Potions of Potential -stat- behave oddly with items that increase -stat-
Potential Maximums are increased based on current stat instead of actual stat if potential max is below current boosted stat level
I was playing a Mist elven duelist with a toughness stat at 11 and potential max of 11. I drank a blessed potion of potential toughness while wearing bracers of toughness +4 for a total of 15 to. Potential toughness was raised from 11 to 17. This may have been caused by a bug fix relating to stat potentials.
