Glamour Prism

Taken all the way down to base materials, one Glamour Prism is 3 crafting steps deep and needs 2 intermediates — Growth Formula Gamma ×2 and Quicksilver ×2 — which resolve to 4 distinct raw materials totalling 9 units, plus 10 crystals.

That bill outweighs 5,492 of the 13,602 recipes tracked here and 1,090 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 8 are burned by the intermediates, so the real crystal cost is 8 Water Shard, 1 Lightning Crystal and 1 Water Crystal.

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

One intermediate outranks the result: Growth Formula Gamma is a Lv 30 Alchemist recipe feeding a Lv 15 craft, so that step, not the last one, is the real gate.

2 of the 4 raw materials match a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.
