Rainbow Cap of Casting

Taken all the way down to base materials, one Rainbow Cap of Casting is 3 crafting steps deep and needs 3 intermediates — Rainbow Cloth ×3, Rainbow Thread ×7 and Dew Thread ×3 — which resolve to 3 distinct raw materials totalling 24 units, plus 17 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 1,178 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 12 are burned by the intermediates, so the real crystal cost is 13 Lightning Crystal, 2 Lightning Shard and 2 Wind Crystal.

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.

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