Wood Slat Partition

Taken all the way down to base materials, one Wood Slat Partition is 2 crafting steps deep and needs 2 intermediates — Lignum Vitae Lumber ×8 and Sandteak Lumber ×5 — which resolve to 2 distinct raw materials totalling 52 units, plus 105 crystals.

That bill outweighs 12,890 of the 13,602 recipes tracked here and 1,366 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 91 are burned by the intermediates, so the real crystal cost is 98 Wind Crystal and 7 Ice Crystal.

Every step is Carpenter work, from a Lv 76 intermediate up to the Lv 80 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, Lignum Vitae Lumber has the widest use: 134 recipes call for it, spanning seven of the eight crafting classes.
