you are wasting your time guys.the xp/sxp are server sided..no point in tring to edit them.
lets see:
1: edit your exp points(on character menu-and the exp bar) and you will edit it to like 9998/9999 .next time you get 1~2 more exp points on your PC you should level up but on the server you will remain on the same level.that leads to a crash.-no point for editing skill points-only to showoff xD
2: edit the mob xp/sxp/drop/etc.when you kill the monster on your client you get a specific ammount of xp/sxp/etc but on the server those things have other specs.so when you lvl up either on serverside/client side you get a crash.
in the level/skill grinding MMO's you will NEVER be able to edit those stuff because they are always server sided.just quit the ideea and try to get an AoE/speed/dmg hack that allows you to kill more/faster/safer.
