As said above, you cant master anything. Ever. You are always learning!
And as WhiteRav3n said above, you cant change your physical form. You are human and always will be- spells dont change that.
Spells that dont work include:
Turning into a vampire/werewolf.
Turning into a mermaid.
Turning into a faerie.
Super speed spell.
You get the idea. If you want to put yourself under the illusion that you are a vampire, try lucid dreaming. Lucid dreaming is dreaming while you know you are dreaming; and controlling your dreams. So, you can dream that you are a vampire. Its very real-like.
You could also try trancing, but that is harder and more complicated for a newbie.
