you really should come here if you are using eathena. if you are not.. i suggest you use it. there are guides where you can learn how to script a npc.
As for Exp config... go to conf folder look for battle_athena.conf and find it.
And as for items.. go to db folder and look for item_db.txt

thnx very much...:3dflagsdo
