Important takeaways

In Honkai: Star Rail, team building is everything, and character synergies can make all the difference in achieving your perfect 36-star Memory of Chaos run. No matter how perfect your relic scrolls may be, your characters can only go so far on their own.

Combining complementary abilities not only enhances your team's skills, but also opens up unique playstyles and strategic advantages. From powerful combos that unleash devastating damage to support pairs that make your team nearly unbreakable, here are the best character synergies to maximize your success in Honkai: Star Rail.

8 Jiaoqiu and Acheron

Jiaoqiu and Acheron were made for each other, forming a perfect synergy rooted in debuff stacking. Jiaoqiu's 'Ashen Roast' stacks amplify enemy damage, which feeds perfectly into Acheron's 'Slashed Dream' stacks, which are generated when a debuff is applied. When Acheron reaches nine stacks, her Ultimate unleashes devastating AoE attacks.

This combo is especially useful in multi-wave battles or when facing groups, where Jiaoqiu applies Ashen Roast to all enemies and Acheron's Ultimate cleaves them all. For best results, pair them with additional Nihility units such as Silver Wolf or Pela. This will activate Acheron's talent and also keep her Ultimate stack constantly building, making this synergy one of the best DPS picks in the game.

7 Feixiao and Robin

Robin's fans for follow-up attacks are invaluable to Feixiao, who uses these boosts to constantly knock down enemies with a flood of powerful follow-ups. Robin's support gives Feixiao increased attack rate and improved hitting power, making this duo the top choice for any follow-up focused team.

This setup is especially powerful in single target battles where Feixiao's devastating attacks can take full advantage of Robin's buffs to eliminate bosses quickly. If you're a fan of the follow-up team archetype, Robin's ability to boost Feixiao's attacks makes this synergy your best choice.

6 Bronya and Jingliu

Bronya's crit, speed buff, and most importantly, action-promoting skill, maximize Jingliu's potential to activate her talent in a single turn, allowing her to deal devastating amounts of damage in rapid succession. While the combo is skill point intensive, Bronya's Action Advance allows Jingliu to potentially attack three times in one turn without interruption, making the duo especially strong when maximizing Jingliu's Crit potential.

For players who enjoy flashy damage, this duo delivers a high-risk, high-reward playstyle that thrives in any hyper-carry team scenario.

5 Aventurine and Dr Ratio

Dr. Ratio's single-target skills get a defensive boost from Aventurine's shields, which protect him as he cycles through follow-up attacks. Aventurine also boosts Effect RES, allowing Dr. Ratio focus on attacking without sacrificing survivability.

Because Dr. Ratio's follow-up attacks are triggered by his talent, which is more consistent when enemies are debuffed, giving Aventurine additional synergy through his Ultimate's debuff application. The synergy here is a strong mix of offense and defense, making Dr. Ratio can dish out reliable damage alongside Aventurine's own follow-up attacks.

4 Sparkle And Imbibitor Lunae

Sparkle's buffs accelerate Imbibitor Lunae's powerful attacks, providing action progress and crit boosts. These benefits are good in themselves. However, the most important benefit of Sparkle is that she increases your total available skill points. Sparkle's changes to the skill point economy make her a perfect partner, allowing Lunae to dish out maximum DPS without losing damage potential due to a lack of skill points.

Imbibitor Lunae's strength lies in his ability to deal consistent, concentrated damage, but he often wants some sort of action progression to keep up the pressure. This combination makes up for his weaknesses. Together, Lunae and Sparkle form an aggressive pair suitable for almost any content in the game, especially against Imaginary weak enemies.

3 Kafka and the Black Swan

Kafka is the queen of DOT and her abilities are best utilized in conjunction with Black Swan's “Arcana” debuffs, which reduce enemy resistance and make DoT effects even more deadly. Black Swan can quickly build stacks of her Arcana on groups of enemies and set them up for Kakfa's Ultimate. You can think of Black Swan as a mine deployer, and Kafka is the trigger that can set off the DOT explosion.

This pair feels like they were made for each other, as Black Swan's abilities work perfectly with Kafka. This setup thrives particularly well in multi-enemy content, creating a cycle of DOT applications and detonations that can easily blast through waves of enemies.

2 Harmony Trailblazer And Firefly

Firefly is a specialized Break Damage Dealer who thrives in lineups that boost her “Burn” condition. This makes the Harmony Trailblazer the perfect ally, as they provide boosts to the Break Effect and above all provide the powerful Super Break effect with their Ultimate. Since Firefly's enhanced skill and basic attack can apply Fire Weakness Break, this allows her to both break and deal massive Super Break damage to any enemy with a toughness bar.

This duo excels in scenarios where Firefly can make full use of BE mechanics (which is the most content). Ruan Mei can further support this team with all-type Resistance Penetration and increases the effectiveness of Weakness Break, making her another great addition to this break-centric strategy.

1 Ruan Mei and Boothill

Boothill is your primary Physical Break DPS and he synergizes incredibly well with Ruan Mei, whose skills boost allies' Break Efficiency and RES PEN. Boothill's Break mechanic revolves around his improved Basic Attack, which can deal Break Damage even after an enemy's Toughness has been depleted. Ruan Mei's RES PEN boost and break extension abilities make Boothill's break hits even stronger, maximizing his DPS potential when enemies are in a broken state.

With Ruan Mei's boosts, Boothill's breaking potential accelerates dramatically, which is especially important in boss fights where a broken toughness bar plays a crucial role in Boothill's damage. For optimal support, adding a Harmony Trailblazer or Bronya can greatly help Boothill's gameplan, giving him more frequent turns to take advantage of Ruan Mei's Break Effect buffs.
