If you could have one spell from 'Harry Potter' what would it be? Watch
Or, as above, accio!
Expelliarmus has to be the most overrated spell. I know Harry raves on about how amazing it is but if it was that good Dumbledore and Voldemort would try and use it on each other. It's pretty much the first spell everyone learns and Harry uses it constantly, boring spell.
Turn this stupid, fat rat yellow!
