Thought this might be useful to any builders that need a quick reference to the experience charts to level up. I got 1-20 from the Hordes of the Underdark Official Strategy Guide. From 20-40 all you do is take the amount of xp, add 1,000, and then multiply it by the level and you get the next level's xp…and so on.
