How to use Potent Concoction
CalculatedPotent Concoction makes each Ferrofluid Flask restore Nephtoglobin on top of Health: 20% at rank I, 30% at rank II and 40% at rank III. The game holds only two copies, in chests in Valley of Ashes and Fortress, so rank III needs Perfect Copy, which raises every other equipped rank I or II Amber by one.
It lets a hybrid build heal and refuel with one drink, so pair it with Bottomless Well and Tomorrow's Promise. Butcher's Carnage is a hard conflict, because it stops flasks from healing at all.
Written from the Amber's own parameters, where its copies are placed and its listed pairings; rank II values marked as interpolated are estimates between rank I and rank III.
