Thread: Excess Charisma

You can do what Talith said, and combine it with some math in such way, that you get your xp as close to leveling up and then do your highest charisma mission.
i.e. Two Pyramids (Level EXP won: 745) and you have lets say Next level in: 3xp

That way you will have 742/X xp on your next level and full charisma. (With this during low levels, you might be able to run through some levels without waiting regen)

Other option is, do some dailies, or awakening quests. They usually give lot less xp, but they drain your charisma nicely
