@swiff I think most people could beat Harry Potter characters in a wizard duel. All you need is to cast one of the following spells;
1: Sneakus-Attackus-With-A-Clubicus
2: Pistolus-Shooticus
3: A forbidden potion brewed from delivering a righteous Right hook into the nose of your duelling opponent, becuase ain't nobody casting expelliarmus when their nose is currently expelliarmusing a whole buncha red stuff from itself
4: grenade.
