Here's a detailed guide on "A Long Shot", part of the Archon Quest Prologue in Genshin Impact. Remember, this guide reflects the general gameplay as of this writing. If there have been recent changes or updates to Genshin Impact specifics like rewards or exact quest mechanics might differ.
Unlocking the Quest 
1.Prerequisites: You must have completed "Calm Before the Storm," the previous quest in the Prologue: Act III - Song of the Dragon and Freedom.
2.Adventure Rank: Around AR 18-20, as this continues the narrative from where the previous quest left off.
Quest Walkthrough
1.Aftermath of the Previous Encounter: The quest might start with a debrief or a strategy meeting in Mondstadt, discussing the next steps after your initial encounter with Dvalin (Stormterror).
2.Seek Out Dvalin: You'll likely be tasked with confronting Dvalin once more, but this time with a clear plan or new weapon/strategy to deal with his corruption or to reach out to him without causing harm.
3.Gathering Allies or Items: This phase might involve fetching special items or convincing other characters to assist in the battle. This could include:
4.Speaking with Diluc at his winery or the tavern, perhaps to gain his support or acquire something from him.
5.Possibly meeting with Lisa or another scholar for magical or elemental assistance.
6.Travel to Dvalin's Lair: Head towards Stormterror's Lair again, this time with your preparations complete. There could be puzzles or enemies along the way as part of a buildup to the final confrontation.
7.The Final Battle with Dvalin: Ascent: You might need to ascend or glide up to where Dvalin is, using wind currents enhanced by Venti or other means.
8.Combat Phases: The battle with Dvalin would likely have multiple phases:
9.Phase 1: Initial engagement, where you dodge attacks and try to weaken Dvalin or remove sources of his corruption.
10.Phase 2: Possibly a phase where you're inside his domain or on his back, attacking weak points or purifying corruption nodes.
11.Phase 3: The climax where Dvalin might be more vulnerable, allowing for significant damage or a moment to communicate with or purify him.
12.Purification and Resolution: After successfully dealing with Dvalin's corruption, there'll be a scene where either Dvalin is freed from his torment or where you learn more about the Abyss Order's role in his corruption.
13.Return to Mondstadt: Conclude the quest by returning to Mondstadt, reporting back to Jean or Venti about the outcome. This might involve discussions on what to do next regarding the Abyss Order or celebrating the liberation of Dvalin.
