A jealous doctor has taken Nate, while Miso waits in the cave for a rescuer to find him. Getting Nate back means cracking a computer PIN, locating two blade pieces, completing a lengthy set of fishing tasks, and facing the doctor far below the surface. The quest takes time, but its route is predetermined once you know the way.
Quick answer: At Nate’s Cave on Sunstone Island, find Miso and enter your own four-symbol PIN. Recover the Broken Blade and Crimson Centerpiece, then reforge the blade. Pass the Moosewood, Volcano and Snowcap catch trials, then follow the trail of Nate’s possessions through Desolate Deep to his hideout.
Start Nate’s Quest at Nate’s Cave on Sunstone Island
Go to Sunstone Island and make your way to Nate’s Cave, around -914.0, 207.4, -1027.8. Look for the entrance on the small cliff behind the Merlin Witch NPC; it isn’t on the beach below. The cave contains a furnished home: a car by the entrance, a sofa, a bedroom, and a desk upstairs.
Miso, Nate’s cat, is resting by the desk. Interact with the cat to open the dialogue and start the investigation. Miso points you toward Nate’s computer, which is locked behind a PIN made of symbols.

Add to Google Preferences →Solve the four-symbol computer PIN
The terminal in Nate’s cave needs four symbols entered in sequence. Your symbol combination is randomized, so locate all four within the cave. The cave itself contains everything you need; searching the sand outside won’t help.
PINs are unique to each player, so another player’s combination won’t work. Use the four symbols assigned to your character.
- Find the first symbol atop the stool beside the bedroom, on the computer’s left.
- Behind the sofa, check the bookshelf for symbol 2.
- Near the cave entrance, find the third symbol on the car’s front seat.
- You’ll find symbol 4 on the computer desk’s left side.

Input all four symbols at the terminal in their correct sequence. If you’ve found just three, cycle the choices in the final slot until the PIN works. The correct combination triggers a kidnapping video log and moves the quest forward to fixing the shattered blade.
Recover the two blade fragments
Restoring the weapon takes two parts: the Crimson Centerpiece from Crimson Cavern and the Broken Blade from the Depths Maze. One is a fishing drop and one is a direct pickup, so expect some grinding alongside the exploration.
Crimson Centerpiece in Crimson Cavern


Broken Blade in the Depths Maze


Forge the restricted blade at Nate’s Cave
Carry both parts back to Nate’s Cave and place the Broken Blade and Crimson Centerpiece on the table in front of the sofa. That reassembles Nate’s Blade, but it comes back in a restricted form. The weapon exists in your hotbar now, yet its abilities stay locked until you finish the trials below.

Unrestrict Nate’s Blade through the fishing trials
Three catch trials remove the restrictions, each at a different location, and all of them must be done with Nate’s Blade equipped. Bring a rod with strong line strength and control so you do not snap on the harder bites.

Snowcap Cave: perfect-catch 20 Colossal Squid
Enter the Snowcap Cave and fish the exclusive pool for Colossal Squid. The squid is a Mythical catch that bites at night in foggy weather, with any bait. You need 20 perfect catches to clear this stage.
Finish the collection challenges
After the three trials comes an extended collection task. Check the Quest Book for the exact remaining targets. This is the quest’s longest section: finish the fixed-count objectives for boats, lanterns, titles and badges first, then tackle the other listed requirements.
- Catch every original fish with Nate’s Blade (0/126)
- Catch 5 fish using each original Fishing Rod (0/15)
- Collect all 45 obtainable original Titles that are free (0/45)
- Obtain every original Boat (0/10) and Lantern (0/11)
- Unlock every original Badge (0/30)
- Enchant 21 times (0/21)
- Witness every original Weather and Modifier (0/8)
Once everything is checked off, return to Miso in Nate’s Cave to confirm the blade is fully unrestricted.
Track Nate through Desolate Deep and finish the rescue
Once Nate’s Blade has no restrictions, enter Desolate Deep and look for the trail left by Nate’s belongings. Pick them up in order instead of searching the open water without a plan.
- Nate’s Crown is perched atop the Desolate Deep Buoy.
- Look beside the white sign board in Desolate Deep to find Nate’s Glasses.
- You’ll find Nate’s Lantern in the cave tunnel close to the Reinforced Rod.
Cast your fishing rod at the wooden door or wall in the tunnel to break it open and enter Dr. It Fish’s Lair. Interact with Dr. It Fish and view the cutscene, then speak to Nate to rescue him and claim a boat reward. The tracker completes the quest when it records Nate’s rescue; afterward, check the Quest Book and rewards to verify completion.
Unlock Miso as a companion
Once Nate is safe, go back to Nate’s Cave on Sunstone Island. Pick up the cheese hidden in a living-room corner and give it to Miso. This permanently unlocks the cat as a companion you can equip.
Redeem the SaveNate code
A quest launch code was also released. While it’s active, redeem SaveNate from Fisch’s in-game code menu. Preserve the code’s capitalization, and claim it soon because codes may expire without warning. An in-game confirmation appears when redemption succeeds.
