So I was bugged by death grip in Thaldraszus zone and couldn't do a thing. I unstuck my character through battle.net website.
It teleported me to secret place I believe I shouldn't have any access to.
First I landed in the giant hall blocked with star-wall. On the other side there is a blocked entrance. In the middle there are two teleporters to different rooms. Across every room there are consoles associated with each of the four elements:
See screenshots below:
First room using teleporter presents minature versions of all Primal Incarnates and their eggs on the walls:
Second room presents first aspects holograms (Malygos, Alextrasza). We can see that it's still under development given unknown cubes:
Let me know what do you think it might be!
