Since I’m trying to be a true blue potter head and die hard fan as well, I searched for the list of all spells used/said/done both in the books and in the movies.
To my surprise, there are really A LOT of spells from A-Z. Not only that, some of them are really hard to pronounce haha. But if you wanna be like them, then so be it.
Get your tounges and wands ready: “Alohamora” to the book of spells! ;)
