There are a total of eleven treasure vaults in the Marunweem Lake region of Hogwarts Legacy. To solve them, you will need to have the spells Bombarda, Glacius, Windgardium Levioso, and Depulso.

1. Boarded Up Treasure Vault

   Approach the vault, defeat the goblins, and fly directly into it with your broom. Follow the hall to find the treasure chest.

2. Mountain Base Treasure Vault

   Follow the road past the Coastal Mine Floo Flame. Use Revelio to highlight the levers, then use Accio on them to open the treasure chest door.

3. Central Mountain Treasure Vault

   Mark this vault on your map and land your broom nearby. Defeat the goblins, then use Depulso on the device until rocks move. Climb the rocks to reach the treasure chest.

4. Tower Tunnel Treasure Vault

   After the central mountain vault, follow the path to the Tower Tunnel Floo Flame. The vault entrance is across from it. Follow the hallway inside to find the treasure chest.

5. Underwater Treasure Vault

   Locate the swirling dive spot in Marunweem Lake. Dive in and swim until you see an Accio device. Use Accio on it to open the door on the ledge, then head inside for the treasure chest.

6. Central Treasure Vault

   Located next to the Marunweem Lake Floo Flame. Simply enter the vault and follow the hallway to the treasure chest.

7. Wizard Chess Treasure Vault

   Adjacent to the Marunweem Lake Floo Flame. Obtain a cube from a nearby poacher camp, open the cage with Alohomora III, and drag the cube to the pedestal. Cast Glacius on the cube. Inside, use Revelio to find the movable pot and drag it onto the chessboard with Accio. Place it across from the mage and use a transformation spell to turn it into a chess piece. The chess piece will attack, revealing the treasure chest.

8. Cliffside Treasure Vault Near The Island Ruins
