From time to time I use my eye of kilrogg (glyphed) to look for chests because I carry 2 keys around with me and that kinda buggs me and I dont want to throw them away. So I just did a small fly through with the eye and when I entered the room with the white walls that we normaly have to deactivate first, they werent there. With the quest they are there for sure.
I´m sure this is useful to do the quest abit faster like place the demonic circle before getting the quest right at the last orb or in the corner of that room and port from the room with the walls into the vault.
I´m not sure if this counts as exploiting because quests arent supposed to be done like this.
The eye gets nerfed with 5.2 so use it while it lasts.
Glyph of Eye of Kilrogg - The casting Warlock must be within line of sight of the Eye of Kilrogg to place the Demonic Circle.
