Ballistics (Age of Empires II)

Like in the previous game Age of Empires, Ballistics improves the accuracy of Archers and Towers. It is important to note that it does not affect the artillery, including Bombard Towers, though an exception to this is that Ballistics does affect Spanish Cannon Galleons.
