Would be good to have the good sheild repel attacks and the fiery one absorb them. For example someone hits you with an arrow when your good and it bounces off, when your evil with a fiery sheild it burns the arrow to dust. Simple things like that, that would add to the feel of each alignment.
that would be cool if you could do that with spell. i hope in fable2 that you can use mutiple spells at once. that might be neat to do.
