Skadi is toast! First attempt tonight.

The trick was in fact making sure all the adds are taken care of first before pulling boss. What this meant was that I had to wait until the third or fourth pass while I cleaned up casters and harpooners. It was piece'o pie after that.

Went on and one-shotted the King. Then cleared all of HoL for the first time; got Loken down first attempt ever (even got the 2 minute kill achievement).

Everything else just seemed so much easier after Skadi. That encounter really helps you fine tune your reactions and toon coordination.

Thanks again for all the help.
