I might be wrong with this but if you get it exact when manually making potions, no mistakes, you get more potions, seemed that way when I was making a few yesterday as I don't have a perk to make 3 of a kind yet but got an insane amount of potions when doing it exactly right.,(reply>), I think if you follow the recipe perfectly it gives you three. and then you can take a skill to make it 4 instead of 3,(reply>), DraigUK yeah you're right so many YouTubers miss this
