Sooo… When you will get a quest to get a tome from visions and it will point you to Trade District of Stormwind then you will be walking in circles searching for it?
The portal spawns after you kill him IIRC, so you’d have to come by in the window between the corpse despawning, the portal despawning and him respawning for this to be the intuitive route.
Yeah, obviously it’s to get back to the surface, which I realized after I used it but why the hell does it have a tooltip that says 0/1 val’rixx slain? It makes you think he’s behind the portal.
