Most Powerful Harry Potter Spells

The Top Ten
1 The Killing Curse
2 Imperius Curse

If you can control people then you can use them to use other curses such as the killing curse and you will not likely be blamed. This is why it is so powerful.

3 Cruciatus Curse
4 Sectumsempra
5 Confringo
6 Expulso

I like this spell because of the incantation itself and it launches people off their feet.

7 Expelliarmus
8 Wingardium Leviosa

First years knock out a 12 foot mountain troll.
Sure it was called dumb luck, but Hermione had to lie to Professor McGonagall, because there was no other way to stop Harry and Ron from getting expelled.
They needed to rescue Hermione.

9 Accio
10 Expecto Patronum

It keeps away the darkness which boils within us. It keeps you sane. It lets you keep your SOUL, buddy. and it looks cool lmao

The Patronus is a symbol of happiness in the darkness that takes over us sometimes.
A true symbol of a positive altitude.

The Contenders
11 Levicorpus
12 Slugulus Eructo

So that's the name of the Slug Curse?

13 Bombarda Maxima
14 Petrificus Totalus
15 Reducto
16 Stupefy
17 Lumos
18 Incendio
19 Fiendfyre
20 Protego Horribilis
21 Protego Diabolica

Most powerful spell. It incinerates anything it touches. It a more powerful version of fiendfyre.
