Fisch Deep Update – Full Guide to Beacons, Rods and the Sunken City

The Deep update has landed in Fisch, and it is easily one of the biggest expansions the game has seen. We are talking about a sunken city, four dark trenches, dozens of new fish, and a crafting grind that will keep us busy for weeks. If you have been holding off on jumping in, here is everything we know about the update and how to make the most of it.

This update adds a massive underwater region hidden beneath the ocean, complete with a lost city, breathable districts, and NPCs who hand out new quests and rewards. It also brings new rods, harpoon guns, spears, and three fresh bestiaries packed with over sixty fish species. We have spent hours exploring the update, and we want to break down exactly how it works so you do not waste time getting lost.

How to Reach the Deep

Getting into the Deep is simple once you know where to look. Head toward Castaway Cliff and look for three question marks marked off in the distance. Swim through that area, and you will cross an invisible border that teleports you straight into the new zone. From there, turn toward the deeper water, and you will spot a small boat.

Before swimming further down, talk to the NPC standing near that boat. This step matters more than it looks. Skipping this conversation means missing out on a required survey device, and that device is what lets you survive and move properly once you go deeper. We would not recommend rushing past this part just to explore faster.

Once you pick up the device from the questline, equip it through your accessories. It controls your oxygen and your movement, so treat it as mandatory gear rather than an optional extra.

Beacons and the Main Storyline

The heart of the update revolves around five beacons scattered across the Outer Deep. Each beacon sits dark until you complete a quest chain for a specific NPC and hand over a crafted core. Lighting a beacon brightens its section of the map and calms down some of the aggressive fish nearby, which makes fishing noticeably easier.

We found the beacon questlines repetitive on paper but genuinely satisfying in practice, mostly because each one rewards a real upgrade. A few things worth keeping in mind as you work through them:

• Never sell anything you catch early on, since many quests ask for specific fish or materials you may have already caught.
• Keep an eye on the bounty board near the main questgiver, since it refreshes often and hands out useful materials fast.
• Common materials like bone shards and prism scales drop from multiple fish, so you rarely have to hunt one exact species.

Completing all five beacons unlocks a master questline that eventually rewards an upgraded survey device with a stronger radar, plus access to the Gloomy Crevice’s darkest corners.

New Rods Worth Chasing

Four new rods headline this update, and each one demands a different kind of grind. The Luminous Rod comes first and is relatively easy to unlock through a straightforward material turn-in. It leans on luck and lure speed rather than raw power, which makes it a solid pick for players still building their bestiary.

The Scalding Hook takes more patience, as it requires a rare harpoon piece before you can even start crafting it. Its passive heats up over several seconds and speeds up your catch progress, which we found genuinely useful during longer fights.

The Titanium Rod is where the grind escalates. You need to complete four separate NPC questlines just to gather its two main components, and it’s locked behind level 250. The payoff is worth it though, since it brings near-permanent lure speed and a generous stat spread.

Finally, the Cusk Purger sits at the top of the ladder. Crafting it requires hunting down the Monstrous Cusk, a multi-stage chase that starts in the Gloomy Crevice and ends with a harpoon fight near Deep City. We recommend using a harpoon with strong burst damage here, since the fight punishes slow reactions.

Harpoons, Spears, and the Grind Ahead

Alongside the rods, the update introduces new harpoon guns including the Scrap Cannon, Titanic Scalder, Cusk Shot, and Sightless Oracle. Most of these share crafting materials with the rod questlines, so working on both at once saves a lot of backtracking. The Sightless Oracle stood out to us the most, thanks to a passive that noticeably enlarges catch zones and rewards precise clicking.

Three new spears round out the crafting list: the Chitin Piercer, Bone Lance, and Prism Spear. The first two only need common materials and a modest level requirement, while the Prism Spear demands a specific mutation on a rare squid, making it the hardest of the three to finish.

Our Final Thoughts

The Deep update rewards patience more than raw grinding speed. Every questline overlaps with another, so the smartest approach is holding onto every material you catch rather than selling early for quick cash. Players chasing full completion should also expect a long road ahead, since some of the deepest rewards only unlock after finishing nearly every quest tied to the update.

If you are diving in this week, focus on the beacons first. They light up the map, calm down hostile fish, and hand you the core materials needed for almost everything else in this update.
