Amateur's Headgear

Taken all the way down to base materials, one Amateur's Headgear is 3 crafting steps deep and needs 3 intermediates — Bronze Ingot ×2, Bronze Rivets ×1 and Hard Leather ×1 — which resolve to 3 distinct raw materials totaling 7 units, plus 6 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 2 of those crystals go into the final step; the other 4 are burned by the intermediates, so the real crystal cost is 3 Fire Shard, 2 Earth Shard and 1 Wind Shard.

The chain crosses two disciplines — Leatherworker to Lv 11 and Blacksmith to Lv 3 — 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, Bronze Ingot has the widest use: 76 recipes call for it, spanning six of the eight crafting classes.
