The in-battle notification indicates you have met an achievement's conditions for that specific fight. To officially register the achievement to your account, you must meet the criteria of the achievement.
If you have not received your reward after meeting an achievement's conditions, please check the following:
- Ensure the method you used to unlock the achievement was correct.
- Confirm that all prerequisites and conditions have been met.
For more detailed strategies, we recommend discussing with other Trailblazers or consulting guides in the Honkai: Star Rail community.
