Oh man i wish you would of waited man or posted yesterday that you were going to do so, I have to chars under lvl 10 with the boost still in theyre inventory, and i would of worked on them instead of my alt char ive been playing as. If you have any other chars with it save it, or at least post a day a head of time of when you think you might use it, and ill make sure to have a char within 5 lvls of you so we can party up and watch the exp climb!! lol.
