Shock lasts for 2 turn(s). While Shocked, enemies receive Lightning DoT equal to 116% (290%) of Kafka's ATK at the beginning of each turn.

Mercy Is Not Forgiveness

Gentle but Cruel

• After an ally of Kafka's uses Basic ATK on an enemy target, Kafka immediately launches 1 follow-up attack and deals Lightning DMG equal to 42% (140%) of her ATK to that target, with a 100% base chance to inflict Shock equivalent to that applied by her Ultimate to the attacked enemy target for 2 turns. This effect can only be triggered 1 time per turn.

trace 1

Torture

• When the Ultimate is used, enemy targets will now receive DMG immediately from all currently applied DoT sources instead of just receiving DMG immediately from the currently applied Shock state.

Plunder

• If an enemy is defeated while Shocked, Kafka additionally regenerates 5 Energy.

trace 3

Thorns

• The base chance for Ultimate, Technique, or the follow-up attack triggered by the Talent to inflict Shock increases by 30%.

Patience is All You Need

• Increases DMG dealt by the wearer by 24%. After every attack launched by wearer, their SPD increases by 4.8%, 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% of the wearer's ATK, lasting for 1 turn(s).

Good Night and Sleep Well

• For every debuff the target enemy has, the DMG dealt by the wearer increases by 12%, stacking up to 3 time(s). This effect also applies to DoT.
  

  • Best option after Kafka's Signature. A solid boost in DMG given that she often applies DoTs. However, to get the most out of it you need to have more copies. This Light Cone shines if you have it at S5.

Fermata

• Increases the Break Effect dealt by the wearer by 16%, and increases their DMG to enemies afflicted with Shock or Wind Shear by 16%. This also applies to DoT.

Solitary Healing

• Increases the wearer's Break Effect by 20%. When the wearer unleashes their Ultimate, increases DoT dealt by the wearer by 24% for 2 turn(s). Defeating the target suffering from the wearer's DoT allows the wearer to regenerate 4 Energy.

Prisoner in Deep Confinement
