Umm no, you too seem to not know what shapeshifting is. Bryson does realize, what extent of magic is possible. He is an elder witch,(wise man/woman) to me. Sorry, if that seems rude. He is very respected on SoM, and a helpful person.
First off, you can't do the impossible. It's not in anyway, a ability. What your doing, or (claiming) to do, is referred to as fluff! So, what is fluff, you may ask? Well here are some examples.
*Claiming to be something/someone your not. Ex: (bird, fairie, truck, vampire, and oh my, a mermaid! ect)
*Claiming to do the impossiple. Ex: (killing someone from a spell, eye changing, flying, skin color, ect)
*Having little sense of knowledgge on the craft, arguing that your right, ect.
And the list goes on! I suggest to learn the basics of magic. Try reading, the posts in the about magic, section. Ground, visualize, and learn.
