There are 2 phases to beating Blizzeta. (first phase), Blizzeta is in a form almost looking like a giant egg. Go near the wall (where you won't get hit) and take out your flail (a.k.a. ball and chain) and keep throwing it at her. She will get smaller and smaller. (phase 2) Blizzeta will shoot these ice chunks at you just keep running and she won't hit you. Then she will surround you with the ice chunks. Before she surrounds you with them take out your ball and chain and right when she throws the ice chunks surrounding you, throw the ball and chain and run out of the way. She will then drop herself in the middle. Now throw the ball and chain at her. (If you get hit from being surrounded, you will get hit and break one of the ice chunks. It's easier next time through).If you hit Blizzeta 3 times, she will be defeated.
