White Rectangular Partition

Taken all the way down to base materials, one White Rectangular Partition is 3 crafting steps deep and needs 3 intermediates — Cut Stone ×6, Mortar ×3 and Distilled Water ×3 — which resolve to 4 distinct raw materials totalling 30 units, plus 30 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,694 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 21 Wind Shard, 6 Water Shard and 3 Fire Shard.

The chain crosses two disciplines — Goldsmith to Lv 30 and Alchemist to Lv 20 — so no single class can finish it unaided.

All 4 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.
