How to Get to Mariana's Veil in Roblox Fisch (Submarine Quest Guide)

Skip To...

Mariana’s Veil is, in a way, a lot like the Northern Expedition in Roblox FIsch, except it’s, you know, lava. And what I mean by that is that it borrows similar mechanics, such as the temperature gauge. When you’re inside Mariana’s Veil, your temperature will gradually rise, so you can’t spend a lot of time there. You have to be quick with your catches and maybe grab some upgrades along the way.

How to Get the Submarine and Enter Mariana’s Veil

Yes, you read that right. You’ll need the Submarine to enter Mariana’s Veil. It’s going to take more than a pair of flippers and an air tank to visit the area. So, the Submarine it is, and like it was with accessing Atlantis, there’s an entire quest dedicated to getting it in Roblox Fisch. And the best part? It doesn’t cost a cent!

Go to Roslit Bay, and instead of stopping at the docks you normally would, aim for the lighthouse. There’s a new dock there, and Dr. Glimmerfin is there. Speak with him, and he’ll give you the details: he had to abandon his submarine, and the parts are scattered around Roslit Bay.

But here’s the catch: the submarine parts are encased in obsidian rocks. They’re scattered all over the island, but luckily, Dr. Glimmerfin gives you the Drill for free. You’ll use that to break open the obsidian rocks and, hopefully, find all five pieces of his submarine. It’s not guaranteed you’ll get a piece; in fact, there’s just a 5% chance.

Just behind the lighthouse are a bunch of obsidian rocks that spawn very fast. I had all five pieces within 10 minutes of drilling. Take them back to where the outline of the submarine is (by Dr. Glimmerfin), attach each piece, and then talk to him again.

You can now access Mariana’s Veil! The submarine will spawn nearby. If you ever want to spawn it again, speak with Dr. Glimmerfin. However, if you want to spawn it from the Shipwright, you must be level 70.

How to Survive Mariana’s Veil in Roblox Fisch

When you get into Mariana’s Veil, eventually you’ll come to lava. At that point, a temperature gauge will appear and gradually increase. You will die if that happens. However, you can upgrade your submarine and craft a Glimmerfin Suit, which comes in handy for when you want to head deeper into Mariana’s Veil to fish in the lava.

At the Volcanic Vents (that’s the first dock inside Mariana’s Veil in Roblox Fisch), you’ll see a pedestal that requires specific items:

Lava Crystal: Obtained from mining the strange lava veins at Volcanic Vents.
Inferno Hide: Obtained from fishing in the water at Volcanic Vents.
Blisterback Blenny: Obtained from fishing in the water at Volcanic Vents.
Infernal Iguanafish: Obtained from fishing in the water at Volcanic Vents.

Take those to the pedestal and the upgrades are yours! You have to wear the Glimmerfin Suit to reduce the heat buildup.

One last point of interest: if you head further into Mariana’s Veil, you’ll find a lava pool to fish in (which you need at least the Magma Rod for) and the Volcanic Rod. It costs $300,000 and has a 20% of granting the Ashen Fortune mutation, which multiplies the value of fish by five.
