I've observed followers use staves that have spells from the Conjuration and Destruction schools of magic only. I am wondering if followers will also use [staves with spells from the other schools of magic][2] or [all of the special staves][3].

Which staves will be used by [followers][1], when given to them? Or alternatively, which staffs will not be used by any [follower][1], when given to them?

List of all staves and the school of magic its spell is in:

Note: [Staves can't be disenchanted nor custom enchanted.][5]
