Does the Visionary have line of sight to herself, and is she in radius 2 of herself?

Self-explanatory, really.

Hmm...it seems as if she doesn't have line of sight to herself if she's in cover, since she's not adjacent to herself.

I would assume that any given target will have line of sight on itself at any given time...

You might have to be more specific here.

If you are talking about some of her powers, she will not have LoS to herself. This was discussed a lot during PTing so hopefully someone else chimes in, or if you could define what you mean in relation to another card or character that would be helpful

Edit: She can't Twist the Ether or Wrest the Mind on herself if I remember correctly from PTing

EDIT: Hmm.

The wording of Foresight is important.

Foresight specifically counts out Visionary as a target for her power.  Any of her other powers that is any target in line of sight can be used on Visionary.

I remember that change to make it clear that she couldn't foresight herself.

But Twist the Ether and Wrest the Mind should work fine.

In playtesting it was explicitly stated that characters have LOS to themselves. I haven't seen anything that's changed that.
