I've completed my quests with my level 52 Necromancer online. Is there a way I can restart my quests or go back and replay them? Can I still go back and fight bosses again? Can I join others' quests and help them do it? I see alot of people doing Baal runs, diablo runs, trist runs - what is that all about? Sorry for all the questions, but I'm pretty new to all this and need the help...just wondering how I can keep playing and level up after I beat the quests for the first time. Thanx very much!!
