Many of the visuals for spells are hardcoded and can not be applied with EffectVisualEffect.
I could be wrong but I'm pretty sure this is one of them. Pretty much any effect that has to be directed towards some object, is an effect that can not be individually applied. The only ones that can do this are the beam effects. It's too bad they didn't include the gaze, cone of cold, burning hands, etc..in with the beam effects so that they could be applied the same way.
