If I did it was an honest mistake, but I In particular, I was referencing this:

"he would stop his run and turn on his heel. Spinning the bladed staff behind himself and completing a full bodily rotation"

With a special emphasis on the pivot of his heel, and 'full bodily rotation' are what led me to believe your character was spinning and not just the weapon. Unless you mean you did spin, it jjust started with the weapon, in which case I still would say Crystal didnt erect her shield until the actual physical [b]spin[/b] had began, not the motion leading into it.
