Cis forCrossbow
A crossbow is a weapon similar to a bow but much easier to use. Crossbows fire bolts while bows fire arrows.
The bow string on a crossbow is pulled back using a small winch or a rod and then held in place by a small catch, while a bow needs a very strong arm to hold the string back continuously until the arrow is fired. Crossbows require less strength and skill to use, and were a very effective weapon before the gun became commonplace.
