Fisch Submarine Heat Upgrade and Glimmerfin Suit Guide

Want to know everything about the Submarine Heat upgrade and Glimmerfin Suit in Roblox Fisch? The Heat upgrade is essentially required to navigate your submarine through high temperature regions in the Mariana’s Veil. Here’s a detailed guide explaining everything about the Submarine Heat upgrade and Glimmerfin Suit in Fisch.

How To Unlock Submarine Heat Upgrade and Glimmerfin Suit in Fisch

To unlock heat upgrade for your submarine, you must head to the Volcanic Vents. Its entrance is located at GPS coordinates -2745, -2325, 865 inside the Mariana’s Veil.

Once you reach the other end of the Volcanic Vents, you’ll find a Required Resources menu that lists all the materials required to unlock the Heat Upgrade. Here’s the list of materials you’ll need:

• Lava Crystal x1: Drill the rocks in Volcanic Vents. Rocks can be found in the cave at -3365, -2260, 3850. Each Rock takes 5 Drills to break and broken rocks respawn after a few seconds
• Inferno Hide ×1: Fish in the Volcanic Vents
• Blisterback Benny ×1: Fish in the Volcanic Vents
• Infernal Iguanafish ×1: Fish in the Volcanic Vents

To fish in the Volcanic Vents, you must cross a lava obby which can be accessed through a cave to the South. The obby as usual, features a bunch of obstacles and geysers that can burn a player. We recommend using an advanced glider to quickly clear it.

At the end of the obby, you will find a lava pool where you can fish to get Inferno Hide, Blisterback Benny, and Infernal Iguanafish. You can also purchase the Volcanic Rod at this location (-3175, -2035, 4020), for 300,000C$.

Once you have all four parts, you must once again interact with the Required Resources menu and you will finally unlock the Submarine Heat Upgrade along with the Glimmerfin Suit Lvl 1.
