how to defeat ragnar

I moved over to the left side of the screen as soon as I could and stood directly in front of the door in the background facing to the right. I then just kept blocking ragnars attacks , which always keeps coming from the right, until Lyra prompted me to press y to grapple ragnar. Press y repeatedly to win and as soon as you let go of Ragnar, hit him a couple quick times and then cover up. He will then move and then he will throw snowballs which will only come from the right as long as you stay in front of the door. He will throw four and then he will jump out at you again from the right and repeat. Repeat this from that position until he dies. You wil laugh at how sickly easy it is from there!

Right after the two bears are done talking, run to the left of the screen and keep blocking ragnar's attacks. Lyra will then prompt iorek to press y to grapple with ragnar. Do that after ragnar rams into iorek. Press y repeadetley to win. Hit him a couple of times after ragnar's stunned then block attacks again. Repeat until ragnar's dead.
