this is for u to know sp needed :
http://nivlam.com/euro/this is to know how much sp u get on which gap :
http://www.nivlam.com/sp/when i was wiz only fire and ice i went 0 gap for lot of lvls then at 30 i needed teleport so i had sp problems ,and added some earth ,so now i need lot of sp to get all skills my lvl cuz now i also have cleric sub , i can take giants now

to wiz a sub is needed ,cuz we die alot ,bard is to avoid mobs mobbing on u with noise and u get speed to kill faster and lvl faster ,cleric gives u more defense so u don't get 1 hitted when u use bless and division and cycle ,with those 3 skills i tanked a 2h warrior ,but in the end he got a crit and i died ,and also there was a china man also hitting me at same time (CTF) of course i wasn't using life control
