Welcome to SoM. Yes, many of the spells work. However, you might wish to learn the generalized basics before trying harder ones. And as with anything, use common sense when determining if a spell will work or not. Happy casting.
hi ^_^ i started on this site about 6 years ago, maybe 7, it's a great place for information, it still helps me in my studies. remember you need to always ask yourself if what people say seems logical. i mean, while certain spells and articles are worth your time, sometimes, they're just made up, if you have any doubts ask.
