Well, guess what! ITS EASY! get to level five, usualy i just take Zorbak's chipped tooth quest and the first 2 Artix quests and go to the bridge map. Kill undead untill you have 10 Chipped Tooth. Then go and kill the Boss, Tele to Battleon to drop off the tooth and get the quest again. then tele to SwordHaven to complete his quest. Just repete that, you will be getting 100 exp/Gold each time you do the quest plus what you get for all the kills.
Once level 5+ do Artix Last quest repetedly. this quest gives you 1k Exp/Gold so it is the best EXP giving Quests so far. I am level 9 using this method.
Take Care all!
