I noticed something today (for the first time) that further demonstrates the linkage between Esk and the staff even before she becomes a wizard. After Granny (with the aid of the staff) rescues Esk from being stuck as an Eagle, Granny says to her, as she gives her the staff "Here. It's yours. Take it. I just hope this is the right thing to do." Terry says that's not at all the way an apprentice wizard receives a staff but by sheer coincidence Granny got the essence of it.
Esk's reply is "it's very nice," she said uncertainly. "The carvings are pretty. What's it for?"
To the best of my recollection no one else can make out the carvings, let alone think them pretty. Directly thereafter, Esk ignites the fire, the fireplace, chimney, etc. but while she is holding the staff she only uses her fingers.
I think this fits with the fact that the staff continues to protect her until she childishly discards it, but that when it becomes her staff as a full wizard, it is simply a blank staff--almost a stick.
