Help, Two Worlds leveling up?

Right, I'm trying to get to level 50 for the achievement on two worlds. I'm currently on level 26 and I'm finding the level process quite slow, so I was wondering if there are any ways to level up quickly on this game?

I have been doing quests but there only giving me 250 exp while I need 1000 now to gain a level, monsters don't really give you alot of exp. Those are the only ways I know of how to level up on this game.

Thanks alot
