Boarskin Pot Helm

Taken all the way down to base materials, one Boarskin Pot Helm is 3 crafting steps deep and needs 6 intermediates — Aldgoat Leather ×1, Aquamarine ×1, Boar Leather ×1 and 3 others — which resolve to 7 distinct raw materials totalling 11 units, plus 26 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 724 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 8 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 9 Earth Shard, 9 Fire Shard and 8 Wind Shard.

The chain crosses three disciplines — Leatherworker to Lv 37, Blacksmith to Lv 39 and Goldsmith to Lv 32 — so no single class can finish it unaided.

One intermediate outranks the result: Mythril Rivets is a Lv 39 Blacksmith recipe feeding a Lv 37 craft, so that step, not the last one, is the real gate.

5 of the 7 raw materials match a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.
