Rattan Partition

Taken all the way down to base materials, one Rattan Partition is 3 crafting steps deep and needs 4 intermediates — Red Pine Lumber ×5, Mortar ×4, Annite Whetstone ×3 and 1 other — which resolve to 6 distinct raw materials totalling 57 units, plus 136 crystals.

That bill outweighs 13,047 of the 13,602 recipes tracked here and 1,404 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 64 of those crystals go into the final step; the other 72 are burned by the intermediates, so the real crystal cost is 96 Wind Crystal, 32 Ice Crystal and 8 Water Shard.

The chain crosses three disciplines — Carpenter to Lv 90, Goldsmith to Lv 86 and Alchemist to Lv 20 — so no single class can finish it unaided.

All 6 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, Mortar has the widest use: 140 recipes call for it, spanning six of the eight crafting classes.
