Seriously, who hasn't watched them? Even if you're not that interested in the genre you have to just watch 'em to say you have and see what the fuss is about.
I re-tooled the Harry role for the recent game, so as he'd learn new spells every other day. Expeilliarmus - blocks Lumos - watches self Expecto Patronum - docs Sectumsempra - vig Sadly the game progressed quicker than I'd intended and AVA died with only 2 spells.
