Hello,
I am trying to modify an ability to only affect Bretonnia's peasant class troops. I figured it would be under special_ability_to_invalid_target_flags or something but the closest I could find was targeting ground or air troops. I want the ability to only affect peasants so that includes the mounted Yeomen, but if I can't do that in the game then I would want to target only infantry as that would at least ensure that the Knights are not affected. Anyone have suggestions on how to make my ability only target peasants? Or failing that, only target small?

Also on the subject of that, is there a charge bonus vs small? Or only charge bonus vs large/All

Thanks
