Waterfall Partition

Taken all the way down to base materials, one Waterfall Partition is 2 crafting steps deep and needs 2 intermediates — Chondrite Ingot ×4 and Integral Lumber ×4 — which resolve to 5 distinct raw materials totalling 52 units, plus 128 crystals.

That bill outweighs 12,890 of the 13,602 recipes tracked here and 1,366 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 64 of those crystals go into the final step; the other 64 are burned by the intermediates, so the real crystal cost is 32 Earth Crystal, 32 Fire Crystal, 32 Ice Crystal and 1 other kind.

The chain crosses three disciplines — Armorer to Lv 90, Blacksmith to Lv 88 and Carpenter to Lv 88 — so no single class can finish it unaided.

All 5 raw materials are gathered, and one of them is time-gated: Prismstone (4:00, 16:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Chondrite Ingot has the widest use: 210 recipes call for it, spanning seven of the eight crafting classes.
