Lich King steady advance

The fight is a running gauntlet that requires you to stay ahead of the Lich King steady advance. As you flee up the escape tunnel he will cast Ice Walls in your way and send waves of undead after you. The undead are nothing you have not seen or dealt with before in the expansion, so just tank them to make Eve isk. Once the undead have been defeated Jaime or Sylvanias will destroy the ice wall and you can continue to move on until another is summoned to block your path. This continues all the way up to a terrace on the side of the mountain. The Lich King has cornered you. Just as he is about to attack, an air ship comes to your rescue and seals the tunnel.
