Hard Leather Pot Helm

Taken all the way down to base materials, one Hard Leather Pot Helm is 3 crafting steps deep and needs 4 intermediates — Bronze Rivets ×1, Hard Leather ×1, Leather ×1 and 1 other — which resolve to 4 distinct raw materials totalling 5 units, plus 6 crystals.

That bill outweighs 4,201 of the 13,602 recipes tracked here and 489 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 Earth Shard, 2 Fire Shard and 1 Wind Shard.

The chain crosses two disciplines — Leatherworker to Lv 8 and Blacksmith to Lv 3 — so no single class can finish it unaided.

2 of the 4 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, Bronze Ingot has the widest use: 76 recipes call for it, spanning six of the eight crafting classes.
