'Mer-Ky' Depths

Need help with the 'Mer-Ky' Depths side quest in Hogwarts Legacy? Follow our guide to find Nerida Roberts, solve the Moth Door puzzle in the Leaky Caves, and claim your reward!

Alright, so you've stumbled upon Nerida Roberts, who's chilling by the Boathouse decking. She's got a bit of a unique situation – she's a 'Liaison to the Merpeople' but, get this, she can't swim! Kind of a pickle, right? She's feeling like the Merpeople aren't getting the respect they deserve, kind of like how Goblins and Centaurs are represented. To smooth things over, the Merpeople left her a gift in an underwater cave, and she needs a brave witch or wizard (that's you!) to go fetch it.

You'll have a few chat options with Nerida. If you tell her “I can help you,” you'll officially kick off the ‘Mer-Ky’ Depths side quest. If you're curious about the bigger picture, you can ask her “Tell me about wizardkind’s relationship with Merpeople” to learn how they're often seen as lesser beings. Want to know what her job entails? Ask “What would a liaison to the Merpeople do?”, and she'll explain her role in sharing knowledge between the two groups. And if you're really fascinated, the dialogue option “What’s so interesting about merpeople?” will send her off on a passionate tangent about her love for them.

Once you've wrapped up your chat, you'll spot a marker out in the middle of the lake. This is your cue – it's the diving point that'll get you into the Leaky Caves. Think of it like finding those secret spots on the world map.

Inside the Leaky Caves, you'll run into a three-Moth door puzzle. Don't sweat it, this one's pretty straightforward. You'll need to use your Luminose spell to zap the Moths and finish the spell when you're right next to the door. For the two Moths that are a bit stuck behind webbing, just hit 'em with a fire spell like Incendio to clear the way. Once that's done, you'll reveal a room containing a stone chest. Inside, you'll find the “Mermish Artefact” – the very thing Nerida needs!

Your last step is to head back to the surface and hand over the Mermish Artefact to Nerida. She'll be able to continue her own quest with it. You'll get to decide whether to give it to her or keep it, but honestly, being a legend and giving it back is probably the way to go. As a reward for completing the ‘Mer-Ky’ Depths side quest, you'll snag the “Mermish Liason Uniform” and a cool 180 XP.
