Encountered during deep-sea exploration, the Deep Sea Leviathan is a colossal, aggressive marine creature guarding ancient ruins. Phases: It has two main phases. Phase 1 involves wide-area attacks, sweeping its tail and charging. Phase 2, when damaged, it will retreat slightly and summon smaller, aggressive fish to distract you while it recovers. Weaknesses: Its eyes are a critical weak point. Use a Harpoon Gun (crafted at Advanced Workbench) for maximum damage. Explosives can also stun it temporarily. Strategy: Approach with a well-equipped Submarine (for protection and mobility). Keep your distance and aim for its eyes. Clear out smaller fish quickly in Phase 2. Bring plenty of oxygen tanks and healing items. Rewards: Defeating the Leviathan grants access to the guarded ruin, often containing unique Ancient Artifacts and a large amount of rare deep-sea resources like 'Leviathan Scales' and 'Abyssal Gems'.
