Voting rules: Choose the spell you think is the most difficult!
This is a community-based ranking of the most difficult spell in Harry Potter. We do our best to provide fair voting, but it is not intended to be exhaustive. So if you notice something or spell is missing, feel free to help improve the ranking!
A participant may cast an up or down vote for each spell once every 24 hours. The rank of each spell is then calculated from the weighted sum of all up and down votes.
