In Assassin’s Creed Odyssey, accessing underwater ruins and sunken treasures is vital for exploration and the completion of the “Child of Poseidon” achievement, which requires you to discover all 42 underwater locations throughout the game’s vast map. Below is a detailed guide on how to effectively loot these underwater sites and maximize your treasure hunting experience.

How to Access Underwater Ruins and Sunken Treasures

1. Unlock the Diving Ability:
– The ability to explore underwater becomes accessible early in your journey, specifically after you unlock your ship during Sequence 2 of the story. This pivotal moment allows your character to dive beneath the waves and investigate sunken locations, making it the first step toward your underwater adventures.

2. Utilize Your Eagle for Marking:
– Before diving into the depths, use your eagle to scout the surrounding waters. This not only helps in locating hidden treasures but also allows you to mark underwater points of interest on your map. Remember that this feature significantly enhances your efficiency when planning your dives.

3. Diving and Exploring:
– Swim down to the marked locations, which typically include various shipwrecks, ruins, and hidden treasure chests. Each site may contain valuable loot such as weapons, gear, or quest items. Take the time to navigate through these areas thoroughly to ensure you collect all available treasures and collectibles.

4. Clearing the Location:
– After looting, make it a priority to fully clear each underwater site. This means collecting all loot and defeating any enemies present. Successfully doing so will mark the location with a checkmark on your map, confirming that it is completed and contributing towards your achievement progress.

5. Locked Chests and Keys:
– Be aware that some underwater ruins, including significant locations like the Underwater Ruins of Arne, feature locked chests. Accessing these chests often requires you to find specific keys located nearby or to solve environmental puzzles. Engaging with these challenges can yield even greater rewards.

Tips for Efficient Underwater Looting

– Pre-Scout with Your Eagle: Always use your eagle to survey the area before diving in. This will give you a strategic advantage in knowing where to go first.
– Manage Your Breath Meter: Be conscious of your character’s breath meter. Surface for air when necessary to avoid drowning and losing progress in your exploration.
– Cautious of Hazards: Some underwater locations may harbor enemies or hazardous conditions, so approach with caution and be prepared for combat.
– Search for Keys and Clues: Make sure to search the immediate vicinity of locked chests for keys or other clues that might help you unlock them.

By systematically exploring these locations, marking them with your eagle, and thoroughly collecting all loot, you will navigate the underwater world of Assassin’s Creed Odyssey with ease. Successfully completing these tasks not only enhances your gameplay experience but also leads to finishing the “Child of Poseidon” achievement and adds a rich layer to your adventure in ancient Greece.
