Max-Ether

Nothing in this list is craftable in turn, so a batch of 3 Max-Ether is a single step: 5 units of material drawn from 5 base items, plus 11 crystals.

That bill outweighs 4,201 of the 13,602 recipes tracked here and 826 of the 1,591 Alchemist ones, and 9,374 recipes nest deeper.

3 of the 5 raw materials come out of the ground, 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 Max-Ether: it is one of 104 end products among the 123 Alchemist recipes at Lv 60.
