cache in the castle hogwarts legacy Complete Quest Walkthrough and Collectibles

Exploring the massive environments in Hogwarts Legacy opens up a wide variety of secrets and optional assignments for curious spellcasters. One early side mission that many players stumble upon is Cache in the Castle, which tasks you with deciphering a sketchy treasure map given by a fellow student. Completing this scavenger hunt allows you to practice your observation skills while earning unique cosmetic items for your collection.
Starting the Quest in the Astronomy Wing
To initiate this journey, you need to speak with Arthur Plummly, a student located near the Defense Against the Dark Arts classroom. He will hand you a unique piece of parchment containing three distinct illustrated hints. Finding these landmarks in the proper sequence is essential to revealing the hidden cache.
The first destination on the map requires you to head down toward the Transfiguration Courtyard. Look closely for a large rhinoceros skeleton display sitting inside a glass case nearby. Once you stand close to this landmark, your quest tracker will update to guide you toward the next location.
Tracking the Second and Third Landmarks
After observing the skeleton, follow the map instructions toward a prominent fountain featuring a stone dragon in the center. This courtyard area serves as a central hub connecting various wings of the magic academy. Approaching the fountain satisfies the second clue, pushing you closer to the final puzzle area.
From the dragon fountain, look for a nearby double door that leads into a large stairwell going upward. Follow these stairs until you spot an intricate oil painting depicting a snow-covered house surrounded by trees. This artwork holds the final mechanical secret required to complete the scavenger hunt.
Solving the Painting Puzzle and Claiming Rewards
To interact with the painting properly, you must cast the Accio summoning charm on the decorative frame handle at the top. This action triggers a hidden doorway mechanism behind the wall to open up smoothly. Inside the small alcove, you will discover a vintage chest containing your hard-earned treasure.
Opening this container rewards you with the Authentic Historians Uniform, a highly sought-after cosmetic appearance item. Return to Arthur Plummly near the starting area to share your findings and officially close the assignment. Taking the time to finish these small activities provides excellent world context and enhances your character progression early in the game.
