Kafka is excellent because she’s one of the best DoT (damage-over-time) enablers in the game. Her kit allows her to consistently trigger Shock and other DoTs, spreading them to all enemies with her Skill and Ultimate—making her ideal for multi-target encounters and sustained damage. Rather than relying on burst damage, Kafka steadily chips away at enemy HP every turn.
She also pairs exceptionally well with other DoT characters like Sampo and Luka, and her scaling with Effect Hit Rate and ATK gives her flexible build options that fit into many team compositions. Overall, Kafka is a unique DPS who thrives in longer battles where her debuffs can maximize their impact.
Best Cavern Relics
(2) ATK increases by 12%.
(4) For every DoT the target enemy 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.
This set boosts both Kafka’s raw attack power and the effectiveness of her damage-over-time effects, making it her best relic set for maximizing DoT output.
Best Planar Ornaments
(2) Increases the wearer's ATK by 12%. When the wearer's ATK is higher than or equal to 2,400/3,600, increases the DoT DMG dealt by 12%/24%.
This set is perfect for DoT characters like Kafka, as she can easily reach the high ATK threshold required to gain the maximum DoT bonus.

Prioritize ATK% to reach Revelry by the Sea’s high ATK bonus, then aim for around 67% Effect Hit Rate. After that, build Speed and Break Effect to further enhance DoT damage.
Best Light Cones
SourceLight Cone Event Warp
Spider Web
Increases DMG dealt by the wearer by 24~40%. After every attack launched by wearer, their SPD increases by 4.8~8.0%, 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 60~100% of the wearer's ATK, lasting for 1 turn(s).This is Kafka’s best Light Cone, as it boosts her overall damage and Speed, allowing her to take turns more frequently. It also automatically applies an additional Shock DoT when she attacks, making it easier and faster to spread DoTs across enemies. Finally, it increases her damage against already Shocked enemies—perfectly amplifying her role as a DoT enabler.
SourceLight Cone Event Warp
Crystallize
Increases the wearer's Effect Hit Rate by 40~60%. When the wearer deals DMG to an enemy inflicted with Wind Shear, Burn, Shock, or Bleed, each respectively grants 1 stack of Prophet, stacking up to 4 time(s). In a single battle, only 1 stack of Prophet can be granted for each type of DoT. Every stack of Prophet increases wearer's ATK by 5~9% and enables the DoT dealt to ignore 7.2~10.0% of the target's DEF.This is a strong alternative Light Cone for Kafka. It increases her Effect Hit Rate and DoT, making it easier for her to apply debuffs and deal more consistent damage over time. While it lacks the Shock-specific bonuses of her signature Light Cone, it remains a solid choice for enhancing Kafka’s overall debuff reliability and DoT performance.
SourceStellar Warp, Departure Warp, Character Event Warp, Light Cone Event Warp
Toiler
For every debuff the target enemy has, the DMG dealt by the wearer increases by 12~24%, stacking up to 3 time(s). This effect also applies to DoT.This Light Cone increases Kafka’s damage based on the number of debuffs on the enemy, stacking up to three times. Since her kit naturally applies multiple debuffs—such as Shock—and she often functions in DoT-focused teams, this Light Cone provides a reliable and consistent damage boost, especially in full debuff-oriented setups.
SourceStellar Warp, Light Cone Event Warp, Starlight Exchange, Stellar Convergence
Inheritor
Increases the wearer's DMG to debuffed enemies by 24~40%. When the wearer uses their Skill, the Effect Hit Rate for this attack increases by 18~30%, and ATK increases by 24~40%.This Light Cone boosts Kafka’s damage against debuffed enemies, increases her Effect Hit Rate, and enhances her Skill damage—making it easier for her to apply and amplify DoTs.
SourceUnderground Shop, Echo of War, Memo-Keeping Light Casket, Light Cone Manifest
Semibreve Rest
Increases the wearer's Break Effect by 16~32%, and increases their DMG to enemies afflicted with Shock or Wind Shear by 16~32%. This also applies to DoT.Fermata is a solid 4-star Light Cone for Kafka. It increases Break Effect and boosts damage against enemies afflicted with Shock or Wind Shear, which aligns well with her playstyle. Additionally, it enhances DoT damage against Shocked enemies, making it a reliable and accessible option for increasing her overall DoT output.
SourceLight Cone Event Warp
Mirage of Reality
Increases the wearer's Effect Hit Rate by 24~40%. When the wearer deals DMG to an enemy that currently has 3 or more debuffs, increases the wearer's CRIT Rate by 12~20%. After the wearer uses their Basic ATK, Skill, or Ultimate, there is a 100% base chance to implant Aether Code on a random hit target that does not yet have it. Targets with Aether Code receive 12~20% increased DMG for 1 turn.This Light Cone increases Kafka’s Effect Hit Rate and Crit Rate, and further boosts her damage when attacking debuffed enemies. It also applies Vulnerability, causing enemies to take more damage overall. These effects make it excellent for amplifying her DoTs and overall damage output, especially in teams that stack multiple debuffs.
