Really cool; I think I could actually see this in-game. Indeed it is clear & colorful. I kinda wish you had used some variant of Anti-Magic Shell (or rather, done more to differentiate it), since these could look weird next to each other.
Related & unrelated to that... Different colors plox? That would take this over the top. That, and may I have permission to edit? Aside from colors, I could see myself needing a good "toggled magic immunity" spell in the near future (for da Trolls, of course ;P), so I might want to make that.
4/5 (5 for different colors/toggle). Many thanks. : )
