Support characters focus on providing valuable utilities like buffing, debuffing, healing, or shielding, ensuring your team has the tools to thrive in any battle. Selecting the right support to complement your team’s playstyle can make even the toughest content more manageable.

In this guide, we’ll highlight the best support characters in Honkai Star Rail, showcasing their unique abilities and why they’re essential for success. Let’s dive in and discover which supports can take your gameplay to the next level!

#10: Topaz and Numby

• Rarity: Five-Star
• Type: Fire
• Path: The Hunt
• Synergy: Best with follow-up attack-focused characters (e.g., Jing Yuan, Clara, Dr. Ratio, Himeko, Herta)

Topaz and Numby are a unique addition to Honkai: Star Rail as the first duo unit, bringing an innovative playstyle centered around follow-up attacks. Once their key Traces are unlocked, nearly every part of their kit revolves around follow-up mechanics, with Numby stealing the spotlight during their Skill and Ultimate.

Although classified as a Hunt character with impressive single-target damage potential, Topaz and Numby truly shine as support for teams focused on follow-up attacks. Their Skill applies a debuff to an enemy that increases the damage they take from follow-up attacks by up to 55%, significantly boosting the output of allies like Jing Yuan and Clara.

This makes them a valuable asset in specialized team compositions where follow-up attacks are the cornerstone of your strategy. Their unique synergy ensures they stand out as an excellent support option in the right setup.

#9: Pela

• Rarity: Four-Star
• Type: Ice
• Path: The Nihility
• Best Synergy: Works well with most characters, especially Dr. Ratio, Jingliu, and Yanqing

Though Pela may be a four-star character, she holds her ground as a valuable support in many team compositions thanks to her straightforward yet impactful abilities. Her primary role is to decrease enemy DEF, boosting your team’s overall damage output, while also increasing Effect Hit Rate for teammates and occasionally dispelling enemy buffs.

Pela’s Ultimate is a game-changer, as it applies a DEF reduction to all enemies on the battlefield, making it especially effective in multi-enemy encounters. Additionally, Pela doesn’t rely heavily on using her Skill, allowing her to conserve Skill Points for other team members. A SPD-focused build further enhances her ability to generate Skill Points efficiently, ensuring your team maintains momentum in battle.

With her utility, Pela proves that rarity isn’t everything. Her versatile kit makes her a staple support option, particularly in teams that benefit from debuff-focused strategies.

#8: Luocha

• Rarity: Five-Star
• Type: Imaginary
• Path: The Abundance
• Best Synergy: Ideal for teams with Blade or Skill Point-reliant characters

Luocha is a standout support in Honkai: Star Rail, renowned for his ability to restore large amounts of HP and provide critical utility to his team. Beyond his exceptional healing, Luocha offers debuff cleansing for allies and can even remove buffs from multiple enemies, adding versatility to his role.

One of his most unique features is his ability to deploy a healing field, which automatically restores HP to teammates whenever they perform an attack. This ensures consistent healing during combat without interrupting your offensive momentum. What truly sets Luocha apart, however, is his ability to function without consuming Skill Points. His Skill automatically activates when an ally’s HP drops below 50%, ensuring clutch saves while conserving resources for the rest of your team.

With his unparalleled healing and no-cost utility, Luocha is a must-have support for teams that rely heavily on Skill Points or need sustained survivability in challenging encounters.

#7: Tingyun

• Rarity: Four-Star
• Type: Lightning
• Path: The Harmony
• Best Synergy: Ideal for ATK-scaling characters reliant on their Ultimate, such as Jing Yuan, Dan Heng: Imbibitor Lunae, Jingliu, and Argenti

Despite being a four-star character, Tingyun remains one of the most reliable and versatile supports in Honkai: Star Rail, even with the release of newer five-star units. Her kit is simple yet highly effective, focusing on boosting the performance of her allies.

Tingyun’s Skill provides a powerful ATK buff to a single ally, which scales off her own ATK, making her an excellent choice for teams centered around strong damage dealers. Her Ultimate further enhances her utility by offering a DMG Bonus to a target ally and restoring Energy, enabling them to unleash their Ultimate more frequently.

Additionally, Tingyun is efficient in managing Skill Points, as her ATK buff lasts for three turns, minimizing the need to frequently recast her Skill. This allows her to amplify your team’s output without being a drain on resources.

With her ability to enhance both damage and Energy regeneration, Tingyun is a valuable asset to any team composition, especially those built around Ultimate-dependent DPS characters.

#6: Silver Wolf

• Rarity: Five-Star
• Type: Quantum
• Path: The Nihility
• Best Synergy: Works well with any team, especially with Seele, Qingque, and Dr. Ratio

The genius hacker of the Stellaron Hunters, Silver Wolf, brings a unique and game-changing mechanic to Honkai: Star Rail. She can implant a Weakness on enemies that matches the element of one of your team members, enabling your characters to exploit elemental Weaknesses even when the enemies don’t naturally have them. This makes her a versatile asset in almost any composition.

Her Ultimate is a powerful debuff tool, reducing the target’s DEF by up to 48% for three turns, significantly boosting your team’s damage potential. Additionally, all her attacks have a chance to apply a random debuff to enemies, each with independent durations:
• ATK Reduction: Lowers enemy ATK by 11%.
• DEF Reduction: Decreases enemy DEF by 8.8%.
• SPD Reduction: Slows enemy SPD by 6.6%.

Silver Wolf’s ability to manipulate enemy weaknesses and stack debuffs makes her a standout support for both single-target and multi-target encounters. With her tactical debuffing and synergy with damage dealers, she excels in empowering your team to dominate even the toughest battles.

#5: Fu Xuan

• Rarity: Five-Star
• Type: Quantum
• Path: The Preservation
• Best Synergy: Effective with any team, especially Blade and Jing Yuan

Fu Xuan redefines the role of Preservation characters in Honkai: Star Rail by foregoing traditional shielding in favor of damage mitigation. Unlike her counterparts, she protects her team by drastically reducing the damage they take, enabling even fragile allies to withstand powerful attacks with ease.

Her Skill creates a field that significantly reduces incoming damage for all allies while redirecting a portion of that damage to herself. This unique mechanic not only keeps her teammates safe but also leverages her resilience to sustain through prolonged battles. Additionally, Fu Xuan has a built-in survival mechanism—when her HP drops below 50%, she can automatically heal herself to near full health under specific conditions, ensuring her durability and the continued protection of her team.

Fu Xuan’s blend of damage mitigation and self-sustain makes her a remarkable support, particularly for teams with glass-cannon characters or those facing high-damage scenarios. Her ability to turn potential defeats into victories makes her a cornerstone of any solid team composition.

#4: Huohuo

• Rarity: Five-Star
• Type: Wind
• Path: The Abundance
• Best Synergy: Works well with any team, especially characters that scale with ATK and rely on their Ultimate

Huohuo, the timid (and endearing) Judge of the Ten-Lords Commission, brings exceptional utility as both a healer and semi-support in Honkai: Star Rail. Her passive healing capabilities make her an ideal sustainer for long battles, while her abilities provide critical debuff removal and team-wide buffs.

Upon using her Skill, Huohuo performs a multi-layered action:
• Dispels one debuff from the target ally and restores their HP.
• Simultaneously heals allies adjacent to the target, offering additional sustain.
• Gains two stacks, which gradually decrease over time. While these stacks are active, Huohuo heals and removes debuffs from allies at the start of their turn or whenever they use their Ultimate.

Her Ultimate adds another layer to her versatility. It not only grants a team-wide ATK buff but also regenerates Energy for all allies, enhancing their ability to unleash Ultimates more frequently.

Huohuo’s combination of healing, debuff cleansing, and offensive support makes her an indispensable asset for any team, particularly those built around ATK-scaling units or Ultimate-reliant strategies. Her balanced toolkit ensures that allies stay healthy, debuff-free, and primed for high-impact moves.

#3: Ruan Mei

• Rarity: Five-Star
• Type: Ice
• Path: The Harmony
• Best Synergy: Works effectively with any team composition

As the first limited Harmony Path character in Honkai: Star Rail, Ruan Mei sets a high standard for support units. Her kit is packed with powerful buffs and debuffs that elevate her team’s performance across multiple aspects of combat. She doesn’t just offer one or two enhancements—her abilities provide a wide range of benefits:
• 35.3% DMG Bonus to allies.
• 50% Weakness Break Efficiency, making it easier to deplete enemy Toughness Bars.
• 27% All-Type RES Penetration, increasing overall damage dealt to enemies.
• Weakness Break Management: Extends the duration of enemy Weakness Breaks and delays their recovery actions.
• Ice Break DMG: Automatically deals Ice Break damage anytime an ally breaks an enemy’s Toughness Bar (via Talent).
• 10.4% SPD Increase to allies, improving turn efficiency.
• In the Simulated Universe, her Technique allows any character to attack an enemy’s Weakness, regardless of their Type.

Ruan Mei’s comprehensive utility not only amplifies her team’s damage output but also makes it significantly easier to exploit enemy Weaknesses. Her Weakness Break Efficiency ensures quicker and more frequent breaks, keeping enemies in a weakened state for longer periods. Moreover, Ruan Mei can act as a secondary damage dealer, contributing consistent Ice Break DMG, even when she isn’t the one initiating the Weakness Break.

With her versatile kit and ability to continuously debilitate enemies, Ruan Mei is a game-changer in any team, making her one of the most impactful supports in Honkai: Star Rail.

#2: Bronya

• Rarity: Five-Star
• Type: Wind
• Path: The Harmony
• Best Synergy: Perfectly complements any character or team composition

Bronya is widely regarded as one of the most valuable five-star characters in Honkai: Star Rail, standing tall as a cornerstone support even as new units are introduced. Her exceptional utility stems not only from her potent buffs but also from her unique ability to manipulate the turn order, giving her team a significant tactical edge.

Her Skill is a game-changer, allowing her to:
• Advance a target ally’s action immediately, letting them take their turn regardless of their SPD.
• Apply a powerful DMG boost to the chosen ally.
• Cleanse any debuffs affecting them.

Her Ultimate takes her support capabilities even further by providing a team-wide ATK boost and enhancing their CRIT DMG, which scales with Bronya’s own CRIT DMG. This combination ensures your damage dealers can deliver devastating blows while maintaining momentum in combat.

Bronya’s ability to optimize turn efficiency and amplify team damage makes her an irreplaceable asset in nearly any scenario. Her kit is not only versatile but also incredibly impactful, cementing her place as one of the best support characters in the game.

#1: Sparkle

• Rarity: Five-Star
• Type: Quantum
• Path: The Harmony
• Best Synergy: Ideal for any team, especially those with Skill Point-heavy characters like Dan Heng: Imbibitor Lunae, Qingque, and Seele

Topping the list is Sparkle, a truly game-changing support character from the Harmony Path, and for good reason. Sparkle not only provides exceptional buffs that significantly amplify your team’s DMG output, but her unparalleled Skill Point restoration mechanic makes her a standout among supports. With Sparkle on your team, you can forget about conserving Skill Points and freely unleash powerful abilities.

Here’s what makes Sparkle so impactful:
• Her Skill advances a target ally’s action by 50%, enabling them to act faster and keep up the pressure. It also boosts their CRIT DMG, scaling with Sparkle’s own CRIT DMG, ensuring devastating attacks.
• Her Ultimate takes utility to another level by instantly restoring four Skill Points and increasing your team’s damage output every time a Skill Point is used, turning resource management into a strength rather than a limitation.

Sparkle’s ability to synergize with any team composition, especially those reliant on frequent Skill usage, makes her the ultimate support in Honkai: Star Rail. Whether you’re dominating with heavy hitters or sustaining relentless offense, Sparkle ensures your team runs at full capacity with no downtime.

Conclusion

Support characters are the backbone of any strong team in Honkai: Star Rail, providing essential buffs, debuffs, healing, and utility that elevate your squad’s performance. From game-changing Skill Point management by Sparkle to the turn manipulation of Bronya and the damage mitigation of Fu Xuan, each support offers unique abilities that can adapt to various playstyles and team compositions.

Choosing the right support is key to maximizing your team’s potential, allowing you to tackle even the toughest challenges with confidence.
