Fisch Volcanic Vents Guide
The Volcanic Vents are the first area you will come across in the Cave System. If you can’t find it, you can head to these coordinates: X: -2745, Y: -2325, Z: 865. The Submarine Upgrade in the Volcanic Vents has to be unlocked before you can travel deeper.
As you need to unlock the Submarine Upgrade first, your only option is to enter the tunnel to obtain the upgrade. At the end of the tunnel is a cave, which is where you will find the upgrade station to obtain the Heat Upgrade.

- Then, start fishing inside the Volcanic Vents to obtain the following:
- x1 Infernal Iguanafish
- x1 Blisterback Blenny
