Rarefied Growth Formula

Taken all the way down to base materials, one Rarefied Growth Formula is 2 crafting steps deep and needs 1 intermediate — Persimmon Tannin ×2 — which resolves to 4 distinct raw materials totalling 10 units, plus 15 crystals.

That bill outweighs 5,754 of the 13,602 recipes tracked here and 1,122 of the 1,591 Alchemist ones, and 4,464 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 5 are burned by the intermediates, so the real crystal cost is 10 Water Crystal and 5 Lightning Crystal.

Every step is Alchemist work, from a Lv 66 intermediate up to the Lv 68 finish, so one class covers the whole chain.

All 4 raw materials are gathered, and 2 of them are time-gated: Perlite (20:00) and Windtea Leaves (16:00). The widest gap between consecutive opening times is 20 Eorzean hours, about 58 real-world minutes.

Of the intermediates, Persimmon Tannin has the widest use: 5 recipes call for it, spanning three of the eight crafting classes.
