Far Eastern Indoor Bamboo Fountain

Taken all the way down to base materials, one Far Eastern Indoor Bamboo Fountain is 2 crafting steps deep and needs 1 intermediate — Growth Formula Kappa ×2 — which resolves to 6 distinct raw materials totalling 21 units, plus 30 crystals.

That bill outweighs 8,152 of the 13,602 recipes tracked here and 815 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 14 are burned by the intermediates, so the real crystal cost is 14 Water Crystal, 8 Ice Crystal and 8 Wind Crystal.

The chain crosses two disciplines — Carpenter to Lv 90 and Alchemist to Lv 76 — so no single class can finish it unaided.

4 of the 6 raw materials come out of the ground, and one of them is time-gated: Bamboo Stick (7:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Growth Formula Kappa has the widest use: 40 recipes call for it, spanning four of the eight crafting classes.
