Well, Lair of Death in north Arwic is my favorite. Bugs give good xp and are fun too. You can also go to The DoC if ya want. The ravs and stalkers are decent points. Do this for a while.
Tuskers are boring.
But Great points. Once your lvl 40, things open up. Go to OHN, the acid vualt. You are good now. Go take it to the evil on the land.
