Yes, that’s right; dueling. While the app will allow you to challenge an AI opponent, whipping your friend in a digital duel is undoubtedly better, and I can’t wait to test this one out. Fledgling wizards can currently learn up to 14 spells, and the examples given are old favorites: Stupefy!, Expecto Patronum!, Expelliarmus!, and so on. Spells are unleashed with hand gestures and sent between devices. I can’t think of a better platform for a handheld duel, especially given the iPhone’s accelerometer.

Rounding out the offering are a slew of appreciated extras: Facebook Connect, player stats pages, House rankings, and Hogwarts-wide leaderboards. Warner Bros. is obviously attempting to foster some competitive spirit between friends.

It’s worth noting that Harry Potter: Spells isn’t targeted at the 99-cent crowd; the app is selling for $4.99. We’ll have a review up in a few days with our recommendation, but for now, more information can be found at http://harrypotterspellsapp.com/.
