Most people will say squad runs, but since you asked on the forum, I can explain.Short answer, most exp gained will be by running PV solo.The box above your chat window will show the amount of exp/spirit that you gain. Though on EPW, since the exp rate has been raised, that little window can't calculate past a certain extent (somewhere exceeding 60k exp). Once that point is reached, it will roll over and start again. When this happens, it will show that you're gaining more spirit than exp. This is wrong. It's quite impossible for the game to give more spirit than exp at any given time (unless at level 150, where you gain no exp at all).In a sense, that window will lie to you. For those that disagree, I'd like for you to go into pv (if you are under lvl 150) and write down the last 6 digits of your current exp. Once done, kill one (only one) monster, then write down your new last 6 digits.Subtract the first 6 numbers from the second set. There you will have the exp that you ACTUALLY gained. Compare that number with the number in the window above your chat box.Point proven.= Long answer
