Pivot problem resolved

I have found a solution my pivoting problems on the staff and wrist; to slightly change the animation. After a few days of trying to find a solution to the problem I finally came to the conclusion that it was probably something only a technical artist could resolve, a character rigging artist, and so decided instead of spending more time trying to fix the issue I thought I would find a way around it. To do so I slightly changed the animation, in the sense that instead of the staff rotating forward slightly before bolting backwards, I would instead have the whole staff jerk forwards before the backwards motion. It looks believable and so I am not too annoyed at not being able to fix the pivot problems, and it now allows me to carry on with my work.

Staff and hand move forward before the being struck action.

Struck action - no pivoting issues.
