As part of the quest, the player must augment Zanik's existing crossbow with additional items, reassemble it when broken, and then use its special attack to defeat the Bandos Avatar. During this time, the crossbow itself cannot be equipped. Instead, a dialogue option allows use of the special attack.
The special attack, Defiance, uses 50% adrenaline and deals increased damage against monsters and players who are using prayers or any god-related equipment. When the special attack is used, lighting sparks out from the crossbow as a lightning orb charges up and is fired, pictured right.
