Cache in the Castle – Hogwarts Legacy Quest

Cache in the Castle is an optional quest in Hogwarts Legacy. You will be given a treasure map with hints to something hidden within Hogwarts. But what is the secret treasure? In this guide, we’ll help you follow all of the clues and find out.

  • Quest Type: Side Quest
  • Location: Charms Classroom Hallway, Astronomy Tower, Hogwarts Castle (map)
  • Requirements
  • Rewards
    • 180 XP
    • Authentic Historian’s Uniform

To begin the quest, you need to talk to Arthur Plummy. Go to the Charms Classroom Floo Flame, and he will be just down the stairs and to your left. Talking to him (with playstation square button/button xbox x v2) will initiate Cache in the Castle, and he will request that you join his adventure — he found two maps leading to hidden treasures within Hogwarts, and would like for you to find one of them.

After accepting the quest, you will get a look at the treasure map. It will show you sketches of three landmarks within Hogwarts, as well as the symbol for Accio. The first landmark to find will be the rhinoceros on the top right of the map — note that the quest will not make a path to any of the landmarks on your minimap, but will still show markers.

Head down the stairs near where Arthur is, and go down three floors. From here, go down the stairs in the central area, and it will lead you to the landmark. Once you get close enough to the skeleton, you will be prompted to head to the second clue.

The easiest of the landmarks, you now need to find the fountain. From the rhinoceros, head down the stairs and outside to be in the Transfiguration Courtyard. The fountain will be in the center of the Courtyard.

To find the final landmark, run behind the fountain and into the North Hall. Once inside, go forward, then head up the stairs until you see a portrait (1). This is where the treasure is hidden. In order to find it, you will need to cast Accio on the portrait (2). Casting it will reveal a doorway hiding the treasure — open it to find the Authentic Historian’s Uniform (3).

Once you grabbed the robe, report back to Arthur — he will still be near the Charms Classroom, but now after using the Floo Flame to get here, turn around and he will be to your right.
