A/N: Aand that it is it! This book is over! All the spells ever seen or mentioned in the HP universe. I hope you found this helpful!
I might make a book similar to this on potions, as well. If you have any requests for books or any questions about anything, feel free to ask. You may pm me or comment below, which ever you prefer. :)
C'est la vie,
