Making a note here so I remember to look at this later:
"Special Ability Factor Confirmation" is so long that it makes the window overlap the stat mod window, so rewording it would probably be a good idea.
I'd go with either "Check Special Ability Factor" or simply "Check Special Factor".
We might also want to change "Success rate" to "Success %" if it is a unique string for this window.
Also, the text at the top of the window might need to be line-broken differently, if possible.
