Does a similar effect happen with the sword? When charging up and swiping?
Edit: upped server to 8 players
I tested it with all the weapons I was able to grab that being:
Magic Staff, Mace, Mace 2, Katana, Sword, Knives, Bow/Arrows and Boomerang.
As seen, only the arrows seem to twitch allover the place making them hard to use.
