expecto patronum

Expecto patronum is not my favorite because I find in useful in real life. Like if there's going to be magic around, I wont be able to use it to get rid of dementors because dementors scares me and if they come, I'd rather hide. haha! My favorite spell in the disarming spell, Expelliarmus! haha! I think it is a very useful spell because all you need to do is the disarm the opponent then once he doesnt have his weapon anymore then you have all the advantages. You can already attack from one side to another.

tough question, I like muffliato, for privacy. I also would like wingardium leviosa. Of course expecto patronum is very helpful to know. What I really want is an invisibility cloak.

I also like expecto patronum, cause its a very nice protective spell!
