yeah its not that hard. all you have to do is keep fighting him until his health drops to between 990400 and 990100. once you have him there use break and hopefully after everybody on your team gets a turn his health is well below 990000 and once he stands up after break and its your turn use subversion and hpefully your teammates dont bring his health back to above 990000. when its his turn he'll try to heal himself by 2000000 and since subversion is in effect he kills himself.
