So just started a new barbarian for my second playthrough and apparently when i use Gaun's Pledge I heal my enemies through the Carnage ability???
I have attached a screendump where the combat log shows that the Glanfathan Hunters got healed by my character
I got the same problem. Didn't kill the messenger but she was gone after the battle. Searched the entire keep and couldn't find her. When I enter the courtyard i get a major rep drop with GV. Also Patch 1.04
