|---|---|---|
 Lumos | Incendio | Confringo |
You can use either Incendio or Confringo
- Speak to Nerida at Boat Hut
- Find the Leaky Caves
- Find the Mermish Artefact
- Report to Nerida
The Boat Hut can be headed from the Great Hall. Speak to Nerida and learn that she will want you to get the "Gift from the Merpeople".
The Leaky Caves is really close to the Nerida location. Use the guide and swim over to it.
Inside the cave, there are three locations to call the moths with "Lumos". There are Spider Webs on 2 of the locations so you will need to burn then with Fire Spells. When you fill the 3 moths then the door will open and a treasure chest will be inside.
You will have options when you report to Nerida. Both will give you rewards, but if you choose "I've decided to keep the gift" → "I don't think you've earned it" then you will be able to receive the Mermish Artefacts as well.
