It took me many wipes to do Utgarde on my Paladin team. I did fine out that the first boss, Prince K, is OPTIONAL. You can kill the adds, wait for him to pat left and sneak through the door. At least you can clear more if you're having trouble with Prince K until you get a little higher level and get some gear.

Big tips: Yes stay right behind your paladin. Take a big swing right turn into the room from the left side, so that you drag your followers behind you. This way your Consecrate is between the followers and the doorway that the skellies come in from. Losing aggro on the skellies? Use your AOE vs Undead spell: Holy Wrath. Your other AOE abilities (in my case Consecrationx5 and Divine Stormx5 - I was 5x Ret at the time) should take care of the Ice Tombs. The skellies repop where they fall. Since your AOE will kill them right near you, soon as they pop, re-cast your AOE's. Save all AOE for skellie repops.
