Slughorn's Staircase

Horace Slughorn's Staircase is one of the largest staircases in Hogwarts Castle. It extends from the Dungeons to the Seventh Floor. It has another exit on the sixth floor, near Horace Slughorn's office. The layout of the staircase is very similar to the Divination and Defence Against the Dark Arts Staircases, but with a deteriorated side at the bottom.

Professor Slughorn used this staircase when going to his classroom in the Dungeons, whereas Luna Lovegood used it for the first time while going to the Slug Club Christmas party with Harry Potter.

1996–1997 school year
Horace Slughorn used to go down this staircase in his way to the Potions Classroom. The students used the staircase to go from the dungeons to the sixth and seventh floors of the castle. Besides that, Harry Potter and Luna Lovegood used it in their way to Slug Club Christmas party.

Behind the scenes

 * It only appears in the video game adaptation of Harry Potter and the Half-Blood Prince and seems a replacement of the Divination Staircase, as it does not make an appearance.
 * The name of the staircase is probably because it connects Slughorn's office to Slughorn's classroom. It is only given in the Nintendo DS version of the game.
