I'm not sure what to call this properly or how to search on it so I apologize if this already covered.

While playing the game you can hold control while hovering over a unit in combat. It pulls up a bunch of stats, all of which have question marks in them for me (that is, no information given, all ???? for answers).

My question is: How do you improve this display? Is it perception -based? Some other skill? I had 6 perception for the first fight (so +1 from base) and I didn't get a scrap of information from the enemies.
