Players can take on the Cache in the Castle quest from Arthur Plummly in Hogwarts Legacy, but they must follow Arthur’s map to reap the rewards. The map illustrates four landmarks within Hogwarts and will eventually lead to an undisclosed hidden treasure. Beginning in the Astronomy Wing, treasure seekers must locate each of the four landmarks on Arthur’s map and use the right spell to access the treasure. Upon completing the quest, players get to keep the treasure they have found and gain XP to level up.
