Glamour Prism

Taken all the way down to base materials, one Glamour Prism is 2 crafting steps deep and needs 1 intermediate — Silver Ingot ×2 — which resolves to 2 distinct raw materials totalling 7 units, plus 6 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 710 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 4 are burned by the intermediates, so the real crystal cost is 4 Wind Shard, 1 Fire Crystal and 1 Wind Crystal.

Every step is Goldsmith work, so one class covers the whole chain.

One intermediate outranks the result: Silver Ingot is a Lv 23 Goldsmith recipe feeding a Lv 15 craft, so that step, not the last one, is the real gate.

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