Dumbledore's Office and Quidditch | Walkthrough HP and the HB Prince Guide
Last update: 11 May 2016
After the cutscene ends, go to the Entrance Courtyard [1] and into the corridor on the right. Approach the stone monument in the corner [2]. If you have problems with finding this location, you can press N and ask Nick for help.
Inside you will have a conversation with Dumbledore [1]. Once it ends, you will be transported to the corridor [2].
Follow Katie. After a while you will get to the top of the Clock tower. Turn left [1], head to the stairs and go to the very bottom [2].
Try to leave to Clock tower through the wide passage. The gate will be locked in the last moment [1]. Now you have to assemble a key [2] with the Reparo spell. In order to do this, hold down the left mouse button and move the mouse clockwise.
Once you're done, Katie will raise the gate. Run through the Clock Tower Courtyard [1] and head to the wooden bridge [2] in front of you.
After you cross the bridge, you'll arrive at the vestibule [1] leading to the Stone Circle. Once you leave the building, you will be attacker [2] by one of Malfoy's thugs. Knock him down using Expelliarmus and finish with Stupefy.
After the duel, go down the road on the right [1] (looking from the vestibule exit). After getting to the top, follow Katie and she'll show you the way to the cave [2].
Go inside and forward all the time [1]. The cave will lead you to a wall [2], surrounding this part of the castle. Run across it.
Enter the tower ahead of you and go down the stairs [1]. Once you exit the building, head to the Quidditch Gate on the left [2].
Once the scene is over, training will begin. Your task, as always, is to fly through the stars appearing in the air [1]. In the later part, dummies with pumpkin heads will also start to appear [2]. Try to fly into them, as you will get additional time for that. After the trainings over, you will find yourself back in the Quidditch Gate.
