What are the best domains to farm for Ocean-Hued Clam artifacts in Genshin Impact?

To farm Ocean-Hued Clam artifacts in Genshin Impact, you need to focus on the Slumbering Court domain, located on Watatsumi Island in Inazuma. This domain is the only source of Ocean-Hued Clam artifacts, which are highly valuable for healers like Kokomi, Qiqi, and Barbara. The Ocean-Hued Clam set provides a significant boost to healing effectiveness and converts excess healing into damage, making it ideal for characters who excel in healing and support roles.

The Slumbering Court domain is unlocked after completing the Archon Quest "Ritou Escape Plan" and reaching Adventure Rank 30. Once unlocked, you can access the domain by traveling to Watatsumi Island and interacting with the domain entrance. The domain has different levels of difficulty, with higher levels offering better chances to obtain 5-star artifacts. To maximize your farming efficiency, you should aim to clear the highest difficulty level you can handle, as this will give you the best rewards.

When farming the Slumbering Court domain, it is important to consider your team composition. The domain features enemies that are weak to Electro and Cryo elements, so bringing characters like Raiden Shogun, Fischl, or Ganyu can make the runs smoother. Additionally, having a strong healer or shielder in your team, such as Zhongli or Bennett, can help you sustain through the domain's challenges. A balanced team with a mix of DPS, support, and healing characters is recommended to ensure you can clear the domain efficiently.

For artifact optimization, focus on obtaining the Ocean-Hued Clam 4-piece set bonus, which increases healing effectiveness by 15% and creates a Sea-Dyed Foam that deals damage based on 90% of the healing amount. This set is particularly effective on characters who can consistently heal, such as Kokomi or Qiqi. When selecting artifacts, prioritize main stats like Healing Bonus on the Circlet, HP% on the Sands, and Hydro DMG Bonus or HP% on the Goblet. Substats should focus on HP%, Energy Recharge, and Elemental Mastery to enhance your character's healing and support capabilities.

Weapon choices for characters using the Ocean-Hued Clam set should complement their healing and support roles. For Kokomi, the Everlasting Moonglow is the best-in-slot weapon, providing HP% and healing bonuses. Alternatively, the Prototype Amber is a strong free-to-play option that offers Energy Recharge and healing benefits. For Qiqi, the Sacrificial Sword is a great choice, as it allows her to use her Elemental Skill more frequently, increasing her healing output.

Resource management is crucial when farming artifacts. Original Resin is required to claim rewards from the domain, so it is important to use it wisely. Prioritize using Condensed Resin, which allows you to claim double rewards for the same amount of Resin. This can save you time and increase your efficiency. Additionally, plan your farming sessions around your daily Resin regeneration and consider using Fragile Resin if you need to farm a large number of artifacts quickly.

Common mistakes to avoid include neglecting your team's elemental synergy and failing to optimize your character's artifacts and weapons. Ensure that your team has a good balance of elements and roles to handle the domain's challenges. Also, avoid farming lower-level domains, as they have a lower chance of dropping 5-star artifacts. Always aim for the highest difficulty level you can manage to maximize your rewards.

Advanced techniques for farming the Slumbering Court domain include using food buffs and potions to enhance your team's performance. Dishes that increase ATK, CRIT Rate, or Elemental DMG can give you an edge in combat. Additionally, using characters with crowd control abilities, such as Venti or Kazuha, can help you manage groups of enemies more effectively.

In summary, farming Ocean-Hued Clam artifacts in Genshin Impact requires a strategic approach to team composition, artifact optimization, and resource management. Focus on the Slumbering Court domain, use a balanced team with strong elemental synergy, and prioritize high-level domains for better rewards. By following these strategies and avoiding common mistakes, you can efficiently farm Ocean-Hued Clam artifacts and enhance your healing characters' performance.
