Wooden Frame Partition

Taken all the way down to base materials, one Wooden Frame Partition is 2 crafting steps deep and needs 3 intermediates — Acacia Lumber ×5, Claro Walnut Lumber ×5 and Dark Mahogany Lumber ×5 — which resolve to 3 distinct raw materials totalling 75 units, plus 136 crystals.

That bill outweighs 13,370 of the 13,602 recipes tracked here and 1,471 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 120 are burned by the intermediates, so the real crystal cost is 128 Wind Crystal and 8 Ice Crystal.

Every step is Carpenter work, from a Lv 94 intermediate up to the Lv 100 finish, so one class covers the whole chain.

All 3 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Claro Walnut Lumber has the widest use: 82 recipes call for it, spanning six of the eight crafting classes.
