Glamour Prism

Taken all the way down to base materials, one Glamour Prism is 2 crafting steps deep and needs 1 intermediate — Toad Leather ×2 — which resolves to 3 distinct raw materials totalling 5 units, plus 6 crystals.

That bill outweighs 4,201 of the 13,602 recipes tracked here and 489 of the 1,844 Leatherworker 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 Earth Shard, 1 Earth Crystal and 1 Wind Crystal.

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

One intermediate outranks the result: Toad Leather is a Lv 26 Leatherworker recipe feeding a Lv 15 craft, so that step, not the last one, is the real gate.

1 of the 3 raw materials matches a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.
