I read that cool little story in Unwired about the technomancer that did not have any detectable EM emissions because she somehow concentrated on "not emitting". I cannot find this ability listed anywhere. Is she using one of the new echos like Blur or Immersion, or is any technomancer able to put their "biological radio on mute" by concentrating? Can someone give me a page number reference or post the rules for this so I can figure this ability out?
I think that the main power of technomancers is how sneaky they are, and I want to make my technomancer character as sneaky as possible.
