With the arrival of Kafka, the face of Damage Over Time (DOT) mechanics in Honkai: Star Rail is set to undergo a transformative change.

Kafka, a stunning new addition, is all about DOTs, including high-scaling shock DOTs, which she can instantly trigger without waiting for the enemy's turn to naturally process the damage.

The more DOTs you apply to your enemy, the more damage Kafka can do.

Let's go deeper into her unique playstyle, skills, and her impact on the game.

Kafka: A Mesmerizing New Addition

Kafka brings a unique playstyle to Honkai: Star Rail.

She is the first character that the Trailblazer laid eyes on, marking a significant moment in the game's narrative.

Her skills provide an Area of Effect (AOE) lightning damage and have the potential to immediately produce DOTs.

Kafka's Abilities: A Comprehensive Look

Kafka's Abilities Honkai Star Rail

Skill: Blast Skill

Kafka's skill is where things begin to get interesting. It's designed to detonate DoT (Damage over Time) effects on the central target. This includes:

  • Ally DoTs: Any DoT effects applied by allies.
  • Break DoTs: Detonates break DoTs as well.
  • Exceptions: Certain statuses like Freeze, Entanglement, and Imprisonment are excluded as they are not classified as DoT effects.

AoE Damaging Ultimate

Her ultimate ability is a powerful area-of-effect attack with unique properties:

  • Detonation: It triggers all enemies' DoT effects, not just the central target's.
  • Shock Application: Applies a potent Shock effect, which, given her 5-star status, is expected to be highly damaging.

Talent: Shock Infliction

Kafka's Talent Details Honkai Star Rail

Kafka's talent serves as a follow-up action when an ally uses a basic attack, causing additional Shock.

Kafka's Shocks don't accumulate, meaning extra applications won't increase the Shock effect.

Technique: Attacking Move

Kafka's Technique Honkai Star Rail

An offensive technique that applies a Shock equal to the power of her ultimate.

It's a crucial part of her kit, allowing her to consistently apply the Shock status.

Traces and Ascension Passives

Kafka's traces and passives add more layers to her combat style:

  • Ultimate Enhancement: Enables her ultimate to detonate all DoTs.
  • Energy Gain: Provides energy regen when defeating enemies with Shock.
  • Shock Buffing: Enhances all of her Shock base chances.

Kafka's Ideal Build

Kafka’s build can be approached in different ways depending on your strategy. Here's a quick recommendation:

  1. Attack: Kafka's DOTs scale with her attack stat, so it's essential to boost this as much as possible. An ATK% body and an ATK% rope can contribute to this.
  2. Speed: Speed boots will allow Kafka to take turns more frequently, meaning she can apply and trigger DOTs more often. It's advised to ensure Kafka's DOT allies have slightly higher speed, so Kafka can trigger their DOT with her skill in her first turn.
  3. Energy Regen: Kafka's ultimate ability, which triggers immediate DOT damage, is a significant part of her kit. An Energy Regen rope can help her use her ultimate more frequently.
  4. Lightning DMG: Since Kafka's DOTs are of the lightning type, a Lightning DMG sphere can boost her damage output.
  5. Effect Hit Rate: How much Effect Hit Rate does Kafka need? If you want to increase Kafka's chance to apply shock with her ultimate to 100% (although she already has a 92% chance), you'll need around 28% effect hit rate from relic substats.

Understanding Kafka's Builds

The Importance of Speed and ATK%

Speed is vital for Kafka as it allows more instances of DoTs and detonations. Stacking ATK% and Speed is the foundation of her builds.

Kafka's Summary Honkai Star Rail

Kafka's ideal build could be an ATK% body, Speed boots, Lightning DMG sphere and ATK% rope.

As for the substats, you'll want to focus on ATK% and Speed for the best results, followed by Lightning DMG and Energy Regen.

Crit Kafka

  • While tempting, Crit Kafka may run into issues with limited substats.
  • Going for Crit may reduce Speed and ATK%, leading to fewer detonations and overall damage.
  • It's viable but may not be optimal as only a third of her damage scales on Crit.

Break Kafka

  • Focuses on Speed and Break Effect.
  • Requires breaking and/or bringing specific units like Serval.
  • Can work well, especially against Lightning Weak enemies.

Her reliance on ATK% and Speed offers a different approach to building her, and while Crit and Break Kafka might sound appealing, focusing on her core strengths may yield better results.

Best Relic Sets for Kafka

When it comes to relics, there are a couple of sets that stand out for Kafka:

Kafka's Best Set Band of Sizzling Thunder Honkai Star Rail
  1. Prisoner of Deep Confinement (4-piece set): Best set for Kafka as it synergizes extremely well with her DOT-focus damage. Boosts ATK% and ignores enemy DEF when the enemy is afflicted with 1/2/3 DOTs.
  2. Sizzling Thunder (4-piece set): This set is optimal for Kafka as it synergizes well with her lightning-based DOT damage. This set will increase her overall damage output significantly.
  3. Musketeer (4-piece set): If you don't have access to the Sizzling Thunder set, the Musketeer set is a good alternative. This set also provides damage boosts that Kafka can benefit from.
  4. Mix of Sizzling Thunder & Musketeer (2-piece each): A mix of these sets could be a good alternative too, heavily boosting Kafka's ATK and overall damage output.

Best Planetary Sets for Kafka

When it comes to planetary sets, there's only one that stands out for Kafka:

Kafka's Best Planetary Set Space Sealing Station Honkai Star Rail

Firmament Frontline Glamoth: Best in slot for Kafka if she can reach 135-160 speed breakpoints, as it boosts ATK and damage dealt.

Space Sealing Station (for extra ATK%): This set is recommended because it provides a significant boost to Kafka's attack. If you're running Kafka outside of DOT teams, you could consider the Broken Keel set to give everyone some extra critical damage.

Optimal Late Game Stats for Kafka

ATK: 3,500+

Speed: 135+

Effect Hit Rate: 28%+

Kafka's Best Teammates and Team Compositions

Kafka's Example Team Composition Honkai Star Rail

Kafka works best in teams that can apply and benefit from DOTs. Here are some potential teammates:

  1. Luka & Sampo: Sharing a banner with Kafka, these two characters, along with a defensive support unit, can form a powerful DOT team. Sampo is particularly valuable as he applies a different element DOT and increases the target's DOT damage taken. Luka applies bleed, deals raw damage, and helps with skill point management. However, triple DoT might be risky due to lack of survivability.
  2. Serval: A good alternative for Luka, Serval has a chance to shock the enemy with her skill and can extend the duration with her burst.
  3. Silver Wolf & Pela: These characters can reduce the enemy's defense, which significantly impacts the DOT formula. They also implant a weakness to an element and reduce the opponent's elemental damage resistance to that element.
  4. Asta: She can increase the team's speed and attack, and thanks to her Ascension 2 passive, she can also inflict Burn DoT to enemies, becoming a valuable support for Kafka's playstyle.
  5. Guinaifen: The new DOT addition can inflict burn and debuff enemies with her Firekiss talent, making her a perfect match for Kafka.

The best teams for Kafka are those that can support and amplify her DOT mechanic.

By choosing teammates that can apply their own DOTs or increase the damage of Kafka's, you can get the most out of Kafka's abilities.

Best Light Cones for Kafka

Light cones provide substantial stat boosts and unique effects. For Kafka, these are particularly valuable:

Kafka's Signature Light Cone Patience Is All You Need

Kafka's Signature Light Cone Patience Is All You Need Honkai Star Rail

Her signature light cone synergizes extremely well with Kafka, adding an extra DoT called Erode that does Lightning damage to the enemy afflicted with it. After every attack, it also increases Kafka's speed, stacking up to 3 times.

Resolution Light Cone and Defense Shred

Kafka's Light Cone Resolution Shines As Pearls of Sweat Honkai Star Rail

Stacking with Pela's Ultimate: Kafka's Resolution light cone can stack with Pela's ultimate, leading to a combination of different sources or named debuffs.

Defense Shred: This effect reduces the enemy's defense, making them more susceptible to Kafka's damage, especially her DoT (Damage over Time) effects.

Welt's Light Cone

High Base Stats: Welt's light cone is valuable for Kafka due to its high base ATK%, DMG buff, and skill damage buff.

Boosting DoTs during Detonation: This cone specifically enhances Kafka's ability to deal damage with her DoTs during the detonation phase. It complements her offensive abilities and Shock effects.

Good Night Sleep Well Light Cone

Kafka's Light Cone Good Night and Sleep Well Honkai Star Rail

Permanent Damage Boost: This light cone can provide Kafka with a permanent 72% damage boost if three debuffs are applied to the enemy. It's a powerful enhancement that aligns well with her ability to inflict multiple debuffs, including Shock.

Strategic Considerations for Kafka's Light Cones

  • Build Flexibility: The use of light cones allows Kafka players to experiment with different builds, such as focusing on ATK%, Speed, Crit, or Break Effects.
  • Team Composition: Selecting the right light cones can also influence the choice of teammates and overall team synergy, especially with characters that can amplify Kafka's Shock and DoT abilities.

In conclusion, Kafka's arrival means a shift in the DOT mechanics in Honkai: Star Rail.
