The LEGO Dark Arts Classroom set based on Harry Potter and the Goblet of Fire has a magical deal as part of Amazon's Black Friday sales.

The LEGO Harry Potter Hogwarts Moment: Defence Class spellbook kit offers 257 pieces to build Mad-Eye Moody's classroom from The Goblet of Fire. It opens up to a backdrop for the classroom with pieces to put together the archways, desks and other features associated with the room as seen in the films. Although the LEGO set usually sells for $29.99 USD, Amazon's Black Friday deal cuts the price by 30% to $20.99 USD.

Besides the classroom itself, the set also includes minifigs for Mad-Eye Moody, Hermione Granger and Neville Longbottom. Moody's head turns, and his wig comes off to reveal Barty Crouch Jr., and a trunk opens up to reveal the real Mad-Eye locked away inside. In the books and films, the famed dark wizard hunter survived his imprisonment by Crouch Jr. and went on to help the Order of the Phoenix and Harry Potter in the mission to defeat Lord Voldemort.

The LEGO Harry Potter Hogwarts Moment: Defence Class spellbook kit is available now at a discounted price as part of Amazon's Black Friday deals for one day only on Nov. 25.
