Request for guidance involving beams of light!

Bah posting here since I got kicked out of shear stupidity... I just want to know where can I base the model on, not have someone doing it for me ~_~

How hard is it to understand??

I'm thinking of making an ability like the one below;

Marisa - Final Spark http://www.youtube.com/watch?v=0K-ZpO609Fg

a blast of energy that comes forth from nothing and stays there for any period of time (channeling, of course, but my question is about the model itself). I've seen in it done in a couple of maps, so I know it is possible.
I'm not requesting anyone to do it for me, just begging for guidance on which model to base my spell on (yes I can use unit editor by Magos)

I'd thank you with all my heart


FOR MARISA!!
