Talk to Nerida Roberts (NPC) at the dock by the Hogwarts Boathouse to initiate the quest.

Talk to Nerida Roberts

Nerida Roberts will ask you to get him a Mermish Artefact which is required to improve the relationship between Wizardkind and Merpeople.

Find the leaky cave

In order to acquire the Mermish Artefact, a player must swim to the designated location near the Boathouse and then interact with the whirlpool marked on the surface to dive into the leaky cave.

To find and collect the mermish artifact.

There are 3 moth stands in the cave where you emerge in. Burn the spiderweb using the Incendio spell.

Subsequently, use Lumos to move the moths to the moth door. Take all three moths and proceed to the eastern moth door. Follow one moth at a time.

Finally, head inside and open the chest located within the room that has a Mermish Artefact.

Now return to Nerida

Finally, go back to Nerida. Talk to her to complete the quest.
