Basics
•Location: Mondstadt: Found in the area known as Stormterror's Lair, specifically in the cave right under the large tree where Stormterror perches.
•Element: Everything about its attacks and defenses is centered around the Anemo element.
Combat Mechanics:
•Shield Phase: The Hypostasis starts with a shield. This shield can be broken with any type of attack, but Anemo attacks may be slightly more efficient.
•Core Exposure: After the shield breaks, its core becomes exposed, and it becomes vulnerable. This is when you can deal maximum damage.
•Regeneration: After a while or when it takes enough damage, it will regenerate its shield. It might also change its attack patterns or summon wind currents or tornadoes.
Attacks:
•Wind Blades: Shoots multiple blades of wind from different directions. These can be dodged by moving continuously.
•Tornado: Summons a tornado that follows you, attempting to suck you in. You can dodge out of its range or use Anemo characters to disrupt it.
•Wind Mines: Places mines that explode with Anemo energy when you get near. Watch your step and use range or Anemo to clear these from a distance.
•Dash and Slam: It will sometimes dash towards you, followed by slamming down, creating a wind shockwave. Dodge to the side or jump over it.
•Updrafts: Can create updrafts that lift you into the air, making you vulnerable. Use this to your advantage for plunging attacks or dodge to land safely.
Strategy: 
•Anemo Characters: Characters like Venti, Sucrose, Jean, or Traveler (Anemo) can disrupt its attacks and increase your elemental mastery.
•Crowd Control: Use characters like Venti or Sucrose to crowd control or push the Hypostasis into corners to limit its mobility.
•Elemental Reactions: Use Electro with Anemo for Swirl, which can increase elemental damage. Characters like Fischl or Razor can be effective.
•DPS and Support: Balance your team with a strong DPS character for damage when the core is exposed and supports like Bennett for healing or Zhongli for shields.
•Mobility: Keep moving to avoid its wind-based attacks. The environment in Stormterror's Lair can be used for dodging or repositioning.
•Timing Your Bursts: Save your most damaging abilities for when the core is exposed or to break the shield quickly.
Recommended Team Composition:
•Anemo DPS: Venti or Sucrose for crowd control and elemental mastery boost.
•Main DPS: Any strong DPS like Diluc, Keqing, or Eula can excel when the core is exposed.
•Support: Jean or Kaedehara Kazuha for healing, elemental support, and crowd control.
•Flex: Fischl for Electro reactions, or Diona for shields and healing.
Tips: 
•Use the Environment: The cave has ledges and corners that can be used to dodge or hide from attacks.
•Elemental Mastery: Since you'll be dealing with Swirl reactions often, characters with high Elemental Mastery can significantly boost your damage output.
•Shield Management: Characters like Zhongli can provide shields that are very effective against its wind attacks.
•Positioning: Stay at a mid-range to avoid close-range attacks while being able to dodge the wind blades.
•Energy Recharge: Bringing characters with good energy recharge can help you keep your key abilities up, especially for breaking shields or dealing burst damage.
Rewards:
•Vayuda Turquoise (Sliver, Fragment, Chunk, Gemstone): These are the main ascension materials for Anemo characters like Venti, Jean, Sucrose, Xiao, and others.
•Hurricane Seed: A unique drop specifically for ascending Anemo characters.
•Artifacts: You might receive artifacts from sets like Berserker, Instructor, The Exile, Gladiator's Finale, or Wanderer's Troupe (especially useful for Anemo characters due to its elemental mastery boost).
•Companionship EXP and Mora: Useful for increasing friendship levels with characters and for general in-game currency.
General Tips:
•Focus on Elemental Mastery: Since Swirl reactions increase based on Elemental Mastery, equipping artifacts or characters with high EM can significantly boost your overall damage.
•Dodge Patterns: The Anemo Hypostasis has predictable attack patterns. Learning these can help in dodging more effectively, reducing the damage you take.
•Shield Breaking: While any attack can break its shield, using Anemo or physical damage from claymore users can be slightly faster.
•Team Synergy: Utilize characters whose abilities synergize well together. For instance, Jean can heal and provide Anemo support, while someone like Fischl can trigger Swirl reactions with her Electro damage.
•Artifact Sets: Prioritize sets like Wanderer's Troupe for Anemo characters, especially if they have high Elemental Mastery rolls, as they enhance elemental damage.
•Food and Potions: Bring food or use anemo resistance potions if available to reduce incoming damage.
•Co-op: If the fight is too challenging alone, consider co-op. Multiple players can make the fight easier by spreading out the Hypostasis's attention and combining elemental effects.
•Strategy Adaptation: If you're having trouble, adapt your strategy. Perhaps focus more on crowd control, or bring a character with a stronger burst for when the core is exposed.
Fighting the Anemo Hypostasis requires a balance of mobility, elemental reactions, and strategic timing. With the right preparation and team composition, you'll be able to gather the necessary materials for your Anemo characters efficiently. Remember, practice makes perfect, and each encounter with a boss can teach you new ways to approach the fight.
