1+Sea Prisoner is an Anomaly Hunt encounter in Neverness to Everness. The fight takes place in Nautili Tunnel and is part of the game's weekly combat loop. Sea Prisoner is weak to Anima damage.24Lore and Description46A massive, constantly suffering whale bound by whaling-ship chains. The creature searches for someone powerful enough to help destroy its bindings. Its song is a cry for help, audible across the Nautili Tunnel zone before the encounter begins.68Quick Facts810AttributeValueCategoryAnomaly Hunt EncounterSubtitleOpen-world weekly encounterLocationNautili TunnelWeaknessAnimaStamina Cost per Attempt60 StaminaChallenge Levels8ResetWeeklyWorld Boss IDBoss_19_BP_WorldBossMap Markermonsters:boss_19:01012Strategy and Mechanics1113Mechanics1315Interrupt the Sea Prisoner's Dash Attack with a well-timed Parry Attack. A clean parry resets the chain swing and opens a long burst window during which the boss is helpless.1517Recommended Team1719The team picks below are aligned to the Anima weakness. Pulling any of these into the active rotation is the highest single-stat increase you can apply to Sea Prisoner's clear time.1921EsperRarityElementJiuyuan5-StarAnimaNanally5-StarAnimaMint4-StarAnima2123General Combat Guidance2224Fill the boss's break meter with consistent attacks and reward-heavy defensive inputs. Successful parries and dodges contribute significantly more to the break bar than a hit, and a clean parry also fills the Esper Cycle Meter instantly. Save ultimates and heaviest skills for the stagger window that follows a full break. Sea Prisoner takes greatly increased damage while staggered, so burst output during this phase largely determines whether the encounter clears quickly. Build the team around the Anima weakness. Characters aligned with Anima will see the largest damage multiplier, and team compositions that can enable elemental reactions on top of that attribute will apply additional pressure to the break bar between stagger windows.2426Weakness and Resistances2628The table below lists the boss's raw resistance value for each of the six elements. A lower number marks the element the boss is most vulnerable to.
