Element: Lightning.
Path: The Nihility (specializes in debuffs and DoT).
Strengths:
- Excels at applying and triggering the Shock DoT for consistent damage.
- Strong AoE (Area of Effect) damage, perfect for multi-target fights.

Why Kafka Matters?
Kafka’s value lies in her unparalleled synergy with DoT-applying teammates, enabling her to dominate battles by amplifying and triggering effects like Shock, Wind Shear, and Arcana. Whether you’re tackling Memory of Chaos or Simulated Universe, Kafka’s electrifying presence is undeniable.
How to Build Kafka in Honkai: Star Rail?
Building Kafka requires a focus on enhancing her DoT damage, effect hit rate, and attack stats. Below, we’ll cover her best relics, Light Cones, ornaments, and stat priorities to ensure she shocks the competition.
Kafka Best Relics and Sets
Relics are the backbone of Kafka’s build, boosting her Lightning damage and DoT output. Here’s the optimal setup:
- 4-Piece Band of Sizzling Thunder
2-Piece Bonus: Increases Lightning DMG by 10%.
4-Piece Bonus: When the wearer uses their Skill, ATK increases by 20% for 1 turn.
Why It Works: This set maximizes Kafka’s Lightning DoT damage and boosts her Skill, which is her primary DoT trigger. The ATK buff enhances her overall damage, especially in prolonged fights.
- Alternative: 2-Piece Band of Sizzling Thunder + 2-Piece Musketeer of Wild Wheat
Musketeer 2-Piece Bonus: Increases ATK by 12%.
Why It Works: If you’re struggling to farm a full Band set, this combination provides a solid ATK boost while maintaining some Lightning DMG. It’s a great early-game option for new players.
Where to Farm: Domain of Excelsior (Path of Destruction) for Band of Sizzling Thunder; Cavern of Corrosion for Musketeer of Wild Wheat.
Kafka Best Light Cones
Light Cones are Kafka’s weapons, and the right one can make or break her performance. Here are the top picks:
- Patience Is All You Need (5-Star, Signature)
Effect: Increases DMG dealt by the wearer by 24%. After every attack, SPD increases by 4.8% (up to 3 stacks). Inflicts Erode on hit enemies, dealing additional Lightning DoT.
Why It Works: This is Kafka’s best-in-slot Light Cone, tailored to her DoT playstyle. The DMG boost, SPD stacks, and extra DoT make her a nightmare for enemies.
- Good Night and Sleep Well (4-Star)
For free-to-play players, Good Night and Sleep Well is a fantastic four-star Light Cone alternative, increasing damage by 12% per debuff on the enemy (up to three stacks).
Effect: For each debuff on the enemy, DMG deals increases by 12% (up to 3 stacks). This also applies to DoT.
Why It Works: A fantastic free-to-play (F2P) option, this Light Cone shines in DoT-heavy teams where enemies are stacked with debuffs. It’s accessible via the Stellar Warp or Light Cone Manifest.
- Fermata (4-Star)
Effect: Increases Break Effect by 16% and DMG to enemies afflicted with Shock or Wind Shear by 16%.
Why It Works: Another F2P-friendly choice, Fermata boosts Kafka’s Shock DoT damage and is available through the Forgotten Hall shop.
Pro Tip: If you’re a new player, prioritize 4-star Light Cones like Good Night and Sleep Well, as they’re easier to obtain and Superimpose for extra power.
Kafka Best Ornaments
Planetary Ornaments enhance Kafka’s secondary stats. The best choice is:
- Firmament Frontline: Glamoth (2-Piece)
Effect: Increases ATK by 12%. When the wearer’s SPD is 135/160 or higher, DMG increases by 12%/18%.
Why It Works: Kafka benefits from the ATK boost, and the conditional DMG increase is easy to achieve with SPD substats or team buffs (e.g., Asta). This set pushes her DoT and direct damage to new heights.
Farm this set in the Simulated Universe and aim for an ATK% Link Rope and Lightning DMG Sphere to round out her build.
- Alternative: Space Sealing Station (2-Piece)
Effect: Increases ATK by 12%. If SPD is 120 or higher, ATK increases by an additional 12%.
Why It Works: A solid early-game option, this set is easier to farm and provides a reliable ATK boost for Kafka’s scaling.
Where to Farm: Simulated Universe (World 8) for Firmament Frontline; World 3 for Space Sealing Station.
Kafka Best Stats and Substats
To optimize Kafka’s performance, focus on the following stats:
- Body: ATK% or Effect Hit Rate. ATK% scales her DoT and direct damage, while Effect Hit Rate ensures her Shock sticks to enemies, making it essential for maximizing her output, especially in high-level content.
- Feet: SPD or ATK%. SPD is a key stat for Kafka, allowing her to act more frequently and trigger DoTs faster, which is crucial for her cycle-based damage. ATK% is a good alternative if SPD is already high (135+).
- Planar Sphere: Lightning DMG Bonus. Boosts her Shock DoT and overall Lightning damage.
- Link Rope: ATK% or Energy Regeneration Rate. ATK% maximizes damage, while Energy Regen ensures frequent Ultimates for AoE DoT detonation.
Substats Priority:
- Effect Hit Rate (aim for 80%+ with Light Cone bonuses)
- ATK%
- SPD
- Break Effect ( situational, for Weakness Break teams)
Example Build:
- Body: ATK% or Effect Hit Rate (aim for 80%+).
- Feet: SPD or ATK% (SPD priority if below 135).
- Sphere: Lightning DMG Bonus.
- Rope: ATK% or Energy Regeneration Rate.
- Substats: Effect Hit Rate (30%), ATK% (40%), SPD (10), Break Effect (10).
This setup ensures Kafka’s DoT lands consistently and deals maximum damage, making her a versatile DPS or sub-DPS.
How to Build Kafka’s Team Composition?
Kafka’s strength lies in her synergy with DoT-focused characters and supports who amplify her debuffs. Below, we’ll explore two team compositions: a free-to-play (F2P) team and a premium DoT team.
Kafka F2P Team
For new players or those on a budget, this F2P team leverages accessible characters to maximize Kafka’s potential:
- Kafka (Main DPS/Sub-DPS): Applies Shock DoT and triggers it with her Skill and Ultimate.
- Sampo (Sub-DPS): Inflicts Wind Shear DoT, synergizing with Kafka’s Skill to detonate multiple DoTs. His Ultimate also reduces enemy DEF.
- Asta (Support): Boosts team SPD and ATK with her Skill and Ultimate, allowing Kafka to act more frequently. Her Fire DMG adds minor DoT synergy.
- Natasha (Healer): Provides reliable healing and debuff cleansing, ensuring team sustainability.
Playstyle:
- Use Sampo’s Skill to apply Wind Shear DoT to enemies.
- Follow with Kafka’s Skill to trigger DoT and apply Shock.
- Use Asta’s Ultimate to buff SPD and ATK.
- Deploy Kafka’s Ultimate for AoE DoT detonation.
- Natasha heals as needed and cleanses debuffs.
This team is accessible early in the game, with Sampo and Asta amplifying Kafka’s DoT output and Natasha keeping everyone alive. It’s perfect for clearing story content and early Memory of Chaos stages.
Example Rotation:
Turn 1: Sampo Skill → Kafka Skill → Asta Ultimate → Natasha Skill (if needed)
Turn 2: Kafka Ultimate → Sampo Ultimate → Asta Skill → Natasha Basic
Kafka DoT Team (Premium)
For players with a deeper roster, this premium DoT team unleashes Kafka’s full potential:
- Kafka (Main DPS/Sub-DPS): Core DoT applicator and trigger.
- Black Swan (Sub-DPS): She is Kafka’s best teammate, as her Arcana stacks amplify DoT effects and trigger additional damage, boosting Kafka’s damage. Her Aether Code increases enemy DMG taken.
- Ruan Mei (Support): A top-tier support for Kafka, boosting team-wide damage, Speed, and Weakness Break efficiency, which enhances Kafka and Black Swan’s DoT output from Weakness Breaks.
- Huohuo (Healer): An ideal healer, providing Energy Regeneration, ATK% buffs, and cleansing to keep the team healthy and Kafka’s Ultimate uptime high.
Playstyle:
- Black Swan’s Skill applies Arcana DoT and stacks debuffs.
- Kafka’s Skill triggers DoT and applies Shock.
- Ruan Mei’s Skill buffs DMG and Weakness Break efficiency.
- Kafka’s Ultimate detonates all DoTs for massive AoE damage.
- Huohuo heals and buffs ATK with her Ultimate.
This team is a DoT powerhouse, with Black Swan and Kafka stacking multiple debuffs, Ruan Mei amplifying damage, and Huohuo providing sustain. It’s ideal for endgame content like Memory of Chaos and Apocalyptic Shadow.
Example Rotation:
Turn 1: Black Swan Skill → Kafka Skill → Ruan Mei Skill → Huohuo Skill
Turn 2: Kafka Ultimate → Black Swan Ultimate → Ruan Mei Ultimate → Huohuo Ultimate
Alternative Characters:
- Tingyun (Support): Replaces Ruan Mei for ATK buffs and energy regen.
- Luka (Sub-DPS): Changes Black Swan for Bleed DoT in F2P setups.
- Luocha (Healer): Replaces Huohuo for consistent healing.
Tips for Building Kafka
Here are some pro tips to elevate your Kafka gameplay, based on personal experience and community insights:
- Prioritize Effect Hit Rate: Her Shock DoT won’t apply if enemies resist it. Aim for 80%+ Effect Hit Rate (including Light Cone bonuses) to ensure reliability, especially in endgame content like Memory of Chaos.
- Master DoT Stacking: Kafka’s Skill triggers all DoTs on the target, not just her Shock. Pair her with characters like Sampo, Black Swan, or Luka to stack multiple DoTs (Wind Shear, Arcana, Bleed) for explosive damage.
- Time Her Ultimate Wisely: Her Ultimate deals AoE damage and detonates DoTs on all enemies. Use it when enemies have multiple DoTs stacked or during Weakness Break for maximum impact.
Invest in Traces: Kafka’s Traces (ability upgrades) are crucial for boosting her DoT damage and survivability. Prioritize her Skill and Talent, followed by her Ultimate. You’ll need materials like Obsidian of Dread, Thief’s Instinct, and Regret of Infinite Ochema. - Experiment with Playstyles: Kafka can function as a main DPS in hypercarry setups (with ATK buffers like Tingyun) or a sub-DPS in DoT teams. Test different team comps to find what suits your roster and playstyle.
- Farm Efficiently: Focus on farming Band of Sizzling Thunder and Firmament Frontline early, as they’re her best sets. Use Trailblaze Power wisely by targeting Caverns and Simulated Universe domains.
- Leverage Eidolons (If Available): Kafka’s Eidolons (similar to Genshin’s Constellations) enhance her DoT damage and debuff application. E1 (Da Capo) increases Shock duration, while E2 (Fortississimo) boosts DoT trigger damage. While not necessary for F2P players, they make her even deadlier.
When I first pulled Kafka, I underestimated her reliance on team synergy. Pairing her with Sampo and Asta significantly improved her from a decent sub-DPS to a DoT monster. Don’t sleep on her Skill’s ability to trigger ally DoTs—it’s a game-changer in multi-target fights like Simulated Universe!
Conclusion
Kafka is presented as a powerful and unique Lightning character in Honkai: Star Rail, excelling in DoT-focused team compositions. With the right build and strategy, Kafka will become a cornerstone of your roster, making even the toughest enemies tremble. With this build, we aim to help you unlock Kafka’s full DoT dominance, ensuring you can lead every battle with electrifying control and DoT.
