Rainbow Cloth

Taken all the way down to base materials, one Rainbow Cloth is 2 crafting steps deep and needs 2 intermediates — Rainbow Thread ×2 and Dew Thread ×1 — which resolve to 3 distinct raw materials totalling 7 units, plus 4 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 557 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 2 are burned by the intermediates, so the real crystal cost is 3 Lightning Crystal and 1 Lightning Shard.

Every step is Weaver work, from a Lv 23 intermediate up to the Lv 51 finish, so one class covers the whole chain.

2 of the 3 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Rainbow Cloth is itself consumed by 48 further recipes, spanning six of the eight crafting classes.
