Cotton Doublet Vest of Crafting

Taken all the way down to base materials, one Cotton Doublet Vest of Crafting is 3 crafting steps deep and needs 4 intermediates — Brass Ingot ×1, Hard Leather ×1, Undyed Cotton Cloth ×1 and 1 other — which resolve to 4 distinct raw materials totalling 8 units, plus 8 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 3 of those crystals go into the final step; the other 5 are burned by the intermediates, so the real crystal cost is 5 Lightning Shard, 2 Wind Shard and 1 Earth Shard.

The chain crosses three disciplines — Weaver to Lv 23, Goldsmith to Lv 14 and Leatherworker to Lv 8 — 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, Brass Ingot has the widest use: 94 recipes call for it, spanning seven of the eight crafting classes.
