gain 150 points. The Quidditch players wear gloves, leg pads, padded head guards, and occasionally goggles. Self-Shuffling Playing Cards In Chamber of Secrets, a pack of Self-Shuffling Cards is mentioned as one of the various objects littering the floor of Ron's room in the Burrow. Wizard's Chess Wizard's Chess is played with pieces and a board identical to Chess. The rules are also unchanged. The pieces are magically animated, and they violently attack each other when performing a capture, by knocking the captured piece out and dragging it off the board. The players order the pieces to move using algebraic chess notation. Ron has a wizard's chess set left to him by his grandfather, and Harry first plays with pieces borrowed from Seamus Finnigan, which kept shouting him advice because they did not trust him.

In the films, the chess pieces are depicted using replicas of Lewis Chessmen.

If all of someone's Horcruxes are destroyed, then the soul's only anchor in the material world would be the body, the destruction of which would then cause final death. The creation of Horcruxes is considered the darkest of all magic. This method was chosen by Voldemort to attain immortality. The concept is introduced in Harry Potter and the Half-Blood Prince. J. K. Rowling uses Horace Slughorn's expository dialogue to reveal that the creation of a Horcrux requires one to commit a murder, which, as the supreme act of evil, "rips the soul apart". After the murder, a spell is cast to infuse part of the ripped soul into an object, which then becomes
