Steller Shimmer is yet another Honkai Star Rail event that pits you against some tough enemies with some unique buffs to your team. To take advantage of how these events work, you want to build the best possible team for each event level.
A complete guide to the Steller Shimmer in Honkai Star Rail
The basic idea behind this event is that Explorer Grumpy from the space station has asked you to help with some kind of experiment. You have to clear eight challenges, and one new one unlocks every day. This article will be updated as new challenges drop in this event.
Each of these stages has two separate events; one is called Dwarf Star, which is like a tutorial for you to test out the Trail characters and see in real time how the buffs will work, and the other is called Supergiant Star, which is the actual main event of each stage. . You must first complete the Dwarf Star to reach the Supergiant Star.
Day 1: Vanguard Breaker
Vanguard Breaker is all about weak breaking enemies. The test characters are Firefly and Harmony Trailblazer, which are two characters focused on break. The best two characters to add to this team are Ruan Mei and Gallagher, as you will need Support and Support. If you lack any of these characters, you can sub in any Sustain for Gallagher. You can also replace Ruan Mei with a well-built Himeko or Asta (Asta is Skill Point-heavy, but the team will generate SP well enough to keep her up).
Once the battle starts, you’ll need to push Firefly into Burning mode, then aim for its target to break creatures one by one. The Trial Firefly has a 282% break effect, so you should have no problem smashing the break bars even without your own Firefly. Use Ruan Mei’s Skill if you have her, and Harmony Trailblazer’s Ultimate before Firefly’s Combustion. If you can’t break any of the creatures on the stage in the first go, use Gallagher to deal additional fire damage, as all of these enemies are weak to fire. Try not to break enemies with Harmony Trailblazer to make sure Firefly gets all those sweet, sweet extra turns.
Pick your targets in a way that prioritizes generating as many additional turns with a weak break. This will be instead of breaking multiple enemies at once, which will only give one more turn. If you have the choice between breaking three enemies or breaking one depending on which enemy you target, only break one at a time.
The hardest part of the waves will be the battles against Argenti. He will summon an attachment called The Shield, which will create a shield to block damage on Argenti. Prioritize killing The Shields first, then use a basic attack or clip Argenti with a different attack to remove The Shield’s sand from Argenti before outsmarting him. Argenti will have another attachment called Speartip, and this thing will deal a pretty big AOE of physical break damage around it, so target that attachment last.
Day 2: Cycle of Suffering
Day 2 gives you Acheron and Silver Wolf a try; you will need to add one Sustain unit and one Nihility unit. Without a third Nihility unit, Acheron will not be able to properly work her magic. I chose to use Kafka because my Kafka is pretty strong, but you could sub in any Nihility unit you have like Black Swan, Guinaifen or even Pella. Kafka is also great because she has cleft and everything you fight is already weak to lightning.
As for your Continue, Aventurine is the best choice because he does the right kind of damage. However, if you don’t have him, Gallagher is a good choice as he deals fire damage and also issues debuffs. If you don’t have Aventurine or Gallagher, you can use whatever Sustain you have available, as all the others are pretty much the same.
In this round of enemies, you’ll notice that all the enemies share one HP pool, which makes Bronya a tough final boss that you’ll have to take down twice. In the non-Bronya fights, focus on a single enemy, stacking Ultimate Vulnerability on top of them as much as possible. Also, keep Aventurine’s shields up at all times. You’ll want to use Acheron’s Ultimate as often as possible.
For those who don’t know how Acheron works, you’ll see a number next to a flower under her nameplate in the lower left part of the screen. She needs 10 of these flowers to make her Ultimate turn, and she can hold up to 30 of these at once. Once she hits three held Ultimates, you’ll lose any more flowers, so be sure to use her Ultimate before you start running out of flower drops.
When Bronya gets up, you’ll want to focus on her. Since Bronya can clear her adds of damage but not herself, and you can’t break her unless her adds are dead but they all share the same pool of HP, there’s no reason to target anyone but Bronya in these fights.
Day 3: Surprise Party
Surprise Party is a much simpler round of battles. You’ll have Robin and Topaz, and you want to focus on follow-ups. The Giftbox, which is the main buff of Surprise Party, all enemies will be weak broken, leading to follow-ups of all characters that can follow. The Trail Robin and Topaz are both pretty well built, so you should be able to use them without worrying about not getting all the rewards. Good additions to this team are Sustain, and the best follow up Sustain is Aventurine. If you don’t have him, you can submit in Gallagher or Bailu. Fu Xuan is also okay because she can allow you to avoid Freeze.
For the fourth in the party, you should use Himeko. She deals fire damage, and the Gift Box will trigger her follow-ups. She works best if she has her signature cone of light. If you want to use your Dr. Ratio, you’ll need to make sure your Aventurine and Topaz have at least E1 or S1 between them. If you don’t, you won’t have enough debuffs to trigger Ratio’s follow-up.
Now that you have a team, you need to prioritize every follow up you can get. Use Robin’s Ultimate in battle to manipulate the turn order so you can take as many turns as possible while Giftbox is active, which will increase the number of follow ups you will receive.
Day 4: Skin of Their Teeth
Skin of Their Teeth gives you Dan Heng – Imbibitor Lunae and Sparkle. For this team, you won’t need to Continue a unit, because the enemies are designed to kill your characters every turn. So instead, you want to pick those that have great Ultimates to either boost Dan Heung or deal damage on their own. Great teammates would be Argenti, Bronya, Tingyun or Hanya. I chose the Dan Heng, Sparkle, Tingyun and Hanya Road. Acheron is a bad choice for this one, mainly because she doesn’t use energy. The most important things to do in this battle is not to waste energy and make sure you have Sparkle and Dan Heng in the center spots so they take the most hits.
The first round is between your team and Guardian Shadow and Silvermane Lieutenant. You want to inflict damage on them equally, which will force them both into their revenge modes. The second round has a fire enemy and an ice enemy. Focus on the fire enemy first; the ice enemy has a deathly AOE that is guaranteed to kill your entire team so you have energy for the boss fight.
The boss, which is Memory Zone Meme, will cast Go Into That Good Night on his second turn, which will create a cage out of the next two characters to do anything after it’s cast. Make sure you don’t get Dan Heng trapped in the Meme’s cage as it will brick your ability to deal damage and get your characters out of those cages.
Day 5: Fatal Weakness
It’s breakout effect 2.0, but this time, it’s tailored around Boothill over Firefly. Since this doesn’t specify a Super Break, Firefly can be used here, but Trial Boothill will be best despite his low break effectiveness percentage. Feel free to run your own Boothill if you have a better build than the Provo. Ruan Mei is also great here, and her Trial is pretty well put together.
You need Sustain to add to this team. For your Sustain, the best choice is Gallagher as he is also a Break Effect character, but any Sustain can be used here. Aventurine is a good choice due to the enemies being weak to Imagination damage. But anyone will work here in a pinch. As for the fourth, an E4-or-higher Harmony Trailblazer is a great choice. You could also use Bronya or Sparkle to give Boothill more turns. If you don’t have any of these, Xueyi is also a good choice for a fourth.
To win, you want to build a Pocket Trickshot for Boothill by killing and breaking enemies. He will use them when in Standoff mode to deal additional Break damage to enemies. You will need to take out Geopardon, so make sure Ruan Mei’s skill is used every three turns to keep everyone pumped up for this challenging battle.
