go to the land of the dragons, into the throne room, exit into the hallway where there are those horsemen (assault riders... i think) turn into master and whip ass, as much as possible, if u kill all the horsemen u should get like close to 150 xp every time, go back to the throne room b4 your drive is depleted and teleport out of the world then go back and repeat, took me like 30 min to go from lvl 3 to lvl 7, mad easy, equip form boost so ull stay in drive for longer
peace
