The Hippogriff Marks The Spot is one of the Hogwarts Legacy treasure hunt side quests in which youβll have to find a treasure chest using the clues in Henriettaβs Map. But they are not the typical pirate treasure maps, where X marks the spot, and youβll have to dig for the treasure.
To get to the treasure, youβll have to solve a series of puzzles and riddles while fighting Dark Wizards. So, to make your life easier, we will explain how to use Henriettaβs Map to find the treasure in Hogwarts Legacy.
The Hippogriff Marks The Spot becomes available to start after you progress the story until you have finished Tomes And Tribulations Main Quest and reached at least Level 13. Even though the side quest requires Level 13 to start, youβll encounter many Dark Wizards between Level 20 and Level 35.
So, I recommend reaching at least Level 20 and switching the difficulty to Story if you are keen to complete the side quest early and to have a chance of surviving against the powerful Dark Wizards youβll encounter. To start The Hippogriff Marks The Spot side quest, go to the Poidsear Coast using the flying broom and reach the Poidsear Castle.
Clear the Poidsear Castle of the Dark Wizard enemies and pick up the rolled parchment from the table inside a tent west of the castle to start the side quest.

Where To Find Henriettaβs Map Treasure (Puzzle Solution)
Henriettaβs Map shows you a secret entrance under a large building in the southernmost part of the Manor Cape Region. It also shows that you must have unlocked the Incendio spell you learned during Professor Hecatβs Assignment 1 and the Glacius spell you learned during Madam Kogawaβs Assignment 1 to solve a Hippogriff puzzle.

Make sure you have learned both spells if you want to complete The Hippogriff Marks The Spot riddle. In the image below, youβll find the exact location of the secret entrance marked on Henriettaβs Map.

Defeat the Dark Wizards in the area, then go down the stairs beneath Merlinβs Trial to find Henriettaβs Hideaway. After you enter Henriettaβs Hideaway, youβll have to solve a short puzzle involving cubes to progress further. On the left side of the room, there is a statue with a brazier in front of it. Cast the spell Incendio to ignite the brazier and reveal a second cube.

Cast the spell Accio youβve learned during Charms ClassΒ Main Quest on the cube and pull it onto the pedestal next to the other cube. Now, cast Incendio on the left cube and Glacius on the right cube to reveal a secret door behind them.

If itβs not working, make sure you have each cube on its corresponding pedestal with the same symbol. Go through the door and defeat all the Ashwinders in the next room. In the middle of the room is a Hippogriff statue surrounded by braziers, similar to the one weβve seen on Henriettaβs Map.
The answer to the riddle is to ignite the braziers and extinguish the others in the exact same order as on the Map. To make things easier, ignite all the braziers with Incendio first, then use the Glacius spell to extinguish the ones we donβt need. Check the image below for the exact order.

After you solve the riddle, a wall behind the statue will open, revealing Harrietaβs chest. Open the treasure chest to receive Treasure-Seekerβs Glove gear appearance, 400 Galleons, and 180 XP.
