The Ice Magic Beast automatically reflects all of your magic attacks. Not only that, the Ice Magic Beast has some brutal freaking attacks. All-Aquara hits everyone for hundreds of damage. Forcea will hit one person for what may well be over 1,000 damage, and Trample isn't all that much nicer to you. Not only that, Ice Magic Beast will try and freeze you. Solve that right away by wearing a Warm Vest, or using a blazing ruby. Aside from knowing his attacks though, you'll need to know how to do some damage of your own.
