How to build and upgrade

You will need a submarine to move across the Mariana veil surface in Fish. Unlike other boats in this experience, the submarine cannot be purchased from the ship’s writer. Instead, you will have to collect its parts from Roslit Bay before building it yourself. While building this underwater journey is not difficult, its promotion to withstand the ends of the Mariana veil is something that needs your undesirable interest.
Through our detailed guide below, you will learn how to build a submarine in Roslit Bay. The guide will also help you upgrade the submarine with heat, ice and deep promotions in Fisch.
How to make a submarine in Fish
Before you can start building a submarine, you will have to talk to Dr. Glimmerfin at the submarine warehouse. This area is located on the northwestern side of Roslit Bay. If you have GPSYou can find the submarine warehouse on the coordinates XYZ: -1305, 130, 310.
When talking to Dr. Glimmerfin, exercises that can be used to break the nearby rocks will be presented. Breaking these rocks will help you recover the required parts to build your journey. To build the submarine, you will need the following elements.
- X1 Windows
- X1 submarine higher
- X1 side
- X1 metal panels
- X1 back fins


The rocks that need drilling will get a healthy tape on top. Note that as soon as it is broken, each rock has a 5 % chance to drop the parts you need. Once you collect all parts, go back to the submarine warehouse and put each of them near the construction site. The position of all parts will successfully build a submarine that operates at full capacity.
After building the submarine, go back to Dr. Glimmerfin and talk to him to stir Cutscene. During this part, an underwater entrance will be opened, which allows you to insert it with a submarine.

How to get heat, ice and the deep upgrade of the submarine in Fish
While exploring the Mariana veil, you will face severe conditions. For example, you will suffer from severe heat in the volcanic openings, severe cold in the deep depth of Challenger, and the intense depth of Zenith Al -Habibi. The submarine will need to upgrade if you want to survive in these circumstances.
Here is how you can get upgrades to survive easily in every area in the Mariana veil.
Heat upgrade


Once the volcanic opening holes will be inserted, you will find an upgrade station next to the Roslit Bay Gate. You can bring the required elements to this station and adjust the submarine with heat upgrade. To upgrade the submarine, you will need the elements mentioned below.
- × 1 crystal lavaUse exercises to break the rocks in volcanic openings and obtain them.

Bring these elements to the upgrade station to adjust your submarine with heat upgrade. Aside from this, you will also receive a Glimmerfin 1 level. While you are underwater, this lawsuit should be prepared to keep your temperature.
Along with the submarine, the Glimmerfin suit also needs an upgrade to help you withstand conditions.

Deep upgrade


Upon reaching the Zenith Abyssal area, you will have to get a deep upgrade for the submarine alongside the level of the Glimmerfin 3 suit. You can do this by bringing the required elements to the upgrade station next to the Roslit Bay Gate. To indicate, we mentioned all the elements required to get the deep upgrade below.
- X1 fishermen lanternFind the pool with three large maintenance fish in it. Feed Orca Or Kraken to get this element.
- x1 Abyssal bearded seadevilUse a hunting rod to arrest this fish from the swimming pool in Zenith Abyssal.
