A guildie and my alt are on this quest, we get the horn pop and at 10% we imprison Inhibrius soul, kill him and do not get credit. We have tried to have just me do it/him do it/ both of us at same time/ and even spam it until it dies. We have reset the instance 4 times and dropped the quest twice and cleared the dungeon twice and we have tried killing the the last boss and going back and then popping nothing has worked any Ideas or just bugged?
