A catapult with an edge, this weapon was often used to throw large bolts at opponents, hence it was often known as a larger-than-life sized version of a crossbow. Unlike the mangonel which uses a string to project objects into the air, ballistas use bowstrings, hurling huge arrows that can rip through a row of soldiers, or break through an enemy fortress. Highly accurate, this weapon could take aim at targets over 500 yards away and deliver massive damage.
