As Jharib touches the golem it thrashes a moment then still again and you notice it has frozen with its head looking at something. Some quick trials reveals it is fixated on Jharib, his pouch, and emptying it, the keys taken from the wizard. But it does not talk.
The fight was loud enough that you assume were there another golem patrolling the tower interior it would have come by now. You are currently on the 2nd floor of the wizards tower and have retrieved the rod as well as having found a vial and amulet. The rod and amulet seem related while the vial appears to be a protective potion, though you are uncertain.
