Steller Shimmer is another Honkai Star Rail event that pits you against a number of challenging enemies with some unique buffs for your team. To take advantage of how these events work, you'll want to build the best possible team for each event level.

The basic idea behind this event is that Researcher Grumpy from the space station has asked you to help with some kind of experiment. You have to complete eight challenges, with a new one unlocked every day. This article will be updated as new challenges appear in this event.

Each of these stages has two separate events; one is called Dwarf Star, which is a tutorial of sorts to try out the Trail characters and see how the buffs work out in real time, and the other is called Supergiant Star, which is the actual main event of each stage. You have to complete the Dwarf Star first to get to the Supergiant Star.

Vanguard Breaker is all about weak enemies. The trial characters are Firefly and Harmony Trailblazer, two characters that focus on breaking. The best two characters to add to this team are Ruan Mei and Gallagher, since you will need a Sustain and a Support. If you are missing either of these characters, you can replace any Sustain with Gallagher. You can also replace Ruan Mei with a well-built Himeko or Asta (Asta is heavy on Skill Points, but the team will generate SP well enough to keep her going).
