Yeah, my advice when you're new is to just keep playing through the quest line. Items get better and you start getting a lot (relatively) of orbs/scrolls to drop. You're probably not going to get super mega awesome items at level 20 so just keep leveling because the higher level items are more likely to be good.
Personally, my witch is only 40 and I still feel like items of my level are largely a waste of time. Did find my first unique on brutus, though (wondertrap).
