I have talked to a couple of Pagans about this subject. They tell me that while you could bring on a glamor to help with perceptions. But actual physical change would not happen. Then again, they also tell me to talk to so and so. Most also tell me to be careful about using spells written by others. The intent and mindset of the caster (and yourself) seems to play a important role in what results you get. Still something I look into from time to time.

Mostly, I think it is a good focusing tool, self-hypnosis. Good luck, I intend to post if I find out anything positive.
