At 52 I was in the cemetary. Around 56 to 58 move to DC and kill the archers, doom scouts and grave liches. These mobs also drop stolen inf ore so make sure you have the quest. Once they are light blue move to the field west of that area right by the castle its self for the harder doom mobs. They use alot of magic so be sure to give the proper prof buffs. Around lvl 62 you should be able to go to the area behind the cemetary.Sorry forgot its name. The doom Knights up there are great XP but you will need majestic light armor or you will be stunned none stop there. There is also a quest to get A grade recs there so take advantage of this as well.
