So, i was messing around in Drak'tharon Keep and after the last boss i went down the shaftss that you land in water to exit. I was bored so when i got to the bottem, I decided to cast Path of Frost. People in my party were far away from me and not all the way down yet. So when they came in range, and fell down the last shaft they hit the water and died. This is due to the Path of Frost making all water act like normal land. Thus if they fell down the shaft, specifically the last one since it is taller, they would die. This is also use able in Azjol-Nerub after the second boss when you jump down the cavern.
Have fun killing your friends :wave:
