Make 3 knights and bot them all at the same time wherever you want. After 2 days of botting you make a new char and lvl it high enough to kill the lowest level of the knights, continue killing all of the 3 knights you were botting and you'll be 200 in no time. NB! Level 150+ gets only 5x exp, while level 110 gets x15, so if you level a char from 100 to 120 and then kill it with your lvl 150 char, you basically get x15 exp also.
