A Complete and Full Guide to the Deep Update in Fisch | From Entry to Crafting the New Rods
We are here to talk about the Full Guide to Deep UPDATE in Fisch. The current update is one of the biggest updates to the game and includes a full sunken ancient city that will introduce over 60 new fish species and new rods and equipment.

All about The Route to Reach the Deep
What we recommend at first is to head to Sunstone Island by boat. Once there, follow the path behind the island to find the entrance to the underwater area. If you continue in the same direction, you will automatically be transported to the deep area.
Get the First Item and Enter the City
After you enter the underwater area, you can see an NPC near a small boat nearby. Continuing the path ahead requires talking to this NPC. Because talking to him will give you an item that, if you carry it with you, will lead you to the second NPC underwater, the Galaxy, located near the central castle.
Obtain the Deep Survey Device
This second NPC inside the castle will take you to the Deep Survey Device. This device is one of the essential pieces of equipment in this update that allows the player to walk on the ocean floor instead of swimming. If the player has this ability, they can even throw a fishing rod into the water while walking in the ocean.
What Are the Three Main Areas to Explore
This Full Guide to Deep UPDATE in Fisch tells you that after receiving the Deep Survey Device, three main areas will open up for you to explore. These three areas are: 1. Outer Deep, which is a good place to start exploring as the first layer, 2. Gloomy Crevice, which is a dark area full of ruined infrastructure. Note that to explore this area you need to upgrade the device to MK II and unlock its light module, and 3. The third area is the Lower Deep, which is the deepest layer and is located at the bottom of the underwater map.
Current Update Includes New Rods
Deep UPDATE in Fisch adds four brand-new rods, namely Luminous Rod, Titanium Rod, Scalding Hook, and Cusk Purger. The hardest recipe to craft is the Cusk Purger. The easiest and most straightforward method to craft is the Titanium Rod.
What Materials Are Required to Craft the Cusk Purger
Crafting the Cusk Purger requires items that are best kept rather than sold due to their direct connection to specific deep-level activities. These materials are as follows:
- Three Cusk Teeth
- Refined Scrap
- Hardened Chitin
- Abyssal Bio-Fluid
- Prism Scale
- Ancient Bone
Additional Gear Such as New Harpoon Guns and Spear
Other equipment added to Deep UPDATE in Fisch are four new harpoon guns and one new spear. What these equipment bring to you in the current update that was not in the game before is the ability to attach bait directly to ranged weapons like harpoons and spears. The names of these equipment are as follows.
- Cusk-Shot
- Scrap-Cannon
- Titanic Scalder
- Sightless Oracle
- Prism Spear
New Companion and Fresh Bestiaries in This Update
In the current update, you'll also be introduced to a new companion called Scrap-Bot and three new Bestiaries that have been added to the game's pre-existing fish species by copying real aquatic creatures.
