Square Niche Partition

Taken all the way down to base materials, one Square Niche Partition is 2 crafting steps deep and needs 2 intermediates — Pewter Ingot ×5 and Red Pine Lumber ×2 — which resolve to 4 distinct raw materials totalling 50 units, plus 72 crystals.

That bill outweighs 12,777 of the 13,602 recipes tracked here and 2,069 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 56 are burned by the intermediates, so the real crystal cost is 64 Wind Crystal and 8 Fire Crystal.

The chain crosses two disciplines — Goldsmith to Lv 86 and Carpenter to Lv 84 — 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, Pewter Ingot has the widest use: 63 recipes call for it, spanning six of the eight crafting classes.
