As an avid Genshin Impact player and gaming guide writer, I know first-hand how tricky some of the puzzles in Teyvat can be. The “Look for the Submerged Cave” objective in the Royinja’s Chapter: Linga world quest definitely stumped me at first. But after some exploration and trial-and-error, I uncovered the cave’s sneaky hidden entrance.
In this comprehensive guide, I’ll walk you through how to find that elusive submerged cave entrance step-by-step. I’ll also provide tips to complete the cave’s challenges based on my own experience. So grab your best spears and bows, and let’s dive right into this secret cave together!
Overview of Royinja and the Linga Quest
Before we look for the cave, let’s provide some backstory first. Royinja is an NPC you may remember helping during the Archon quest “Through the Mists.” He is a descendant of the ancient kingdom of Gandharva Ville located in the Golden Apple Archipelago.
After assisting Royinja previously, he invites you to meet him again on Gandharva Ville during the Islands of Midsummer Adventure event. This kicks off the Linga world quest, where Royinja tasks you with finding four hidden ancient murals across the islands.
These four stone Linga murals eventually lead you to search for a hidden submerged cave along Gandharva Ville’s shores. Finding this cave will let you further piece together the history and secrets of the ancient kingdom. So it’s an important quest for fans of Genshin Impact’s lore!
The Tricky Submerged Cave Entrance Location
The navigation point provided during the quest marks a spot offshore from Gandharva Ville where you need to search for the cave. But it doesn’t pinpoint the exact entrance location. Here’s a step-by-step guide to finding it:
1. Head Towards the Yellow Map Marker
Open your map and set a waypoint on the yellow navigation point provided in your quest log. This will mark the general vicinity of the hidden cave.

The yellow map marker points towards the cave‘s location.
2. Look for the Glowing Plant on the Cliffside
From the waypoint, head towards the coastline. You’ll see a cliff face with a ledge you can walk on, and a glowing plant visible on the cliff above.

A glowing plant marks the cliff near the cave entrance.
3. Jump Down and Turn Around
This is the key to revealing the entrance! Do not try entering where the plant is. Instead, jump off the ledge so you’re facing the ocean. Then turn around 180 degrees.
4. Swim Into the Now Visible Cave
After turning around, you’ll spot the opening to a cave in the cliffside. Swim forward into the mouth of the cave to enter.

Swim forward once you spot the cave entrance.
And that’s it! The quest marker will update once you’re inside the cave, prompting you to drain the water. Finding the hidden entrance just takes knowing to look behind you.
Draining the Submerged Cave of Water
Upon entering the cave, your new goal is to “Lower the water level.” Follow the linear cave path, take the first right, and you’ll come across a wall mural with musical note symbols on it.
Interact with the floor panel to begin a rhythm game. Tap the prompted buttons to repeat the tune known as the “Rhythm of Vamadha.” Completing this simple music puzzle will drain all the water from the cave.

Interact with the mural to initiate a music puzzle that drains the cave.
The cave will now be fully accessible. Light the torches along the way to help navigate the dark interior.
There are also treasures and enemies inside, so I recommend bringing an archer or mage like Fischl, Yanfei, or Ningguang. Ranged attacks make dealing with foes like treasure hoarders much easier in the tight cave corridors.
Common Mistakes to Avoid
Here are some pitfalls that can prevent you from finding the submerged cave entrance:
-
Going directly to the map marker – Don’t just aim for the yellow navigation point itself. It marks the general area, not the precise spot.
-
Trying to enter where the plant is – The glowing plant on the cliff only indicates you’re near the cave. Don’t attempt to enter there.
-
Forgetting to turn around – After jumping down, you must turn back towards the cliffside to reveal the entrance.
-
Using melee characters – Ranged party members really excel in the narrow cave. Avoid crowded melee fights here.
Tips and Strats for the Submerged Cave Quest
Here are some tips beyond just finding the entrance to help you fully complete this tricky world quest:
-
Use an archer or mage as your main DPS – Again, ranged attacks make fighting in tight spaces much easier.
-
Light torches to navigate the dark – Illuminate your path to see where you’re going and not get lost.
-
Save your elemental bursts – You’ll need bursts to quickly defeat the cave’s challenging Ruin Grader mini-boss.
-
Craft healing and revival items – The cramped battles can overwhelm your party, so come prepared to keep them alive.
-
Make geo constructs to block enemies – Geo structures like Zhongli’s pillars can obstruct foes in narrow corridors.
-
Equip a shielder like Diona – Strong defensive support also helps survive the cave’s intense battles.
Piecing Together Gandharva Ville’s History
So why is finding this hidden cave so meaningful? Well, it holds clues to the history of the ancient kingdom of Gandharva Ville long before it was destroyed in cataclysmic disasters.
The Linga murals guiding you to the cave, plus engravings within it, all shed light on Gandharva Ville’s culture, faith, and eventual destruction. Solving these puzzles ultimately helps you and Royinja honor his forgotten ancestry.
Other world quests surrounding Royinja, like Songs of the Dragon and Moon, reveal more of this poignant backstory as well. Fans praise these interconnecting questlines for their beautiful music, emotive storytelling, and clues to Teyvat’s past.
