As probably very well know, you can buy black potions in the Minotaur Labyrinth in Ravage Roaming and at the alchemist shop on Regna Island. It seems that at a certain point, black potions seem to stop permanently raising your stats (might, accuracy, etc.) and simply do nothing at all. It seems like I usually can buy one or two for one stat and then they do nothing at all. What is the limit for black potions, and is there anyway around that?I notice that you can still use a barrel to raise the stat further.
