Boarskin Jerkin

Taken all the way down to base materials, one Boarskin Jerkin is 3 crafting steps deep and needs 4 intermediates — Boar Leather ×3, Silver Ingot ×1, Undyed Woolen Cloth ×1 and 1 other — which resolve to 4 distinct raw materials totalling 11 units, plus 29 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 10 of those crystals go into the final step; the other 19 are burned by the intermediates, so the real crystal cost is 17 Earth Shard, 7 Wind Shard and 5 Lightning Shard.

The chain crosses three disciplines — Leatherworker to Lv 43, Weaver to Lv 39 and Goldsmith to Lv 23 — 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, Silver Ingot has the widest use: 157 recipes call for it, spanning eight of the eight crafting classes.
