Woolen Cavalier's Hat

Taken all the way down to base materials, one Woolen Cavalier's Hat is 3 crafting steps deep and needs 3 intermediates — Brass Ingot ×1, Undyed Woolen Cloth ×1 and Woolen Yarn ×3 — which resolve to 4 distinct raw materials totalling 8 units, plus 18 crystals.

That bill outweighs 5,254 of the 13,602 recipes tracked here and 610 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 8 are burned by the intermediates, so the real crystal cost is 12 Lightning Shard and 6 Wind Shard.

The chain crosses two disciplines — Weaver to Lv 42 and Goldsmith to Lv 14 — 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, Undyed Woolen Cloth has the widest use: 154 recipes call for it, spanning seven of the eight crafting classes.
