Portaled Partition

Taken all the way down to base materials, one Portaled Partition is 2 crafting steps deep and needs 2 intermediates — Integral Lumber ×8 and Palm Lumber ×6 — which resolve to 2 distinct raw materials totalling 70 units, plus 176 crystals.

That bill outweighs 13,294 of the 13,602 recipes tracked here and 1,460 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 64 of those crystals go into the final step; the other 112 are burned by the intermediates, so the real crystal cost is 144 Wind Crystal and 32 Ice Crystal.

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

Both raw materials are gathered, and no spot for either is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Integral Lumber has the widest use: 114 recipes call for it, spanning seven of the eight crafting classes.
