Blindness Effects

[Glim]

I was wondering if there could be a resist or succeed message added to the blindness spell. Right now it just says:

Some black soot glows briefly and a whisp of smoke rises from it.
Ok.

I know the logic behind this would be that there wouldnt be any way to tell if they can see or not. But I was just thinking that, realistically, if they were blind, it would soon be apparent after the casting of the spell. The person would be shocked/frightened/angry (these things cant always be seen if it is cast on a mob though) if you werent in a fight, if you were in a fight it would be even more so as they would be wildly swinging or tripping and the like.

Just thought this might help in the spell department.

Thanks,
