This is the "death jump" next to Nurn's Romp. I couldn't get myself to do it... Scary! There is a spot on the back side of the formation with some bail slings that you can rap down off of. Or you can rap off of the top of the Exorcist (I haven't done this yet, but supposedly it is possible to approach the top of Exorcist from the top of Nurn's Romp).
