To take on Chassanion, completion of The Search in the Algae Sea quest is a prerequisite.
Locating Chassanion in Genshin Impact

Chassanion, the recently unveiled local legend in the 4.2 update of Genshin Impact, awaits on the bottom floor of the Tower of Ipsissimus. To engage with this boss monster and claim enticing rewards, follow these steps:
- Utilize the Teleport Waypoint near the Tower of Ipsissimus to reach the underwater location.
- Dive underwater from the waypoint to access the lower floor.
- Once on the floor, enter the central chamber and select “Enter” to descend further.
- Navigate through the passage, descend the staircase, and reach the bottom-most floor where Chassanion lurks.
Tips for Defeating Chassanion

To conquer Chassanion, players need to harness the abilities of the Xenochromatic Ball Octopus. Locate one nearby and hold the normal attack button to target its ability. Chassanion attacks with bubbles that pursue and explode on contact. Use the Ball Octopus’s ability to push these bubbles back towards the monster. Victory lies in hitting Chassanion with its own bubbles, so repeat the process strategically to secure your win.
Achievements and Rewards

Following the defeat of Chassanion, you will earn the “Chassanion” achievement, granting you five Primogems. Additionally, you’ll receive a Precious Chest and one Mysterious Xenochromatic Crystal for your successful encounter with this local legend.
