Kafka Gameplay

Kafka is a 5-star Lightning Nihility character who excels as a DoT-based DPS, dealing consistent damage through her abilities that trigger and amplify Damage over Time (DoT) effects. Her kit revolves around applying and detonating DoT, allowing her to significantly boost her damage output while maintaining constant pressure on enemies. This playstyle enables her to sustain high DPS throughout fights while remaining effective in prolonged battles.

Her combat performance heavily depends on properly managing and maximizing DoT effects on enemies. Once Kafka activates her Skill, she triggers all existing DoT, dealing immediate damage while keeping the effects active. Additionally, every instance of DoT application contributes to her overall damage, greatly increasing her DPS without relying on constant Skill Point consumption. Her Ultimate further amplifies her damage output by applying Shock to all enemies and triggering existing DoT, allowing her to unleash a powerful burst at the right moment. This makes her highly efficient in terms of team synergy while maintaining consistent pressure in battle.

Kafka’s kit encourages a playstyle centered around DoT synergy and proper timing of her Ultimate. Activating it when multiple DoT effects are active ensures maximum damage output. She synergizes best with teammates who can apply additional DoT or amplify damage, such as debuffers and supports, allowing Kafka to fully capitalize on her kit and deliver strong, consistent DPS throughout the fight.

Kafka Trace Priority

Trace	Priority
Talent	★★★★★ (Top)
Skill	★★★★ (High)
Ultimate	★★★★★ (Top)
Basic Attack	★ (Low)

Kafka’s Ultimate is her highest priority because it plays a major role in both applying and triggering DoT across all enemies. It applies Shock in AoE and immediately detonates existing DoT, making it one of her strongest sources of damage output. Leveling this trace significantly enhances her overall DPS and team-wide pressure, making it essential for maximizing her effectiveness.

Her Talent is the second priority. It allows Kafka to trigger additional DoT damage whenever allies attack, enabling consistent off-turn damage and greatly improving her overall DoT synergy. Upgrading this trace increases the frequency and impact of these detonations, making it a key part of her sustained DPS.

Kafka’s Skill should be leveled next, as it directly triggers all existing DoT on a single target. This makes it an important tool for amplifying damage output, especially against priority enemies. While it is used frequently, its impact is slightly lower compared to her Ultimate and Talent in full team compositions.

Her Basic Attack is the lowest priority. It contributes minimal damage compared to her other abilities and is rarely a focus in optimized rotations. Since Kafka’s kit revolves around DoT application and detonation, investing resources here provides the least benefit.

Kafka Best Light Cones

To select the ideal Light Cone for Kafka, evaluate your build against these three tactical needs rather than simply choosing by rarity:

Maximizing DoT-Based Damage: A large portion of Kafka’s damage comes from Damage over Time (DoT), including Shock and other DoT effects triggered by her abilities. Because of this, Light Cones that increase ATK, boost DoT damage, or enhance her overall scaling will significantly improve her performance and consistency in combat.
Improving Damage Consistency and Debuff Potential: Kafka’s kit revolves around triggering and amplifying DoT, making consistent application and debuff uptime essential. Light Cones that apply additional debuffs, increase enemy damage taken, or improve overall damage output help her maintain constant pressure throughout the fight.
Enhancing Overall Damage Consistency: As a Nihility character, Kafka excels at sustained damage rather than short bursts. Light Cones that offer stable stat boosts like ATK, increase DoT reliability, or improve her performance in extended fights will further strengthen her role as a consistent DoT DPS, maximizing her overall impact across all encounters.

Recommended Light Cone
Lies Dance on the Breeze (5★)	ATK: 582 \| DEF: 529 \| HP: 952 Skill: Increases the wearer's SPD by 18% / 21% / 24% / 27% / 30% . After the wearer uses an attack, there is a 120% base chance to inflict the "Bamboozle" state on every enemy target. While under the "Bamboozle" state, enemy targets have their DEF decreased by 16% / 18% / 20% / 22% / 24% for 2 turn(s). If the wearer's SPD is higher than or equal to 170, there is a 120% base chance to inflict the "Theft" state on every enemy target. While under the "Theft" state, enemy targets have their DEF decreased by 8% / 9% / 10% / 11% / 12% for 2 turn(s). When "Bamboozle" or "Theft" is repeatedly inflicted, only the most recently inflicted instance takes effect.
Patience Is All You Need (5★)	ATK: 582 \| DEF: 463 \| HP: 1058 Skill: Increases DMG dealt by the wearer by 24% / 28% / 32% / 36% / 40% . After every attack launched by wearer, their SPD increases by 4.8% / 5.6% / 6.4% / 7.2% / 8% , stacking up to 3 times. If the wearer hits an enemy target that is not afflicted by Erode, there is a 100% base chance to inflict Erode to the target. Enemies afflicted with Erode are also considered to be Shocked and will receive Lightning DoT at the start of each turn equal to 60% / 70% / 80% / 90% / 100% of the wearer's ATK, lasting for 1 turn(s).
Good Night and Sleep Well (4★)	ATK: 476 \| DEF: 330 \| HP: 952 Skill: For every debuff the target enemy has, the DMG dealt by the wearer increases by 12% / 15% / 18% / 21% / 24% , stacking up to 3 time(s). This effect also applies to DoT.

Blade Relics, Ornaments & Stats Priority

1. Relics

The 4-piece Prisoner in Deep Confinement set is the best choice for Kafka, as it significantly increases her DoT damage and allows her to ignore a portion of enemy DEF when multiple DoT effects are applied. Since her entire kit revolves around Damage over Time (DoT) and consistently triggering these effects, this set perfectly enhances her overall damage output and consistency in combat. As an alternative option, the 4-piece Eagle of Twilight Line is also a viable choice, as it provides Lightning DMG Bonus and advances her action after using her Ultimate. This helps improve her turn cycling and allows her to trigger DoT more frequently, ensuring stable performance in different scenarios.

Best Choice

1st

Eagle of Twilight Line

2-Pc: Increases Wind DMG by 10%.
4-Pc: After the wearer uses their Ultimate, their action is Advanced Forward by 25%.

2nd

Prisoner in Deep Confinement

2-Pc: Increases ATK by 12%.
4-Pc: For every DoT the enemy target is afflicted with, the wearer will ignore 6% of its DEF when dealing DMG to it. This effect is valid for a max of 3 DoTs.

2. Planar Ornaments

Revelry by the Sea is the best Planar Ornament for Kafka, as it synergizes directly with her DoT-based playstyle and enhances her overall damage output. Since Kafka’s kit revolves around DoT and consistently triggering these effects, this set provides the most reliable and efficient performance in extended fights. However, depending on your build and stat needs, you may also choose between Firmament Frontline: Glamoth or Space Sealing Station. Firmament Frontline: Glamoth increases ATK and further boosts damage output based on Speed, making it a strong option for improving her overall DPS, while Space Sealing Station provides a solid ATK% increase, serving as a consistent alternative for stable performance across different scenarios.

Recommended Planar Ornaments
Revelry by the Sea	2-Pc: Increases the wearer's ATK by 12%. When the wearer's ATK is higher than or equal to 2400/3600, increases the DoT DMG dealt by 12%/24% respectively.
Firmament Frontline: Glamoth	2-Pc: Increases the wearer's ATK by 12%. When the wearer's SPD is equal to or higher than 135/160, the wearer deals 12%/18% more DMG.
Space Sealing Station	2-Pc: Increases the wearer's ATK by 12%. When the wearer's SPD reaches 120 or higher, the wearer's ATK increases by an extra 12%.
