You should know that this game is level based, meaning the bigger the difference between yours and the enemies level the more damage and EXP is effected. You should spend time killing all the goblins in the area. By then you should be level 4 or five. Once all those enemies are dead, then you should take out the ones in the other areas, such as the ones in the caves and dungeons. After that's all done you should have an easier time dealing with Arben.

Do you want to play as a pure Warrior or a Battle Mage?
