How do you beat the queen of ice in enchanted arms

simple NEVER use golems agenst her or you will die always put some one in frount of atsuma because he takes the most damage <because he is fire> always put yuki at the left or right hand side <so she can use mega drum roll> and put rigar or karin in frount of atsuma ALWAYS have some one or some thing to heal your party also power up when you start fighting and you must be at lv 50 or over to beat her it also depends how much ep and hp your charicturs have
TIP:BECOUSE ATSUMA IS FIRE TRY TO USE ALL YOUR EX MOVES FROM HIM ONLY TO DESTROY HER<Queen of ice>
