so the real crystal cost is 7 Earth Shard, 7 Fire Shard and 3 Wind Shard.

The chain crosses two disciplines — Leatherworker to Lv 30 and Blacksmith to Lv 29 — 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, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
