Riviera Partition

Taken all the way down to base materials, one Riviera Partition is 2 crafting steps deep and needs 2 intermediates — Elm Lumber ×4 and Yew Lumber ×4 — which resolve to 2 distinct raw materials totalling 24 units, plus 15 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 904 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 12 are burned by the intermediates, so the real crystal cost is 14 Wind Shard and 1 Ice Shard.

Every step is Carpenter work, from a Lv 16 intermediate up to the Lv 21 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, Elm Lumber has the widest use: 68 recipes call for it, spanning seven of the eight crafting classes.
