Rainbow Breeches

Taken all the way down to base materials, one Rainbow Breeches is 3 crafting steps deep and needs 4 intermediates — Electrum Ingot ×1, Rainbow Cloth ×1, Rainbow Thread ×3 and 1 other — which resolve to 5 distinct raw materials totalling 17 units, plus 15 crystals.

That bill outweighs 7,161 of the 13,602 recipes tracked here and 916 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 10 are burned by the intermediates, so the real crystal cost is 7 Lightning Crystal, 5 Wind Shard, 2 Wind Crystal and 1 other kind.

The chain crosses two disciplines — Weaver to Lv 51 and Goldsmith to Lv 42 — so no single class can finish it unaided.

3 of the 5 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, Electrum Ingot has the widest use: 234 recipes call for it, spanning seven of the eight crafting classes.
