Weaponsmaster

The Weaponsmaster plays a role and is encountered during the Shield of Arrav quest. If you are a member of the Black Arm Gang he will attack you. The Weaponsmaster will attack you if you attempt to take either of the two available Phoenix crossbows (both are needed to complete the quest). As a result, he must be killed in order to get them. He will also attack members of the Black Arm Gang if they try to talk to him. He is found upstairs in the southern alley of Varrock.

If a member of the Phoenix Gang tried to take a crossbow, he will notify them that it belonged to Straven and prevent them from taking it. Members of both gangs, or even those not in either gang, can cast Telekinetic Grab once they arrive in the weapon store room to take these crossbows, but may be noticed if you have already spoken to him.
