For the prince I basically hugged the tank . Kept everyone in close and dropped magma totems.

My healer might have been busting some of the frost tombs - but on the occassions he was frost tombed I
didn't do anything to break him out other than the magma totems.

I know others have specific /target lines in their dps macros, or a seperate target macro that they hit , but this was a spur of the moment run. By hugging the tank it makes it easier for the tank to gather the skeletal adds up, and the magmas take them down quickly.

I seem to remember Prince Keleseth doing ranged attacks with shadowbolts, but when everyone was close in I was either missing them happening (as they don't have to travel far) or they didn't happen. (plus the pally put shadow resistance aura up).

On the twin bosses (second boss in Utgarde) I also hugged the tank to minmise the charges. Popped fire elementals and burned them down.
