Scripts

Shiroyasha2910, regarding combat scripts, there is an excellent guide from the respected }{0TT@6bI4: combat scripts - guide
And regarding your idea, I haven't done anything like that myself yet, but as I see it, you should try using the HasHeroSkill() function, and save the result in a variable using the SetGameVar() function, and then retrieve it in the combat script file using GetGameVar(). There might be another way, but this seems to be the most obvious one.
