Whether you are looking for the Sea Prisoner boss location in Neverness To Everness (NTE), want to know how to complete the Deep Blue Sorrow Anomaly Commission, or want to know how to get the Song of the Whale S-Rank Plasma-Type Arc or such things, I’ve got you covered with this guide.
Sea Prisoner is yet another boss, like the Nestbound Bird, Black Tome, Swallowtail, and Headless Rider, who gives players a free S-Rank Arc and unlocks the boss for farming upgrade materials.
Like others, the boss is associated with one of the Anomaly Commissions, Deep Blue Sorrow.
Moreover, the free S-Rank Arc that it gives is a good free option for Plasma-Type characters, such as Aurelia and others.
With that said, here’s the complete guide on the Sea Prisoner boss.
Song of the Whale S-Rank Plasma-Type Arc
In NTE, you can unlock the Song of the Whale S-Rank Arc by defeating the Sea Prisoner boss for the first time.
Once you do that, the Anchor within the boss’s body will manifest in the arena. Head there and ‘Contain’ it.
Doing so will unlock the Song of the Whale Arc and add it to your inventory.
Song of the Whale Arc stats
The Song of the Whale is a great Plasma-Type S-Rank Arc with ATK% as secondary stats, with a unique skill called Deep Blue Sorrow.
It further increases the ATK and also restores HP if you meet the criteria, which is defeating any enemy when it’s staggered.
Deep Sea Blue Anomaly Commission and Sea Prisoner boss location
Start the Deep Sea Blue Commission via the ‘Anomaly Commission’ option accessed through any of the Weitherheimer Towers or the Exploration Guide > Anomaly Hunt.
Once that is done, the search area for the Sea Prisoner boss will be marked on your map. It is within the Nautili Tunnel, as you can see in the above screenshot.
Boss spawn notes
You cannot spawn the boss if you are on a bike. Also, while some YouTubers and creators say that you have to drive a car backward and whatnot, it is not TRUE.
Just ensure you are in a car. If the boss doesn’t spawn, access the tunnel from the other side, and also try changing the time to nighttime. Around 8:00 or 9:00 is fine, though not mandatory.
Once you are in a car, drive through the tunnel.
If done correctly, you will get the Anomaly warning, and the portal will spawn. Keep driving.
Once you are past the portal, keep driving on the straight path until you find yourself in the boss arena.
Defeat the boss.
Sea Prisoner boss location
Once you defeat the Sea Prisoner boss for the first time, the boss icon will become available at the above location. Now you can farm the boss for materials.
Sea Prisoner boss drops
Here are the different drops that you can get from the Sea Prisoner boss:
- Tear of the Sea Development Material
- Beetle Coin
- Magic Thread
- Arcane Thread
- Hunter Level EXP
