The Deep Main Quest in Fisch requires you to restore power to four different towers. Each tower needs a specific set of materials, which you must collect and use to create the item needed to restore it. In this guide, we’ll explain where to find each tower, what materials you need, and how to complete the quest.
How To Complete The Deep Main Quest
To complete the Deep Main quest, you need to restore the power of 4 towers. For that, you will need to collect different types of items to restore the towers. To collect the items, use the Toxinburst Rod passive ability.
First Tower
Start from the Main quest NPC and from there go east towards the Outer Deep. This one is called Hunter Dan. In this tower, you will need:
- 10× Bone Shard
- 5× Prism Scale
- 1× Abyssal Bio Fluid
You will need these items to synthesise the Hydro Core. Now install the Hydro Core in Sector 1P-1. Restoring this tower will reward you with 12k currency and 6k Experience Points.
Second Tower
From the location of Tower 1, go towards the northwest. There, you will find the Cartographer. To restore this tower, you will need:
- 15× prism scale
- 10× Bio Fluid
- 1× Ancient Bone
Collect the required items to synthesise the Abyssal Lens. Now install the Abyssal Lens in Sector 1P-2. Restoring the tower will reward you with 14k currency and 6,500 Experience Points.
Third Tower
Now, to reach the third tower, start from the Main quest NPC and go towards the right direction. Move forward to reach a cave, and at the end of it you will find a room. Inside the room, you will find Doctor Vane. To restore this tower, you will need:
- 20× Bone Shard
- 15× Salvage Scrap
- 1× Radiant Prism Scale
Collecting these items will allow you to synthesise the Bioluminescent Battery. Now, install it in Sector 1P-3, restoring the tower in Sector 1P-3. Restoring the tower will reward you with 16k currency and 7000 Experience Points.
Fourth Tower
From the Main quest NPC, go west to find Sledge. To restore this tower, you need:
- 25× Chitin Plate
- 20× Salvage Scrap
- 1× Refined Scrap
- 1× Hardened Chitin
Collecting this will allow you to synthesise the Reinforced Housing. Now, install it in Sector 1P-4 to get 18k currency and 7,500 Experience Points.
After restoring the towers, you can return to the NPC to get the Deep Survey Device MK II. The Deep Survey Device MK II is a useful device in the Deep update for Fisch. It gives you night vision, making it easier to see underwater, and also has a fish radar that shows you the names of nearby fish.
How to Reach The Deep
First of all, go to Castaway Cliffs at GPS (690, 135, -1693). Then go towards the north until you pass the open Ocean area. Pass through a small barrier that will take you to the opposite side of the Ocean. Once teleported, get to the following coordinates (228, 130, -11945). There you will find a ship with the inscription “The Deep” at the top of it. Before interacting with the NPC standing on the ship, make sure to equip yourself with:
- Flipper
- Oxygen Tank
- Tidebreaker
- Diving Suit
After that, enter the ship and talk to Cadet Shimmerfin. Once you complete the conversation, move towards the Anchor at the end of the ship. Diving into the water while holding Tidebreaker, move towards The Deep.
