At level 60, each non repeatable quest that rewards Combat EXP will give you approximatly 1.3% of your level. This is an excellent way to level if you are tired of grinding and is faster than grinding at later levels. Through a series of riddle-laden quests, you can obtain the Chenga Tome, which adds 30% to Combat EXP obtained through quests that reward Combat EXP. The Adventurer’s Tome can be upgraded through a questline that begins with the quest, Hoom’s Song, given by Aljal who is stationed on Macalod Hill in Drieghan.
