What is your favourite spell in the Harry Potter universe?

I love the Expecto Patronum spell. I like the idea of having a spirit animal.

I really like Lumos. Simple, but effective 🙂 It also reminds of playing Dungeons and Dragons as a kid because it’s one of the first spells a wizard learns in the game.

I have to admit, I have NEVER watched a Harry Potter movie, and furthermore, am not really interested in watching one.
I like sci fi however this just does not appeal to me - perhaps as it was a children's book originally??

I don't know, because I've never seen any Happy Potters'! Sorry about that!
