Rainbow Bustle

Taken all the way down to base materials, one Rainbow Bustle is 3 crafting steps deep and needs 4 intermediates — Rainbow Cloth ×2, Silver Ingot ×1, Rainbow Thread ×5 and 1 other — which resolve to 5 distinct raw materials totalling 21 units, plus 15 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 10 are burned by the intermediates, so the real crystal cost is 10 Lightning Crystal, 2 Wind Crystal, 2 Wind Shard and 1 other kind.

The chain crosses two disciplines — Weaver to Lv 51 and Goldsmith to Lv 23 — 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, Silver Ingot has the widest use: 157 recipes call for it, spanning eight of the eight crafting classes.
