The Mental Traveller is a special feature i created in the very first days of Buzz in the Matrix. It was a funny thing i had imaginated...but a way for me to use shortcuts between scenes in my early game tests.
I chosed to "freeze" this function after a while, but finally decided to have it available for Shaman players.
How does it work ? After you find the Mental Travel Totem, you are linked to the Mental Traveller. The power of the item creates link spots in the areas that enable it. Then you just have to concentrate on the spot (2 black inverted losanges), meaning clicking on it, to travel back to your original link place.
