Sorry I don't speak German, somebody might have to translate this if you don't understand, but in Inggison I follow the road to the south (passed the entrance to Taloc's area), there's a river down there. I set my bot to go back and forth from end to end. It's not traveled very often, and has many non-aggro monsters.
Just be careful of the very end: There's a circle thing that will blow you up to the level above. Make sure your bot's path doesn't go through that, or it will mess you up.
