FK IK Problem Solved

After a few hours spent trying to find a simple solution to keep the staff planted in the same place, but whilst still keeping the right arm in FK mode, I had found no solutions and therefore thought it best to just try and switch to IK for this particular animation where keeping it planted is important. To do this I had to un-parent the staff from the wrist control, delete all the animation keys for the wrist, hand/fingers, elbow, shoulder and clavicle. I could then set the FK to IK on the arm, reposition it to look as if it were holding the staff, and the re-parent the staff to the wrist.

Here is the video:

As you can see the staff now remains in place throughout the animation; the body no longer effects its chain of movement down the bone hierarchy.
