Should You Pull for Kafka?

Support DPS

Since Version 3.4, Kafka has moved fully into a support role for DoT teams. She keeps detonating the DoT effects already on enemies with her Skill, Ultimate and Follow-up ATK, and she gives a 100% ATK boost to allies with at least 75% Effect Hit Rate. Because she is a support rather than a pure damage dealer, she stays useful for a long time instead of ending up on the bench.

Worth pulling if you like the DoT playstyle and already have (or plan to pull) Black Swan or Hysilens. Hysilens in particular needs Kafka to reach her full strength, so if you are aiming for Hysilens, you should have Kafka.

Memory of Chaos Very strong She detonates DoT over and over, which pushes the burst damage of the whole DoT team very high.
Pure Fiction Very strong Her Ultimate hits every enemy, her Skill also detonates on adjacent targets, and Plunder restores Energy when a Shocked enemy is defeated.
Apocalyptic Shadow Outstanding The Follow-up ATK from her Talent keeps detonating on the main target, while her Ultimate detonates on every enemy.
Pros & Cons

Pros

  • An outstanding DoT support
  • Can detonate DoT effects on demand for enormous damage
  • Passively buffs the ATK of allies with at least 75% Effect Hit Rate
  • Does not need to care about CRIT at all
  • Her best Light Cone is a free one

Cons

  • Her own DoTs are fairly weak, since her main role is to be a launchpad for stronger DoT characters
  • Still needs an absurd amount of SPD
  • Fairly Skill Point hungry

Best Kafka Build Guide

DoT Support Build (Recommended)

This is how Kafka is played now: she runs with one or two other DoT characters and takes as many actions as possible to detonate their effects. She does not need CRIT at all. Just reach 75% Effect Hit Rate, then stack SPD.

Best Light Cones

  • 1 Before the Tutorial Mission Starts Before the Tutorial Mission Starts Best
    A 4-star that free-to-play players can get, and the top pick for support Kafka. It gives Effect Hit Rate, and with the right DoT teammates she can trigger its extra 8 Energy on almost every attack, Follow-up ATKs included. That lets her detonate far more often.
  • 2 Lies Dance on the Breeze Lies Dance on the Breeze Great
    A strong pick for both support Kafka and damage-focused Kafka. It raises her SPD and lowers the DEF of all enemies by 24%. She needs 170 SPD to get the full value out of it.
  • 3 Those Many Springs Those Many Springs Great
    Gives a lot of Effect Hit Rate and makes enemies take 24% more DMG. The catch is that you need 120% Effect Hit Rate or more to land that effect consistently. In return, since the Light Cone already has so much Effect Hit Rate, you can switch her Body to ATK%.
  • 4 Patience Is All You Need Patience Is All You Need Good
    Her signature Light Cone leans toward her own damage, but it still works for the support role thanks to its SPD boost. It also puts a separate Lightning DoT on enemies, giving her one more thing to detonate.
  • 5 Resolution Shines As Pearls of Sweat Resolution Shines As Pearls of Sweat Stopgap
    A support option that is easier to get than the 5-stars above, so aim for it at Superimposition 5. Use it if you don't have Before the Tutorial Mission Starts or don't want to put it on Kafka.

Best Relics

1
The best set for support Kafka. Every time she uses her Ultimate, her next turn comes sooner, so she acts more often and detonates DoT more often.
2
If you don't have 4 good Eagle pieces yet, use this 2 + 2 mix for Lightning DMG and SPD. Besides these two, you can also take 2 pieces from Sacerdos' Relived Ordeal, Warrior Goddess of Sun and Thunder or Pioneer Diver of Dead Waters, as long as the main stats and substats are good.

Best Planar Ornaments

1
The number one choice when Kafka plays support. It gives Energy Regeneration Rate so she can use her Ultimate more often, plus an ATK buff. Remember to put your other DoT character in the first slot of the team.
2
Use this if you are struggling to reach 75% Effect Hit Rate.

Main Stats

  • BodyEffect Hit Rate or ATK%
  • FeetSPD
  • Planar SphereLightning DMG Boost or ATK%
  • Link RopeEnergy Regeneration Rate or ATK%

Substats

  • 1Effect Hit Rate (until 75%)
  • 2SPD
  • 3ATK%

Effect Hit Rate and ATK% both work on Body. If your Light Cone already gives a lot of Effect Hit Rate, like Those Many Springs, take ATK%. Feet is always SPD. On the Planar Sphere, Lightning DMG Boost is equal to or a little better than ATK%. On the Link Rope, go for Energy Regeneration Rate so she gets her Ultimate often, with ATK% as the backup.

Once you have 75% Effect Hit Rate, SPD is the most important stat. The more turns Kafka takes, the more she detonates and the faster her Follow-up ATK uses come back.

Stat Targets

  • Effect Hit Rate75% (more is fine if your Light Cone needs it)
  • SPD160+ (156 at minimum), 170 with Lies Dance on the Breeze
  • ATK2500+
  • HP3000+
  • DEF900+

Skill Priority

Ultimate = Skill > Talent > Basic ATK

Her Ultimate and Skill are her two main sources of damage, so level them equally. Max both before moving on to her Talent. Kafka almost never uses her Basic ATK, so leave it for last.

Trace Priority

Torture > Thorns > Plunder

Torture raises the ATK of any ally with at least 75% Effect Hit Rate by 100%, Kafka included. Thorns lets her Follow-up ATK detonate DoT and gives back 1 Follow-up ATK use each time she uses her Ultimate. Plunder restores 5 Energy when a Shocked enemy is defeated. All three matter a lot, so unlock them early.

Eidolon Priority

E1 is the one most worth getting

E1 Da Capo makes targets Kafka attacks take 30% more DoT for 2 turns, so if you want an Eidolon, get this one first. E2 Fortississimo raises the DoT of the whole team by 33%. E4 Recitativo helps her regenerate Energy a little faster. E6 Leggiero greatly increases her own Shock DMG and makes Shock last 1 turn longer.

Main DPS Kafka Build

For players who want Kafka to deal the damage herself, or who don't plan to run her with another DoT character.

Best Light Cones

  • 1 Patience Is All You Need Patience Is All You Need Best
    Her signature and the best pick for damage-focused Kafka. It has high base stats, raises her damage, and gives a stacking SPD buff so she can use her Skill more often, plus a separate Lightning DoT on enemies.
  • 2 Reforged Remembrance Reforged Remembrance Great
    Gives Effect Hit Rate, raises her ATK and lets her DoT ignore part of the enemy's DEF.
  • 3 Good Night and Sleep Well Good Night and Sleep Well Great
    A pure damage 4-star that raises her DMG for every debuff on the enemy. It does little for her teammates, but it clearly lifts Kafka's own damage.
  • 4 In the Name of the World In the Name of the World Good
    Raises her DMG against debuffed enemies and raises her ATK when she uses her Skill.
  • 5 Eyes of the Prey Eyes of the Prey Stopgap
    A damage-focused 4-star that also gives Effect Hit Rate, which helps you reach the 75% needed for Torture.

Best Relics

1
The best set when Kafka is the main damage dealer. The more DoTs an enemy has on it, the more DEF she ignores. In DoT teams, though, this set raises Kafka's own damage but usually leaves the team's total damage lower.
2
The second choice, raising her Lightning DMG and ATK%.

Best Planar Ornaments

1
The best set for maximizing Kafka's own damage. It boosts her DoT once she reaches 2400 or 3600 ATK.
2
A weaker alternative to Revelry by the Sea, but it still adds solid damage even if you only reach the 135 SPD breakpoint.
3
A placeholder for the early game. Its ATK% boost makes her DoT stronger.

Main Stats

  • BodyATK%
  • FeetSPD
  • Planar SphereLightning DMG Boost
  • Link RopeATK%

Substats

  • 1SPD
  • 2ATK%
  • 3Effect Hit Rate

This build puts everything into ATK and SPD. Get your Effect Hit Rate from substats to reach the 75% needed for Torture.

Keep Kafka slower than the other DoT characters in the team, so she acts after them and detonates the effects they just applied.

Best Kafka Teams

Best DoT Team

Replace Dan Heng • Permansor Terrae with: Huohuo, Gallagher, Luocha

A team with three DoT characters, and it works especially well with Hysilens. Hysilens and Black Swan apply the effects, and Kafka detonates them with her Skill, Ultimate and Follow-up ATK, and every detonation also triggers the effect of Hysilens' Ultimate. Dan Heng • Permansor Terrae provides shields and an ATK buff for the main damage dealer, which stacks nicely with Kafka's Torture.

Team with Ruan Mei

Replace Hysilens with: Black Swan Replace Ruan Mei with: Robin, Jiaoqiu, Silver Wolf Replace Huohuo with: Dan Heng • Permansor Terrae, Gallagher, Luocha

Kafka's standard setup: one more DoT character, one support, and one healer or shielder. Ruan Mei raises DMG and gives RES PEN, and her Ultimate delays enemies' turns, so DoT gets triggered more often. If you don't have Ruan Mei, Silver Wolf is the replacement, especially when the team needs Weakness Break.

Budget Team (All 4-Stars)

Replace Guinaifen with: Sampo, Luka, Serval Replace Natasha with: Gallagher

This team focuses on applying DoT and raising Kafka's SPD. Asta gives ATK% and SPD and can also inflict Burn on enemies. Pick the DoT slot based on the enemies: Guinaifen against Fire-weak enemies, Sampo against Wind-weak enemies, and Luka against Elite enemies weak to Physical.

Best Teammates for Kafka

Hysilens
Hysilens

Kafka is Hysilens' best teammate, and playing Hysilens without her is hardly an option. Hysilens wants allies who attack often and trigger DoT, and Kafka does both, so Hysilens' Ultimate and Talent effects keep getting triggered.

Black Swan
Black Swan

The classic pairing. Black Swan's DoT is always on enemies and keeps stacking up, so every detonation from Kafka has something to hit. Her Ultimate also makes enemies take more DMG.

Ruan Mei
Ruan Mei

Raises DMG, gives RES PEN, and her Ultimate delays enemies' turns, so DoT gets triggered more often.

Jiaoqiu
Jiaoqiu

Makes enemies take more DMG and applies his own DoT, which gives Kafka more to detonate and helps the Prisoner in Deep Confinement set.

Robin
Robin

Raises the ATK and DMG of the whole team, and after her Ultimate she advances everyone's turn.

Cipher
Cipher

Strong damage amplification and very Skill Point friendly. A great fit for fights with few targets, where the extra amplification helps bring bosses down faster.

Tribbie
Tribbie

Excellent damage amplification and high AoE damage of her own, so she fits fights with lots of enemies.

Dan Heng • Permansor Terrae
Dan Heng • Permansor Terrae

Provides shields, an ATK buff and extra damage for the main DoT damage dealer, which stacks well with Kafka's Torture.

Guinaifen
Guinaifen

A 4-star DoT character who is strong against Fire-weak enemies and makes enemies take more DMG.

Asta
Asta

A 4-star support who gives ATK% and SPD and also inflicts Burn for Kafka to detonate.

How to Play Kafka

Kafka Detonates DoT

Kafka has 3 ways to make the DoT effects on enemies deal damage right away. Her Skill Caressing Moonlight detonates them on the main target (75% of the original DMG) and on adjacent targets (50%). Her Ultimate Twilight Trill hits all enemies, inflicts Shock and detonates every DoT on them. The Follow-up ATK from her Talent (thanks to the Thorns Trace) detonates them on the target it hits. Shock lasts 2 turns, and at the start of each of their turns, enemies take Lightning DoT equal to up to 290% of Kafka's ATK.

When Allies Attack, Kafka Follows Up

Her Talent Gentle but Cruel now triggers after any attack from a teammate, not only Basic ATK. Kafka launches a Follow-up ATK that deals 140% of her ATK and has a 100% base chance to inflict Shock. It can trigger up to 2 times, with 1 use recovered at the end of Kafka's turn. With the Thorns Trace, each Ultimate gives back 1 more use, and the Follow-up ATK also detonates every DoT on the target for 80% of the original DMG.

The 75% Effect Hit Rate Mark

The Torture Trace raises the ATK of any ally with 75% Effect Hit Rate or more by 100%, and Kafka benefits too. To land Shock reliably she only needs about 67%, but the ATK boost is so big that you should just go to 75%. Nihility teammates usually build Effect Hit Rate anyway, so they can easily get this buff as well.

SPD Is Her Most Important Stat

Her Follow-up ATK uses come back mainly on Kafka's own turns, and her Ultimate gives back 1 more. So the more turns she takes and the sooner she gets her Ultimate, the more times she can detonate. Once you have 75% Effect Hit Rate, SPD is the stat to chase.

Quick Tips

  • Use her Technique before fights: Kafka deals Lightning DMG to all enemies with a 100% base chance to inflict Shock for 2 turns right at the start.
  • If she uses Lushaka, the Sunken Seas, put your other DoT character in the first slot of the team.
  • If she uses Lies Dance on the Breeze, aim for 170 SPD to get the most out of it.
  • Kafka almost never needs her Basic ATK, so save your materials for her Skill and Ultimate.
  • Plunder shines against lots of small enemies: every Shocked enemy defeated gives Kafka 5 extra Energy.

Kafka FAQ

Is Kafka worth pulling?
Yes, if you like the DoT playstyle and already have characters like Black Swan or Hysilens. Since Version 3.4 she is a support for DoT teams, so she stays useful for a long time.
Is Kafka a DPS or a support?
These days Kafka is mainly a support who detonates DoT for her teammates. You can still build her as the main damage dealer with Prisoner in Deep Confinement and Revelry by the Sea, but she is at her strongest as a support in DoT teams.
What Light Cone should Kafka use without her signature?
She doesn't need her signature, especially in the support build. Before the Tutorial Mission Starts is the top pick, and Lies Dance on the Breeze is also very strong if you reach 170 SPD.
Does Kafka need CRIT?
No. Most of her damage comes from DoT, and DoT can't CRIT. Focus on Effect Hit Rate, SPD and ATK instead.
Which Eidolon should you aim for?
E1 is the one most worth getting: targets Kafka attacks take 30% more DoT for 2 turns, and the whole team benefits.
