The Daedalian Keys is a Side Quest you can complete in Hogwarts Castle. This walkthrough will guide you through all objectives of The Daedalian Keys side quest and all the locations of other Daedalian Keys. There are a total of 16 Daedalian Keys
How to start the Daedalian Key quest
To begin this quest of hunting down the keys, you will need to head outside in the Transfiguration Courtyard and speak to a student named Nellie Oggspire. She will tell you about winged keys flying all around the area, as well as the location of the first one to help get you started. Once you find a key, start following it to a special cabinet where you can start a mini-game to open the cabinet.
Find the Daedalian key in the Astronomy Tower
Fast travel to the Astronomy Tower Floo Flame and then go up the stairs and you will find the first Daedalian key.
Find the Daedalian key’s cabinet
As you approach the Daedalian key it will fly off. Continue to chase the key downstairs into a room near the Fast Travel Floo Flames. In this room, you will find a cabinet.
Open the Daedalian lock
To open the lock the objective should be to “slap” the key as it flies directly over the keyhole of the cabinet. Once you insert the key into the keyhole, the cabinet will open and give you a House Token.
Return to Nellie with the token
Pick the house token and head back to Nellie in The Astronomy Wing -> Transfiguration Courtyard and report what you found. She will then explain that these tokens may be used to open the chest that is linked to your home. When you put the token in your chest, you’ll be informed that you’ll have to find 15 other ones to open the chest.
Find the remaining house tokens that are around Hogwarts
The location of other Daedalian keys is given below.
