Potion of Vitality

Nothing in this list is craftable in turn, so a batch of 3 Potion of Vitality is a single step: 3 units of material drawn from 3 base items, plus 2 crystals.

That bill outweighs 3,373 of the 13,602 recipes tracked here and 426 of the 1,591 Alchemist ones, and 9,374 recipes nest deeper.

2 of the 3 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Nothing in the data consumes Potion of Vitality: it is one of 3 end products among the 4 Alchemist recipes at Lv 18.
