Yup, whenever Blizzard implements a class specific quest chain (such as the Green Fire Quest chain), they like to implement non-combat centric mechanics like using the Eye of Kilrog spell to see the invisible walls to the maze. And also, desummon your demon when running through the maze because even if your demon touches the wall it’ll punish you.
I wish I finished the Green Fire quest during MoP (obviously not this character), but I was not good enough to beat Ebonlocke when the content was current. I could have gotten myself a neat title.
