Here's a detailed guide for the "Hurdle" quest in Genshin Impact, which is part of Prologue: Act 3 - Song of the Dragon and Freedom:
Prerequisites:
•Adventure Rank: You must be at least Adventure Rank 18.
•Previous Quest: You need to have completed "Abyss Mage," the previous part of this Act.
Quest Start:
•Location: The quest begins at the entrance to Stormterror's Lair. If you're not already there, you can fast-travel to the Cecilia Garden domain and move west towards the lair.
Quest Steps: 
1. Travel to Stormterror's Lair:
1.Navigate towards Stormterror's Lair. The path leads north from Mondstadt. Use the waypoint near Cecilia Garden for quicker access.
2. Encounter and Defeat Enemies at the Entrance:
2.Upon reaching the entrance, you'll be blocked by a group of enemies:
▪Wooden Shieldwall Mitachurl: This enemy has a wooden shield which is weak to Pyro, so bring a Pyro character like Amber or Diluc.
▪Anemo Samachurl: This enemy can create wind currents; deal with him quickly to prevent crowd control.
▪Hilichurl Grenadier: Throws explosive barrels; prioritize taking him down to reduce the risk of area damage.
3.Strategy: 
▪Start by targeting the Anemo Samachurl to avoid wind control issues.
▪Next, focus on the Mitachurl. Use Pyro attacks to destroy his shield, then attack him directly.
▪Lastly, handle the Grenadier to prevent area damage.
3. Cutscene and Dispelling the Wind Barrier:
4.After defeating the enemies, a cutscene will trigger where Venti uses his powers to disperse the wind barrier blocking the entrance to Stormterror's Lair. This is purely cinematic; you won't need to do anything here.
4. Enter Stormterror's Lair:
5.Once the barrier is down, proceed into the lair to continue the storyline.
1.Key Points:
▪Team Composition: Having at least one Pyro character is crucial due to the Wooden Shieldwall Mitachurl. An Anemo character can help control the battle by grouping enemies or using environmental effects.
▪Elemental Reactions: Use reactions like Overload or Vaporize to deal extra damage, especially against the shield.
▪Healing and Shields: Bring a healer or a character who can create shields (like Noelle or Diona) to manage incoming damage, especially from the Grenadier's bombs.
