Preparation
- Ensure you have progressed through the primary storyline up to the Moontide Sea chapter.
- Head to the island positioned north of the Curtain-Form Blackbody Containment Lab to locate the timid Kuuhenki, which starts the quest.
- Eliminate the nearby sphere-shaped adversary, then track the creature to the lab’s entryway.
Phase 1: Starting the Beneath the Lunar Sea Quest
Kick off the journey by locating the frightened Kuuhenki north of the laboratory. After neutralizing the roaming sphere enemy, follow the Kuuhenki to the facility’s front door to officially trigger the Beneath the Lunar Sea mission.
Phase 2: Navigating the Interior
Once you have gained entry, follow these instructions to progress:
- Direct the Ancient Moon Pearl toward the wall-mounted Pearl Power Station.
- Pass through the newly opened portal and descend toward the Moon Energy Pearls.
- Gather Archaeolume Energy and glide across to the northern platform.
- From the central doorway, head left and move behind the damaged wall.
- Clear out the hostiles to liberate the jellyfish.
- Collect more energy and fire Ripples at the Back-Up Power Generator.
- Gather additional Archaeolume Energy and aim it toward the stone stack located beside the jellyfish to trigger the elevator mechanism.
- Retrieve your reward from the Material Storage Chest to deploy the Moon Pearl Launcher.
How to utilize the launcher:
- Pick up Archaeolume Energy, step onto the launcher, and initiate a jump.
- Shoot Ripples at the Archaeolume Energy Barrier on the ceiling above the device to create an opening.
- Wait for the Ancient Moon Pearls to descend.
- Place a pearl onto the launcher and activate it to propel the pearl toward the Power Station by the entrance.
- Follow the item and slot it into the empty Power Station to complete the circuit.
Phase 3: Initializing the Lab
With the pearl secured, the main door will open, granting access to the Containment Lab tree. Interact with the Terminal to fully activate the Moontide Sea exploration system, successfully finishing the quest.
