Rainbow Ribbon of Casting

Taken all the way down to base materials, one Rainbow Ribbon of Casting is 3 crafting steps deep and needs 5 intermediates — Rainbow Cloth ×2, Agate ×1, Rainbow Thread ×5 and 2 others — which resolve to 5 distinct raw materials totalling 21 units, plus 21 crystals.

That bill outweighs 8,152 of the 13,602 recipes tracked here and 1,065 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 10 Lightning Crystal, 5 Wind Crystal, 5 Wind Shard and 1 other kind.

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

4 of the 5 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, Rainbow Thread has the widest use: 116 recipes call for it, spanning five of the eight crafting classes.
