Harry Potter may just be the series that never dies. After all these years, fans are still finding magical ways to ensure we never forget our favorite wizards, between makeup lines, virtual reality games, recreations of '90s sitcoms, and uh, a really amazing chart that shows just how often our favorite wizards used their magical ways.

If you're a true Potterhead, there are just some things that you need to know off-hand, like for example, precisely how many spells were used in the entire Harry Potter series, and which of them were more frequently evoked than others. These are just facts that need to be shared. Thankfully, Mashable reports that Skyler Johnson, resident U.S. hero and leader of the free Potter world, did us all a solid by creating a graph that would do just that.

The top five spells used in the series were Accio, Expecto Patronum, Stupefy, Expelliarmus, and Avada Kedavra (dark). They're arranged on a graph that interweaves their order of appearance and frequency of appearance. If nothing else, you now have a little more ammo if anybody wants to test your HP knowledge.

For example: how many fans are going to remember what "Waddiwasi" is, or know that it was the most infrequent spell used in the series? Only the true Potterheads, that's who. Check out the whole graphic here.
