Many years ago I grouped with a conjurer in Pillars of Flame. We killed a named mob, I believe it was in a cave, and my friend looted a staff that had a clicky complete-pet-heal. Don't recall if it was the result of a quest, or a rare mob drop, but I have not been able to identify that staff no matter where I search. I would ask my friend, but he died a few years ago in a car accident. Anyone have any idea what the name of that staff is?
Pretty sure you're looking for Yeddahd's Caduceus which is from living tombs and is a 40% heal for your pet. I'm not even sure if it still drops or not. I remember trying to farm it back during RTT and never getting it.
