Okay I was looking around the website and i saw that Professor Greyrose's favorite Attack/shield was a tower shield and i disagree. I hate tower shields because whenever i try to do my attacks there is always somebody who uses a tower shield :x Professor Greyrose can you tell me why its your favorite attack/shield
It makes sense for an ice professor to like tower shield, since that's the main ice spell that pushes people to spend some training points in the ice school. Getting volcanic shield along the way is useful, too, I guess, but the anti-fire and anti-storm shields are available by other means.
As for why you don't like tower shield, it sounds like that's because it's effective.
