What do we need to reach the LUMINESCENT CAVERN In Fisch?

List of all the Keystones you need:

• Volcano Keystone

• Turtle Keystone

• Squid Keystone

• Lightning Keystone

• Sun Keystone

• Cliff Keystone

• Mushroom Keystone

Where to get the Volcano Keystone:

On the path to the LUMINESCENT CAVERN In Fisch, we start with the Volcano Keystone. For this, you need to go to the southern part of the Volcano region.

Exact Location:

• The keystone is in plain sight near the volcanic ground.

• It appears as a distinct stone marker.

• Simply interact with it to add it to your collection.

The Volcano Keystone is one of the easiest of the 9, as you just have to pick it up without any special task.

Getting the Turtle Keystone:

To get this Keystone, you need to find your way through the cave inside Turtle Island.

Step-by-step instructions:

• Travel to Turtle Island.

• Find the cave entrance on the island.

• Enter the cave and go through it.

• Move to the right side of the cave.

• The Turtle Keystone (green in color) should be visible in this area.

This cave isn't very complex, but you need to pay attention and check the area carefully.

Getting the Squid Keystone to reach the LUMINESCENT CAVERN In Fisch:

You can get the Squid Keystone in Forsaken Shores.

Navigation Path:

• Travel to Forsaken Shores.

• Enter the main building.

• Go up through the floors of the building.

• Keep going up until you reach the upper sections.

• The Squid Keystone should be located in the upper part of this building.

Most of your time finding this Keystone will be spent searching the floors of this building, so look carefully to avoid checking the wrong floors.

Location of the Lightning Keystone:

To get the Lightning Keystone, you need to go to the Grand Reef area and search all the small islands around it.

Finding the Keystone:

• Head to the Grand Reef area.

• Check the small islands in this region.

• Look for a yellow-colored keystone.

• The Lightning Keystone should be clearly visible on one of these islands.

The best way is to search the islands around the Grand Reef one by one until you find the Keystone.

Location of the Sun Keystone:

You can find the Sun Keystone in Moosewood, inside the main building.

Location Details:

• Go to Moosewood.

• Enter the Moosewood Inn (the main building).

• Search the inside carefully.

• You can find the Sun Keystone inside this building.

Getting this requirement for the LUMINESCENT CAVERN In Fisch isn't hard; you just have to search inside the building.

Where to find the Cliff Keystone?

Get ready for some climbing. The way to get the Cliff Keystone is by climbing the Snowcap Cliffs, and you need to find this stone halfway up.

Climbing Path:

• Travel to Snowcap Cliffs.

• Start climbing the cliff.

• The keystone is located halfway up the cliffs.

• Look for it on the rock surfaces on your way up.

Choose your climbing path carefully to avoid falling and having to climb the mountain all over again.

Location of the Mushroom Keystone

To get the Mushroom Keystone, you need to take a boat to Mushgrove Swamp.

Access Instructions:

• Take a boat to Mushgrove Swamp.

• Explore the swamp area.

• The Mushroom Keystone should be visible in the swamp ground.

• Pick it up from its resting place.

Check the entire swamp area. It's a bit messy, so you need to look very carefully so you don't walk right past it.

The Hidden Snowcap Keystone Location

To get the Snowcap Keystone, you need to access a hidden area within Snowcap and solve a puzzle.

Opening the Hidden Area:

• Go to Snowcap.

• Find three cracks in the ice/ground.

• Quickly interact with all three cracks.

• If you're fast enough, a hidden area will open.

• The Snowcap Keystone is revealed inside this area, placed near a tree.

Speed is very important for solving this puzzle. You need to move quickly between all three Cracks within the time limit to solve the puzzle and access the Snowcap Keystone.

Location of the Fossil Keystone:

The final piece of the 9 Keystones you need to reach the LUMINESCENT CAVERN In Fisch is the Fossil Keystone, which you can find on Ancient Isle.

Collection Path:

• Travel to Ancient Isle.

• Head towards the main building/ruins.

• Move through the ancient architecture.

• The Fossil Keystone is located in the ruins area.

How to open the entrance to Luminescent Cavern?

Now that you have all 9 keystones, you need to go to the keystone area and find the entrance.

The Opening Process:

• Go to Desolate Deep.

• Descend into the darker depths.

• Find the door mechanism with the keystone slots.

• Place the keystones in their assigned slots (it shows which keystone goes where).

• When all keystones are placed, the door opens.

A note for this part: the area is completely dark, so you need a lamp or filter to be able to see.

What awaits us inside the Luminescent Cavern?

Now that you've managed to get inside the Luminescent Cavern area after the long journey of getting nine keystones, you can start fishing there and hunt for various unique fish that can really level up your game. You can also find very powerful fishing rods in this area, including The Evil Pitchfork, Luminescent Oath, Ruinous Oath, and more.

An important note about fishing here is that you cannot find the fish from this place anywhere else in Fisch. This is what makes the Luminescent Cavern so unique in the game Fisch and increases the importance of being able to access it.
