When a unit with Missile Immunity is struck by a File:Icon Ranged Bow.png , its Defense score is temporarily set to File:Icon Defense.png for the purposes of blocking this damage. This means that it is exceptionally difficult (though still possible) to inflict Damage to this unit using a File:Icon Ranged Bow.png . Missile Immunity does not work against other types of Ranged Attacks, such as File:Icon Ranged Magic.png or File:Icon Ranged Boulder.png .
