Talk to Arthur Plummly

Just talk to Arthur one floor above Professor Fig’s Classroom. He will give you a paper with three hints.

Find the first landmark from Arthur’s Treasure Map

For the first landmark, just go down the stairs in front of Arthur. Then you will see the rhino skeleton already on the left side, just go near it and you can proceed to the second landmark.

Find the second landmark from Arthur’s Treasure Map

After the first landmark, go to The Astronomy Wing > Transfiguration Courtyard, and go near the statue in the middle of the courtyard.

Find the third landmark from Arthur’s Treasure Map

Follow the quest marker behind the statue from the second landmark and go through the door. The third landmark is just a staircase.

Find the painting from Arthur’s Treasure Map

Go up the staircase (the third landmark) and you will find the painting.

Discover the painting’s secret

Now just use Accio at the top of the painting to reveal a Chest behind the painting and open it.

Return to Arthur Plummly

Now you can return to Arthur in The Astronomy Wing above Professor Fig’s classroom.

This finishes Cache in the Castle Side Quest in Hogwarts Legacy.
