Zanik's crossbow (broken)

Zanik's crossbow is a quest item used in The Chosen Commander. While fighting the Bandos avatar, Zanik tries to use her crossbow's special attack, but the avatar breaks it, scattering the broken crossbow, energy projector and focusing chamber in the surrounding area. After killing three statues, you can pick up those pieces and repair the crossbow, making an upgraded Zanik's crossbow, which is used to finally defeat the avatar.
