This is a supercut edited by Davide Rapp of every different spell performed in the Harry Potter movies, in alphabetical order by spell name. I thought it was every single instance a spell was cast too, although now I'm not sure because Snape's Expecto Patronum from the 'After All This Time? Always' scene wasn't included. I feel like that would have been a meaningful one to include. Also, you never realize just how weird Expecto Patronum really sounds until you hear Harry Potter scream it like he means it ten times in a row.
Keep going for the video.
Thanks to Ippo, who tried to cast an embarrassment spell on me via email but it didn't work I just pooped my pants mommy. Dammit.
