I tried my search-fu and didnt come up with anything but I came across an issue while reading something from another site.
In short it said that if a card or ability allows you to change the face of a dice to another facing with a different symbol, the new facing has to have at least one of the different symbols on it.
If this is true then if a card or ability that says change one of your "X"'s to a face with a HIT icon on it..theoretically I could change it to a face that had TWO HIT icons on it since it has at least one HIT icon.
I've always interpreted the reading as if it says change it to a HIT icon then you can only change it to a facing with a single HIT icon, otherwise it would have stated change it to a HIT HIT facing or etc etc.
any thoughts?
