The Astrolabos Chapter tells Mona’s story in Genshin Impact, and in this guide we’ll teach you how to complete it.
Mona’s story quest is not a temporary event like some of the other quest events in Genshin Impact, but there are some requirements you must meet and some challenges that are difficult to overcome.
Genshin Impact – Astrolabos Chapter Guide

You’ll need to meet a few prerequisites to start Mona’s story quest.
- Reach Adventure Level 38 or higher.
- Complete the mission Noctua: Act 1 – The Dark Hero’s Alibi.
- Obtain a story key to unlock the quest.
After spending the key, head to the Liyue Port entrance to find Mona and trigger a cutscene. The quest will begin as soon as you agree to form a team.
The Astrolabos Chapter starts off easy, tasking you with taking a simple detour to allow Mona to say goodbye to the innkeeper on Mt. Tianheng. The man you are looking for is Mr. Zhu, who you’ll find outside the deserted inn.
After learning of your predicament and receiving a very tempting help offer, you are given your first real mission to retrieve Mr. Zhu. Here is the list of goals that follow.
- Follow the marked point.
- Set the elementary bait.
- Defeat the slimes.
- Collect the ring.
- Return the ring to Mr. Zhu.
The monsters are easily defeated, and overall it’s a pretty straightforward start to a quest. Mona will be impressed, and after a bit of Mr. Zhu, she will accept the bounty on his behalf.
Go to the teleport and find Mona at the Wangshu Inn to start the next cutscene. Feeling sorry for Mona, your next task is to ask to use the kitchen to make her a proper meal.
You will need to make the Golden Crab dish, the recipe of which you will receive from the innkeeper.
- 5 Bird Eggs, which you can find worldwide or buy from Good Hunter.
- 5 wheat flour.
- 4 Crabs you need to collect.
- 2 Salt you can buy at general stores
Once you have all of the above, cook and present to Mona. After letting out a few compliments, she’ll be ready to continue the quest.
Head to Bishui Plain in Liyue and head to the next waypoint to start the next cutscene, ending in a battle with four bandits. With Mona’s help, they pose no threat.
Back on the way to Mondstadt, go to Starfell Valley and run to the bridge. Another long scene will play – at the end, you’ll need to go after Klee to retrieve the box for Mona.
You can run or teleport to the Statue of Seven on Galesong Hill to catch up quickly. When you arrive, it becomes clear that some Dendro Slimes have invaded the spot where Klee buried the box.
Dendro are tricky enemies, nearly impossible to defeat when their defenses are intact. Here’s what you need to know and the best prerequisites for dealing with them:
- Dendro remains underground and only emerges when your back is turned.
- A Pyro-based character is by far the more tactical approach.
- Force Dendro to remain above ground by landing on the ground. This leaves them extremely vulnerable to attack.
Once exposed, Dendro poses little threat, so take them out and retrieve the box.
Return to the bridge with Klee to trigger a cutscene with Mona, where you discover that the box was empty the entire time and that Mona already had what she was looking for. In the end, Mona decides to stay in Mondstadt for a while, but you’ll have to go see Katheryne from the Adventurer’s Guild to see if Mona can stay there.
This is another simple task, talk to Katheryne at the table. She explains that there is a magically sealed laboratory in Mondstadt that no one else is interested in breaking. If Mona manages to break the seal, she can stay there.
The house is just around the corner, marked on your map, with a glowing magic seal on the door. Investigate the lab to start the final cutscene.
