Which staffs will be used by followers, when given to them? (Alternatively, which staffs will not be used by any follower, when given to them?)
I've observed followers use staffs that have spells from the Conjuration and Destruction schools of magic only. I am wondering if followers will also use staffs from the other schools of magic or all of the special staffs.
List of staffs and the school of magic its spell is in:
