Here is a site that will offer the skill changed that come when you choice heaven or hell when you reach lvl 89. be sure to look at each skill before you make a choice this changeed to every skill will be important depending on if you choice to go more pvp vs. pve. Also be advised that once you choice the side you want to be on... you actually have to loot/buy the books that will change the skills.... hope this helps as each of us get closer to that really high lvl status
