Where To Find Prisonkeep Island

As soon as you unlock Brunnelsumpf, a swampy region of Hinterberg, you can make your way there to encounter its dungeons. The entire region is surrounded by water, but one dungeon is accessible: Prisonkeep Island. Once you get your magic at the Skill Shrine from the area, follow the trail to Prisonkeep Island.

You'll need to place a giant cube in the swamp so you can cross over and reach the portal. Once there, you'll unlock a fast travel point and be able to enter with ease.

Prisonkeep Island Puzzles

Prisonkeep Island is a big dungeon with plenty of puzzles and battles. Many of them require you to pay attention to your surroundings and get creative.

Fish Puzzles

Once you enter the dungeon, you're under the sea. Use your cube to reach ledges that are just a bit out of reach and climb along the reefs to reach the ruined prison.

Send a Plasma Ball towards the blue jellyfish, then stop it once it reaches its target. This raises the bridge so you can cross safely. Enter the prison and fight off the monsters that appear. Take the door on the left once the monsters are defeated.

To escape this chamber, you'll need to send a Plasma Ball into the open fish mouth on the wall. The Plasma Ball will travel through the tube and activate the jellyfish on the other side. Stop it on the jellyfish so you can run through the open gate.

Continue through the dungeon until you reach an open courtyard with two of the fish pipes. Use a cube to climb up on the platform with the button and interact with it. This turns the fish pipe along the wall, swapping directions.

Send a Plasma Ball towards the fish pipe on the ground, then wait until it passes through the second pipe. Press the button to change the second pipe's direction so that the Plasma Ball is launched into the open gate. It will power the ladder so that it drops, allowing you to move forward.

Progress to the next area where you'll have to work with a similar puzzle. Stand on the clam-shaped pressure plate to open the gate, then launch a Plasma Ball at the wall. It should bounce off and travel through the fish pipe.

Climb the ladder that drops and fight off the monsters you encounter inside the open area. You're well on your way to the next portion of the dungeon.

Cube Puzzles

Continue through the dungeon until you reach a dead end. There's a button on a wooden platform that looks like it will open the locked gate. Interact with it and you'll drop through the floor, trapped underground.

Never fear! Line up your cube and place it under the gate. It will force the gate to rise so you can escape and continue dungeon delving.

Back in the courtyard, use the cube to climb up onto the stone platform and interact with the button to flip the wooden box. Kick the ladder down and place a new cube underneath the pressure plate. This will keep the door open so you can move to the next area.

The next puzzle will require you to line up the jellyfish on the rotating handles. The two jellyfish on the ground control the respective handles. Activate one at a time with your Plasma Ball until the two tips are close enough to hit with one Plasma Ball.

In the following chamber, you'll have to get creative. Use the cube to climb onto the nearest platform, then place the cube inside the fence so you can climb over it and reach the other side. From there, carefully place the cube on the next platform and climb it.

Leap across to the highest platform, then place a new cube on it. Send a Plasma Ball into the jellyfish on the wall, then hurry through the now open gate to the next area.

Your next challenge is to cross a pond of toxic water while lasers fire at you. Place a cube on the raft to protect you, activate the raft, and carefully move around the cube as the raft drifts down the water.

Once the raft reaches the other side, hop off and place a new cube in the fence on the left. Leap over and continue along to the final puzzle in the Prisonkeep Island dungeon.

Final Puzzle

The final puzzle will take some preparation. You'll need to send a Plasma Ball into the jellyfish to rotate the platform. Make your way across, then place a cube on the suspended bridge.

Use your Plasma Ball to rotate the platform across from you to reach another button in the ruins. The space across from you has a button that will raise the suspended platform, pushing the slime cube into a pressure plate on the ceiling. This opens the gate at the front of the room.

Now all you need is to get back there. Hop back on the rotating platform and reach the center platform. Pressing the button here will move that platform so you can circle back around to the front of the room. Head along the path and pass through the gate, then ascend the ladder to the final area.

The last area in the dungeon will see you face several waves of monsters. Use your magic to hold them in place as a form of crowd control, defeating them all in a much more efficient manner.

Once they're dealt with, collect your Prisonkeep Island stamp and exit the dungeon to wrap up your day in Hinterberg.
