Need help with the 'Thetis, Medicinal Merperson' side quest in Ni no Kuni II: Revenant Kingdom? We'll guide you to Tidewash Cave and back to Hydropolis.
Hey there! Ready to help out another citizen in Ni no Kuni II? This time, we're looking for Thetis, a merperson doctor who's cooking up a special formula. She's got most of the ingredients, but needs a bit of 'deep seawater' from Tidewash Cave. Let's go grab it for her!
Walkthrough
- 1First things first, you'll need to get to Tidewash Cave. It's located northwest of Capstan. The tricky part is that you'll need to cross a rift. The closest spot to do this is southwest of Hydropolis.
- 2Once you've crossed the rift, follow it west, and then head north when you reach land. Keep an eye out for the cave; it's tucked away in a small inlet and can be a bit hard to spot because the sky is usually dark there.
- 3Before you go exploring inside, make sure to activate the Trip Door at the top of the island. This will make your return trip much easier!
- 4Head straight south from the entrance. You'll pass a group of enemies and find a chest containing Determined Rakish Boots. Grab those if you like!
- 5Continue west until you find an area with a Dreamer's Door. This is where you'll find what you're looking for. Look for a blue sparkle on the ground on the southern side of this area. That's your jar of Deep Seawater!
- 6Once you've got the Deep Seawater, head back to Hydropolis and find Thetis. Hand over the ingredient, and you'll complete the quest!
