There are five golden knights to shoot. The first is right in front of you as you begin the level. There are two in the next corridor, and two in the following room.

House Crest 2 (01:19):
Once you’re in the large puzzle room with the opening in the middle, solve the puzzle and before you exit the room, destroy the dark wizard boulder that fell off the plinth. The crest is inside.

House Crest 3 (01:25):
Once outside, head up to the level where Filch is patrolling and you’ll see that one of the windows has been boarded up. Use a dark wizard to remove the boards and grab the crest.
