Honkai Star Rail: Guide to Kafka's Best Build, Ascension Materials, and More

Kafka's Kit Overview

Kafka is a 5-Star Lightning character belonging to the Nihility path, introduced in Honkai: Star Rail during version 1.2. Her abilities focus on dealing Shock damage over time (DOT) and lowering the enemies' Lightning resistance, making her synergize particularly well with other DOT characters.

In her current form as a boosted 5-Star character on the Indelible Coterie Banner in version 3.5, she will eventually reappear as the Banner cycle continues.

Kafka Ascension Materials

  • x15 Thief's Instinct
  • x15 Usurper's Scheme
  • x15 Conqueror's Will
  • x65 Shape Shifter's Lightning Staff
  • 308,000 Credits

Kafka Eidolons

Obtaining duplicates of Kafka through Warping on Banners grants you Eidolons, which enhance her existing capabilities. Below are all of Kafka's Eidolons:

  • Da Capo (E1): Increases DOT received by the target by 30% for two turns after a follow-up attack by Kafka's Talent.
  • Fortississimo (E2): DOT dealt by all allies increases by 25% while Kafka is on the field.
  • Capriccio (E3): Upgrades Kafka’s Skill and Basic Attack, enhancing her damage output.
  • Recitativo (E4): Regenerates two Energy when an enemy takes damage from Shock inflicted by Kafka.
  • Doloroso (E5): Increases the level of Kafka's Ultimate and Talent by two.
  • Leggiero (E6): Enhances damage multiplier of Shock and extends its duration.

How to Play Kafka

Playing Kafka effectively requires manipulating DOT mechanics. Focus on applying as many DOT effects as you can, such as Shock, Wind Shear, Bleed, and Burn. Utilizing her Ultimate every two turns is crucial, as long as Shock remains active on enemies. Pairing Kafka with characters like Sampo or Serval can maximize her Damage Per Second (DPS).

Also, other team members should support Kafka by leveling her Speed and Energy regeneration. This way, she can unleash her Ultimate more frequently and sustain high damage rates.

Best Kafka Team Composition

To optimize Kafka's performance, forming a balanced team is vital. Recommended companions are:

  • Sampo or Serval: Excellent for providing extra DOT effects.
  • Tingyun: For buffs and energy regeneration.
  • Luocha: To enhance survivability.

Additionally, consider including characters who can exploit enemy weaknesses, like Silver Wolf, to make use of Lightning weaknesses effectively.

Best Kafka Relics

A recommended relic set for Kafka is the 4-piece Prisoner in Deep Confinement, which amplifies her damage output significantly against enemies suffering from multiple DOT effects.

Alternatively, a combination of the 2-piece Band of Sizzling Thunder or the 2-piece Musketeer of Wild Wheat sets can provide viable alternatives while you farm for better options.

Best Kafka Light Cone

Kafka's signature 5-Star Light Cone, Patience Is All You Need, is her optimal choice, enhancing her damage and simultaneously increasing her Speed upon attacking.

For a solid 4-Star alternative, consider Good Night and Sleep Well to further boost damage when attacking debuffed enemies.

Best Kafka Build Overview

For the ultimate Kafka experience:

  • Best Light Cone: 5-Star Patience Is All You Need.
  • Best Relics: 4-Piece Prisoner in Deep Confinement.
  • Best Planar Ornaments: Space Stealing Station.
  • Best Team Comp: Sampo, Tingyun, Luocha.

Feel free to adapt your build based on available characters and team synergy. Kafka is a potent asset for any team aiming for high DOT damage!
