Lost Diver location in Fisch: Where to rescue the Lost Diver
The Lost Diver is located deep in the Underwater Opening near Tidefall, next to a submerged, wrecked submarine. He does not appear on the surface and cannot be reached by swimming down normally without equipment.
The spawn area is at the bottom of a deep-sea zone close to the Tidefall region, roughly around the coordinates 3223, 130, 850.
What you need before searching for the Lost Diver
| Item | Why it’s required |
|---|---|
| Submarine or Jet Ski or Boat | Allows safe descent into deep-sea pressure |
| Advanced Diving Gear | Prevents drowning after exiting the sub |
| Flippers / Super Flippers | Faster swimming to and from the wreck |
| Movement buffs (optional) | Helps during the return trip |
Without these, oxygen drain and depth pressure will stop you before you reach the diver.
How to find the Lost Diver in Fisch
Travel to the Tidefall region and head toward the deep-ocean marker near the coordinates listed above. Enter your submarine or ski. The submarine will stop before reaching the ocean floor, which is normal.

While you are on your way to Tidefall, look for 4-5 ships clustered at a spot. This is the cue for the Lost Diver location, which is in the Underwater Opening Area.

Exit the submarine once it can’t descend further into the Underwater Opening area. Equip your Advanced Diving Gear and Flippers immediately.

Swim downward toward the wrecked submarine visible near the bottom of the zone. Look beside the wreck to find the Lost Diver NPC.

Interact with him (default E key) to pick him up. Swim back upward and return to the surface. Use movement boosts if available to avoid oxygen or pressure damage.

What happens after rescuing the Lost Diver
The Lost Diver isn’t hard to find once you know where to look—but preparation is everything. Bring a submarine, gear up properly, and head straight for the wrecked submarine near Tidefall to finish one of Fisch’s most important progression quests.
