Basics
•Location: Mondstadt: Found in the Springvale area, specifically at the "Falls of Concentration" to the northwest of Windrise.
•Element: Hydro: All its attacks and mechanics involve the Hydro element, dealing water-based damage.
Combat Mechanics
•Initial Phase: The Oceanid starts by summoning Hydro mimics or slimes which you need to defeat to trigger the next phase.
•Core Exposure: After clearing the slimes, the Oceanid's core becomes vulnerable, allowing you to attack it directly.
•Regeneration: After taking damage or after a set time, it will regenerate, summoning new slimes or changing its pattern.
•Elemental Shield: Sometimes, various elemental shields (Hydro, Electro, Cryo) will appear around the arena. You need to break these with the corresponding element to proceed.
Attacks
•Hydro Mimics: Summons Hydro slimes that can attack with water jets or explode upon defeat.
•Elemental Slimes: Sometimes, slimes with Cryo, Electro, or Hydro shields appear, which must be dealt with using appropriate elemental attacks.
•Water Pillars: Summons pillars of water that chase you. These can be destroyed but regenerate if not taken down quickly.
•Flood: Occasionally floods the arena, dealing persistent Hydro damage if you stay in the water.
•Water Spheres: Creates orbs of water that can move around or explode upon contact.
Strategy 
•Destroy Slimes Quickly: Focus on quickly eliminating the slimes to reach the Oceanid's core phase.
•Use Elemental Reactions: Electro-Charged (Hydro + Electro) can help with crowd control. Vaporize (Hydro + Pyro) for increased damage on slimes and the core. Shatter (Cryo + frozen Hydro) can be effective against slimes that might freeze.
•Positioning: Stay aware of your surroundings to avoid being cornered by water pillars or caught in Flood attacks.
•Shield Management: When elemental shields appear, switch to the corresponding element to break them swiftly.
Recommended Team Composition
•Electro: Fischl or Beidou for dealing with multiple slimes and elemental reactions.
•Hydro: Xingqiu for consistent Hydro application or Barbara for healing.
•Cryo: Kaeya or Diona for Cryo shields and reactions.
•Flex Slot: Bennett for healing and Pyro application or another character depending on your needs (more DPS, Electro, etc.).
Tips: 
•Elemental Mastery: Characters or artifacts with high Elemental Mastery can amplify the damage from reactions like Electro-Charged or Vaporize.
•Energy Recharge: Having good energy recharge on your team ensures you can use your elemental skills and bursts frequently, which is crucial for breaking shields and dealing with slimes.
•Avoid Flooded Areas: Move out of areas that turn into water to prevent taking continuous Hydro damage.
•Focus Fire: When the core is exposed, concentrate all your damage on it. Use bursts and skills that can deal high damage or area damage.
•Terrain Use: The area has natural cover; use this to your advantage to dodge or reposition during battles.
Rewards
•Sea Ganoderma (Sliver, Fragment, Chunk, Gemstone): Essential for ascending Hydro characters like Barbara, Xingqiu, Tartaglia (Childe), Mona, etc.
•Energy Nectar: A unique drop for ascending Hydro characters.
•Artifacts: You might receive artifacts from sets like Berserker, The Exile, Instructor, Gladiator's Finale, or Heart of Depth (which is particularly useful for Hydro characters).
•Companionship EXP and Mora: Useful for increasing friendship levels with characters and for in-game currency.
General Strategy Recap
1.Preparation: Equip your team with a variety of elements to handle all types of slimes, and consider characters with high Elemental Mastery for better reactions.
2.Execution: Focus on quickly defeating the slimes to expose the Oceanid's core.
3.Use elemental reactions to your advantage for both crowd control and damage.
4.Stay mobile to avoid Hydro-based attacks and flooded areas.
5.Switch to your strongest DPS characters when the core is exposed for optimal damage output.
6.Adaptation: If one strategy isn't working, consider switching tactics or team composition. Maybe bringing more healing or focusing on different elemental combinations could make the fight easier.
Co-op Mode
•If you find the Oceanid challenging solo, co-op can be particularly effective. Multiple players can distribute the focus of the slimes and Oceanid, allowing for quicker shield breaking and more frequent opportunities to damage the core.
Fighting the Oceanid, or Flowing Pride, requires strategic use of elemental reactions, efficient slime management, and high DPS during core exposure phases. With these tips in mind, you'll be well-prepared to gather the necessary materials for ascending your Hydro characters in Genshin Impact.
