Navigating the extreme depths of Mariana's Veil in the Roblox experience Fisch requires more than standard diving gear. The Volcanic Vents serve as the fiery entry layer to this underground abyssal zone, forcing players to master unique mechanics like heat accumulation and submarine transit. If you're struggling to survive the crushing pressure or trying to farm rare fish species near the hydrothermal chimneys, you need a precise blueprint of the area.
This guide breaks down how to access the Volcanic Vents, bypass the crushing water pressure using a submarine, complete the essential heat upgrade, and secure the best catches without getting cooked.
Locating and Entering Mariana's Veil
The Volcanic Vents are tucked deep beneath Roslit Bay. You can't just swim down there with basic equipment; the water pressure will crush your character instantly. Reaching this zone requires constructing a submarine at the Submarine Depot.
To build your submersible, you must gather five submarine parts. These components have a small chance of being drilled from rocks scattered around the bay reef. Once you've successfully extracted all five parts and returned them to the depot, a cutscene clears the magma blocking the shaft, granting you a spawnable submarine.
Pilot your submarine straight down into the cave system to bypass the instant-kill pressure mechanics. If you ever need a quick exit back to the surface, look for the portal located at coordinates -3495, -2255, 3825.
Surviving the Heat System
Once you step out of your submarine inside the Volcanic Vents, a secondary hazard kicks in: the heat system. The environment continuously radiates intense thermal energy, causing your heat meter to climb the longer you stay exposed.
- Temperature Protection: While standard diving gear protects against pressure, you'll need specialized upgrades to resist ambient volcanic heat.
- Safe Zones: Keep an eye on cooler stone pockets and ledges where your meter stabilizes briefly before you resume fishing or item collection.
- Movement Pace: Don't linger unnecessarily in open lava chambers unless you're actively casting your line for specific quest fish.
Securing the Heat Upgrade and Volcanic Rod
Progressing deeper into Mariana's Veil requires completing the Volcanic Vents heat upgrade. Head toward the center platform of the lava fishing cave where the upgrade station sits. To finish the upgrade, you need to catch three specific materials from the local lava pool:
- Inferno Hide
- Blisterback Blenny
- Infernal Iguanafish
Reeling these items in takes patience, as local catch rates favor persistent anglers equipped with heat-resistant lines. Once you collect all three items, turn them in at the local upgrade station.
While exploring this central platform at coordinates -3175, -2035, 4020, you can also purchase the Volcanic Rod for 150,000 C$. This rod is purpose-built for high-temperature zones and significantly boosts your catch efficiency when targeting magma-dwelling species.

Best Fishing Strategies and Money Farming
The hydrothermal activity makes this zone one of the most lucrative spots for mid-to-end-game cash grinding, especially when paired with server luck events or specific enchantments.
- Targeting Rare Species: Cast your line near the edges of the towering mineral chimneys where thermal currents attract high-value fish.
- Managing Inventory: Because trips back to the surface take time, bring a high-capacity tackle box to store your catches without cluttering your inventory slots.
- Avoiding Lava Hazards: Keep your footing secure on the parkour-style rock formations; falling into active lava pools forces an immediate respawn and wastes valuable expedition time.
Frequently Asked Questions
Do I need a submarine to enter the Volcanic Vents?
Yes. Swimming into Mariana's Veil without a submarine results in instant death due to extreme water pressure.
How do I get the Volcanic Rod?
The Volcanic Rod is available for purchase on a central platform inside the Volcanic Vents cave at coordinates -3175, -2035, 4020 for 150,000 C$.
What items are required for the Heat Upgrade?
You must catch an Inferno Hide, a Blisterback Blenny, and an Infernal Iguanafish from the local lava fishing pool and bring them to the upgrade station.
Can the Glimmerfin Suit protect me from the water pressure?
No. The Glimmerfin Suit protects against high temperatures, but a submarine is strictly required to shield your character from the crushing deep-sea pressure.
