Quick Facts

Strategy and Mechanics

Mechanics

Interrupt 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.

Recommended Team

The 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.

General Combat Guidance

Fill 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.

Encounter Notes
