Most of the spells learned in Hogwarts are a simple flow of:
- Choose your spell
- Point your wand
- Say the words
- Magic happens
But there are other spells that specify the need to do more than that.
- For Expecto Patronum, one must think about a happy memory, and even if that might sound an easy task, it is still described as one of the hardest spells, one that even grown wizards are unable to perform.
- For Avada Kedavra and Crucio, one must have malicious intentions and want to hurt one's victim.
What other spells require more than just words?
