How to find Mermish Artefact in Hogwarts Legacy

To find the Mermish Artefact, you will have to find Nerida Roberts. She will be outside Hogwarts School. Follow the yellow marker and reach her at the Boathouse Area. Nerida Roberts is a Slytherin Student studying at Hogwarts, and she will require you to get her the Mermish Artefact that her mermaid friends have left for her in a cave under the water. She also added that she would need my help to do so because she doesn’t know how to swim.

As you agreed to help her, you will be in control, and the Mer-ky Depths mission will start. All you need to do is jump into the water and swim towards the white marker. As soon as you reach there, you will find a whirlpool that prompts you to press the F button to dive in.

After diving in, the game will load, and you will be back inside the cave Nerdia was talking about. Get out of the water and walk straight until you reach a yellow door with three butterflies. So to solve this puzzle, you need to bring in three illuminated butterflies near that door so that they can automatically align and fit into it.

You will find the first butterfly directly opposite the door. You need to go around and reach near it. It is straightforward to spot so you won’t have any issues with it. Go near it and use your Lumos Spell to attract that butterfly, bring it back to the door, and press the left button to fit it into one of the spots automatically.

The second one is just on the right side as you come out of that door. It will have cobwebs in front of it, so use your Confringo Spell to burn the webs and then use the Lumos spell to attract the butterfly and bring it back to the door and press the left button to fit it.


The third one is the same process. As you leave the door area, go to the left and use the Confringo spell to burn the cobwebs and attract the butterfly with your Lumos Spell. Bring those butterflies near the door, and the chamber opens for you.
