Island Prism ★★

Taken all the way down to base materials, a batch of 3 Island Prism is 2 crafting steps deep and needs 1 intermediate — Palm Lumber ×3 — which resolves to 2 distinct raw materials totalling 17 units, plus 30 crystals.

That bill outweighs 7,161 of the 13,602 recipes tracked here and 692 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 24 Wind Crystal, 3 Ice Cluster and 3 Wind Cluster.

Every step is Carpenter work, from a Lv 82 intermediate up to the Lv 90 finish, so one class covers the whole chain.

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.

Of the intermediates, Palm Lumber has the widest use: 38 recipes call for it, spanning seven of the eight crafting classes.
