[Help] Model Editing X-Spell to Levitate

[Vanoc]

I did search for this but didn't find anything. I am trying to change Ice Barrier to Levitate and its not working it will give me that cloudy stuff at my feet when i very first cast it but that is all. Is it impossible to get the hovering affect that priests do when they use this spell? Edit: kinda just woke up...i didnt really post a question at all, well i was wondering if anyone could lead me to or give me the spell id of the spell that allows the priests to float.

Thanks ahead of time -.^
