1) The first animation, "Wand Fling", does the wind-up and points the wand forward, holding it there until stopped. Priority: 6.
2) After your spell is complete, "Wand Fling Release" returns the avi to a regular standing position. Priority: 6.
(There is no delay in starting the animations. The delays in the demonstration videos are caused by the time it took to start the video recording and then activate the animations.)
