Fisch has dropped some exciting content with the new update, and at the center of it all lies the new Luminescent Cavern. This place is an extension of the Desolate Deep, a glowing cavern that requires special Keystones to unlock. Each player has a unique combination of what keystones are required to open the cavern. Since these are all scattered across different islands, you will need some assistance. In this guide, we will help you with all the Keystones locations with coordinates, along with the way to enter the Luminescent Cavern in Fisch. So, without further ado, dive right in.
All Keystone Locations in Fisch
Before setting out to gather the keystones, make your way to the back of Sunstone Island to the entrance of the Desolate Deep. Dive right below the Red Buoy with your diving gear and make your way to the right to locate the Mysterious Crack. Here you’ll find three pedestals. So, interact with them to see which three you need to unlock the Luminescent Cavern in Fisch.
Once you know the required keystones, head over to the specific locations and interact with them to grab them. That said, here are the exact locations for every keystone to unlock the Luminescent Cavern in Fisch:
- Cliff Keystone: Located on the Castaway Cliffs at coordinates 473, 230, -2159. Find it in a small gap beside the ledge that leads to the second level of the island.
- Mushroom Keystone: Located on the Mushgrove Islands at coordinates 2666, 130, -717. Find it on top of the boat near the Alligator abundance area.
- Fossil Keystone: Located on the Ancient Isles at coordinates 6065, 225.5, 259.5. Look for it on the heap of woods, lifted by the cranes near the merchant.
- Snowflake Keystone: Located on the Snowburrow at coordinates 2788, 153.5, 2603. Search for it inside the cave beside the pine tree. Snowburrow only opens after players interact with three cracks in the Snowcap Cave.
- Volcano Keystone: Located on the Roslit Volcano at coordinates -1970, 175.4, 268. Check the middle stone inside the volcano.

How to Get to Luminescent Cavern in Fisch
After gathering all three keystones required by the pedestals, you’re now ready to unlock the Luminescent Cavern. So, head back to the Red Buoy, equip your diving gear, flippers, and dive deep into the sea. Here’s a step-by-step process to unlock the new area:
- From the Red Buoy, make your way underneath and head straight to the warning sign.
- Take the right and head straight till you find a glowing blue coral.
- Now take a right turn again, and you’ll locate the Diver NPC.
- Here, you will find the three pedestals, placed on the ground.
- Equip the keystones and place them on the designated pedestals by pressing the ‘E‘ key.
- Do note that if you try to place a non-matching keystone, an error message will appear stating the right one required.
Once all three are in place, the mysterious crack in the wall will open up. Swim through the gap, and you will gain access to the Luminescent Cavern. However, before you can fish, you must cross the Mysterious River. After you cross it, you can fish and catch all the new creatures to unlock the next cavern introduced in the update.
That completes the guide to unlocking the Luminescent Cavern in Fisch and where to find all Keystones. So, what new fish have you caught in the new bestiary? Tell us in the comments below.
