Some people are under the usumption that they can change their DNA to turn them into something they are not, if you are one of them, I am sorry but then you should stop using magick if that is the only thing you are here for, because you can not turn into something you are not, transformation spells are under the catagory fantasy because they do not work.
NOT SAYING THIS TO HURT ANYONE JUST GIVING ADVICE.
You can say any of those spells as many times as you want and you will get the same result....nothing. I am sorry if I affend some of you people who believe you can do it, but fact is fact. Your just fooling yourslef. You may believe in what you want, but let this gander in your mind every time you try to cast a transformation spell and there is not work.
