- Travel east from Moosewood, and dive underwater near the group of boats to find Tidefall in Fisch.
- Use the water bubble or the advanced diving gear and the tidebreaker to survive the pressure.
- Complete the Rescue Diver quest to unlock the Abyssal Tonic and explore the area safely.
Tidefall is out in Fisch and has turned out to be one of the most mysterious locations you can explore. While unlocking it feels like a true deep-sea adventure, it won’t be an easy task at all. This location is hidden far below the ocean that even a submarine can’t reach. Not because it is not strong enough, but rather, there won’t be enough room for that. So, if this interests you even a bit, check this guide to find out how to unlock the Tidefall in Fisch and what the basic materials are that can help unlock this area.
How to Enter Tidefall in Fisch
Tidefall is not a specific island but rather a point on the Fisch map, from where you can dive down to reach the new bestiaries, rods, and spears. So, if you have begun your journey from Moosewood, take your best boat or a submarine and head east towards the Ancient Isles.
The Tidefall area is located in this direction, and it won’t be long before you notice the group of boats at these coordinates: 3224, 130, 847. Use the Fisch GPS to reach this location. Now, you can follow the steps below.
- You can now use the submarine to head down and enter the opening below.
- But soon, the submarine will be restricted from heading further down, and you need to get out of that and swim below on your own.


- Dive down and take the path in front of the capsized grey Submarine below to find a small crevice.
- Move through this narrow opening, and you will soon enter the new area called the Tidefall.
- While diving down, remember to equip the Advanced Diving Gear, Super Flippers, and even carry the Tidebreaker so that you make it without the heavy pressure killing you instantly.
- Otherwise, unlike me, if you have unlocked the Water Bubble, equip it and head down, instead of following the above step.
- Tidebreaker goes perfectly with the Water Bubble and will help you reach the entrance before the purple meter even touches 80.

How to Complete Rescue Diver Quest in Fisch and Unlock Abyssal Tonic
Before fully exploring Tidefall in Fisch, completing the Rescue Diver quest is highly recommended as it unlocks a vital item for this deep-sea adventure. Once you reach the Tidefall area above the water surface, you will notice a huge red boat with a couple of diver NPCs on it.
Get on the boat and interact with them to initiate the recovery quest. They will inform you about a diver who went missing during an earlier expedition. Now, head back down the same underwater path you used to reach Tidefall.


But near the entrance, right in front of the capsized submarine, you will find the lost diver. Interact with him by pressing and holding the ‘E‘ key to carry him on your back. From here, you must swim all the way back to the surface.
This part is time-sensitive due to the high water pressure. Make sure to use the Tidebreaker tool to move faster and reach the surface before your health runs out. Once you return to the red boat and deliver the diver, you will unlock the Abyssal Tonic.

Although the Abyssal tonic exists in the Tidefall area, it remains locked until this quest is completed. After unlocking it, you can purchase the tonic for 500C$. Consuming this tonic completely negates the underwater pressure damage, allowing you to freely travel in and out of the Tidefall crevice without worrying about dying.
So that is how you can enter Tidefall easily in Fisch and explore all the bestiaries down there. Have you explored all the regions in this location yet? Tell us in the comments below.
The Tidefall is located between Moosewood and the Ancient Isles in Fisch.
A submarine is not necessarily required to unlock the Tidefall, but using it to go a bit deeper can help players negate the water pressure damage for a slight bit.
The Abyssal Tonic removes water pressure damage, making the deep dives to Tidefall much safer and faster.
