Kafka follows the Nihility, as you’d expect from someone who relies so much on DoT, and she deals lightning damage.
Kafka’s skill is Caressing Moonlight, which deals lightning against a target based on her attack stat and a smaller amount of damage to adjacent enemies. If the target has an active DoT effect, such as Bleed or Wind Shear, Kafka’s skill triggers one instance of damage from each active effect.
Twilight Trill is her ultimate, and it works a bit differently than you might be used to. Kafka deals lightning damage to all enemies based on her attack, but the initial damage is a little underwhelming. However, the ability has a 100 percent chance to inflict Shocked on all enemies, and they instantly take damage from it. This shocked state lasts for two turns, and they take damage based on at least 110 percent of Kafka’s attack at the start of each turn.
Kafka’s talent is Gentle but Cruel. She can launch a follow-up attack once per turn when one of her allies uses a basic attack, and these attacks inflict shock. It’s a nice way to get some extra utility out of basic attacks without having to spend skill points.
Unlike a lot of 5-star Star Rail characters, Kafka’s Eidolons are actually pretty good all around. Eidolon 1 gives her Talent a 100 percent base chance to buff the DoT her talent deals by 30 percent. Eidolon 2 buffs DoT dealt by all allies by 25 percent, which is excellent if you have Sampo or Serval. Eidolon 4 lets Kafka regenerate additional Energy whenever her Shocked status damages an opponent, which is basically all the time, and, Eidolon 6 increases the amount of damage her shock deals and extends its duration to three turns.
