Oasis Half Partition

Taken all the way down to base materials, one Oasis Half Partition is 2 crafting steps deep and needs 2 intermediates — Mahogany Lumber ×3 and Walnut Lumber ×3 — which resolve to 2 distinct raw materials totalling 18 units, plus 30 crystals.

That bill outweighs 7,380 of the 13,602 recipes tracked here and 740 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 21 are burned by the intermediates, so the real crystal cost is 26 Wind Shard and 4 Ice Shard.

Every step is Carpenter work, from a Lv 25 intermediate up to the Lv 40 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, Walnut Lumber has the widest use: 128 recipes call for it, spanning eight of the eight crafting classes.
