The first elixir crucible can be seen as soon as you are at the bottom platform. Investigate it to turn it off! |

The second crucible is just ahead of the first one. You don't need to press any buttons as you pass it by because it's already closed! |

Dan Shu transforms to become The Ascended Boss Enemy! To defeat her, you must have Physical, Ice, or Lightning characters with you. You must also bring a healer with you to avoid gaining too much damage from her Prana-Siphon skill.
| Quest Walkthrough | |
|---|---|
| 1 | As Dan Heng, you arrive at the Alchemy Commission with Luocha and Sushang. The Trailblazer messages him. However, Dan Heng is unable to send any messages. |
| 2 | Leave the Healer's Market on your own by following the quest markers. You can also do an optional objective to talk to the characters around the area before you leave. |
| 3 | Follow through the quest markers to find out where the Trailblazer and the others are. |
| 4 | As you go down, you can interact with the past echoes of the Vidyadhara. These will also be markers of the direction toward a starskiff! |

| 6 | As soon as Dan Heng sets food in the Scalegorge Waterscape, you will encounter Blade and Kafka. Yanqing then appears and fights with Blade in a cutscene. Blade makes Dan Heng show his true form as the Imbibitor Lunae. |
| 7 | Another fight commences now with Blade and Dan Heng as story characters against Yanqing. Note: Blade and Dan Heng are trial characters during this time. You can only fight Yanqing using them. |
| 8 | Kafka stops all three from fighting, and Jing Yuan appears to talk with all characters there. After that, you go to the Lunarescent Depths with Jing Yuan. |
| Quest Walkthrough | |
|---|---|
| 1 | Go to the Dragonvista Rain Hall to meet up with the rest of Astral Express Crew. |

| 4 | A cutscene will start as Dan Heng opes the path toward the root of the Ambrosial Arbor. After that, the mission is complete! |
