First of all, welcome.
I think you would be better off doing the research and then practicing and casting your own spells. You put your own energy into it and it betters your odds of the spell working. Just so you know any spell that says it will change you into something or someone else or make you grow animal body parts (like a tail or wings) wont work. They are fake spells so just be careful when you look through the spells here. A lot of them wont work. Just use common sense. If it sounds like something out of a movie or book it wont work. Just something to remember when reading the spells section.
