Soloing Utgarde keep on a Pally?

I am trying to solo Utgarde keep on a pally at level. I can’t get past the first boss, Prince Keleseth. He freezes my toon in a block of ice for like 20 seconds while his minions beat on him. I can break it twice, but he puts it right back on and eventually he goes down. Any suggestions?

Edit: So I found a solution. It was to take a Free Action potion at the beginning of the fight. That made him immune to the freeze for 30 seconds. That plus the pally Divine Shield and a break stun trinket to break the stun twice, and he had enough up time to down the boss.
