If you got the character knight then up to level 60 then get on the map which is call The Ramparts on Hard then put some of his towers like on this video -http://www.youtube.com/watch?v=G1PIZQNO0AE this guy puts on Insine but don't look on the insine just look how this guy put his towers then do the same when you finish puting the towers change on another character for finishing it you should get up to 190,000 in about an 2 hours you gone have 70 lvl on one of your characters. Have a good exping on the hard it takes a lot of hours but gets better level on other characters.
