I just re read the description of "zone" and it seems much too powerful to me :
"Maintaining area enables the psychic to use any other Telepathic power on all subjects within the radius ..."
does it mean that one you maintain éarea", all the telepathy/sentience powers you use after cover the area?
The French text is even worse : "as long as this power is maintained, it allows use of any other Telepathic power on all individuals present in the radius indicated by the reached difficulty" ...
how do you people use it?
