Bonestorm cancel

As handy as this would be for me to keep a secret, I just discovered that tapping the spell, briefly releasing, and then pressing and holding it again with a simple enough timing on each step, the movement slowing effect is undone entirely, allowing you to move at full speed while charging an extremely strong spell. I'm unsure if other spells like this have the same problem considering the unique animation of bonestorm summoning objects before throwing them.
