I think I'm doing it wrong.
The Rist Ambush is designated as a lvl 29 class quest but I'm almost lvl 33 Sorcerer and I still can't beat this one. I've generally been able to tackle most every quest using the lightning attacks but these ambushers just wail on me as soon as I enter the area, removing the static barrier for me and my companion (tried both Khem and Revel). I've only been able to kill one of the ambushers before the other 3 destroy me. What do I need to do to get past this?
