The focusing chamber is an item requested by Oldak as part of a plan to stop Bandos from invading the city. It can be obtained from Turgall from the Dorgesh-Kaan power station found south of the city.
It is used along with the energy projectors to modify Zanik's crossbow so it can damage the Bandos avatar. During the fight against the avatar, the chamber is broken off the crossbow and must be reattached to the crossbow.
