I'm gonna try this method out, I was thinking it would be kinda cool to insert particle effects somehow but never gave it much more thought.
Oh and about improving the guide, the colour purple is horrible when reading.
I can't read it without highlighting the whole text, completely useless guide in that sense so please change that. And you could perhaps go and lighten up some keywords, for example
"search for cmd (for vista only i believe".
To have keywords on important steps is always good, some people may not know about that cmd command in Run.
Also, something you might want to add is if what kind of effect different spells would have? The FrostBolt.m2 is a missile type spell, which means it always stays on and don't decay. What happens if you pick something that do decay, maybe Rejuvenation for example? Or impact type spells which happens when a fireball hits a target and makes it go "poof" for a short moment.
Although, +rep since I'd actually wanted to know this so, good work
