Follow our step-by-step guide for Genshin Impact's 'Act IV: Where Ancient Stars Align' quest. Uncover clues, battle foes, and destroy the meteorite core to progress Fischl's story.

Alright, let's dive into Act IV of the Unreconciled Stars event, titled "Where Ancient Stars Align." This is where things really start to wrap up, especially for Fischl's story. You'll need to be Adventure Rank 20 or higher to even start this one.

Walkthrough
  1. 1
    First up, you'll want to head to the East Windrise teleport waypoint. From there, make your way over to Mona and chat with her about how her scrying is going.
  2. 2
    After that, it's time to head back to Mondstadt. Find Katheryne at the Adventure Guild. She'll give you a hint that the library might hold the answers you're looking for.
  3. 3
    So, make your way to the Knights of Favonius Headquarters and pop into Lisa’s library – it's the door on your right.
  4. 4
    Once inside, head over to the big book open on Lisa’s desk. Check the index there; it’ll give you a general idea of where to find the book you need.
  5. 5
    Paimon will mention the book is likely in the northwest corner of the top floor. Go there, interact with the glowing spot on the bookshelves, and you'll find “Of Mountains and Seas,” the book authored by Leonard.
  • Got the book? Awesome! Now, head back to the East Windrise teleport waypoint and tell Mona what you found. She'll then point you towards Murk Reef.
  • To get to Musk Reef, your best bet is to use the Spiral Abyss waypoint if you've unlocked it. If not, you'll need to go to Cape Oath. Look for a wormhole there. Beneath it, you'll see three Seelie statues. Guide a Seelie to each statue to activate a wind spout that will carry you up to Musk Reef.
  • Once you arrive at Musk Reef and the cutscene plays out, you'll find yourself in control of Mona. Your task here is to defeat two Fatui Skirmishers. Don't worry too much; Mona's pretty capable. Her normal attack combo is swift, and charging it up can deal decent damage. Her Elemental Skill is great too – it summons a phantom that draws enemy aggro and deals a bit of damage.
  • With the Fatui dealt with, approach the meteorite. Another scene will play out, and upon its conclusion, the quest will be complete!
    • Tips
    • When fighting the Fatui Skirmishers as Mona, remember to use her Elemental Skill to taunt them. This gives you breathing room to charge up your attacks or reposition.
    • If you're having trouble finding the meteorite core on Musk Reef, Mona's Mirror Reflection of Doom skill can help illuminate the area or draw attention away from you.
