I am playing a paladin with some friends. Were used the old Heroes of Legend for backgrounds. I got 3lvls of Cleric in background. I created a character using the Gestalt add-on for my first 3lvls. Now I have just reached 6th lvl 3cleric/6paadin, but when I go to mercies it will not let me choose disease Mercy so I can remove disease. It requires 6th lvl Pally which I am. Any idea why this is happening?
