Roblox‘s Fisch received a huge update called Mariana’s Veil, and it’s got players grinding for all the new stuff. As promised by the devs, there’s a ton to check out, including bestiaries, secret fish, new rods, quests, and even a massive boss fight at the end.
The best part is that Mariana’s Veil is a permanent update, just like Atlantis, so there’s no rush for players to finish everything at once. For those interested, here’s a rundown on all the new content in the Mariana’s Veil update and how to complete it quickly in Fisch.

Fisch: How to Get the Submarine and Enter Mariana’s Veil
Mariana’s Veil is a new underwater region in Roblox’s Fisch that you can only reach by submarine. Here’s how to get one in the game.
How To Complete The Mariana’s Veil Update In Fisch
Here’s a detailed overview on the Mariana’s Veil update and what it brings to the world of Fisch:
New Dr. Glimmerfin Quest
First things first, Dr. Glimmerfin has a new quest for you, and it’s all about building a submarine—the watercraft that will take you deep into Mariana’s Veil. This is one of the first tasks in the update. Players just head to Roslit Bay’s lighthouse area and interact with Dr. Glimmerfin to get started.
Five Bestiaries And Secret Fish
Once you build your submarine and enter Mariana’s Veil, you’ll come across five spots below. As expected, their bestiaries are packed with their native fish, but the twist here is that each location also has a secret fish that triggers a cutscene when caught. Here’s a list of all the cave layers, along with details of the new fish:
All Mariana’s Veil Locations |

Submarine Upgrades And Glimmerfin Suits
Since, at first, you can only access the first layer (Volcanic Vents) of Mariana’s Veil, and the deeper layers are locked because you don’t have the right gear to dive further, and your watercraft can’t handle the pressure, you’ll need to complete a small submarine upgrade quest.
Players will upgrade their watercraft three times, but only in the first three layers. Doing so will also grant you different levels of Glimmerfin Suits, outfits that must be equipped in each area to maintain temperature and warmth.

Puzzles And Challenges
The Mariana’s Veil offers some puzzles for players to solve, similar to Atlantis’ Zeus Trial. However, these are only found in the Calm Zone (the fourth layer), and solving them will unlock the Veil of the Forsaken (the final location). Here’s a quick look at the challenges:
Calm Zone Puzzles |
Solution |
---|---|
1. Obby |
Jump across floating rocks and complete the obstacle course. |
2. Giant Gate |
Place three secret fish (Magma Leviathan, Frozen Leviathan, and Crowned Anglerfish) on their respective podiums. |
3. Scylla Boss Fight |
Move four chess pieces to their correct positions and assemble the crossbow while dodging Scylla’s fireball attacks. |
Scylla Hunts
After upgrading your submarine, solving all the puzzles, and reaching the final part of Mariana’s Veil in Fisch, you’ll find a pond where Scylla Hunts take place. This is a server event announced to all players, but only those with access to this area can participate and catch it.
Exclusive Rods
Last but not least, the Mariana’s Veil update brings five powerful rods to Fisch—some are great for making money, others for EXP, and a few excel at both. However, most of them come with a hefty price tag. Here are all the update-exclusive rods:
Just like before, this update also features premium bundles and boats. Keep an eye out when the boats dock at different islands to grab the available items.
