Rarefied Max-Potion

Nothing in this list is craftable in turn, so one Rarefied Max-Potion is a single step: 8 units of material drawn from 4 base items, plus 10 crystals.

That bill outweighs 5,254 of the 13,602 recipes tracked here and 1,059 of the 1,591 Alchemist ones, and 9,374 recipes nest deeper.

All 4 raw materials are gathered, and one of them is time-gated: Highland Oregano (0:00, 20:00). The widest gap between consecutive opening times is 20 Eorzean hours, about 58 real-world minutes.

Nothing in the data consumes Rarefied Max-Potion: it is one of 12 end products among the 15 Alchemist recipes at Lv 58.
