I HAD TO TRAIN FOR AT LEAST 4 DAYS TO BEAT HER. I HAD 3 CHARICTERS WITH PROCTION FROM ZOMBIE AND BEFORE I KILLED HER SECOND FORM I WHICHED THEM FOR 3 OTHERS ALLOWED THEM TO BE ZOMBIED AND KILL HER SECOND FORM. I USED THE AEONS IN THE THIRD WITH THEIR OVERDIVES AT MAX I ALSO HAD THE PARTYS OVERDRIVE AT MAX (I DO THAT BEFORE ALL BOSSES).
