Kafka is a brand new 5-star Lightning unit in Honkai Star Rail hailing from the Path of Nihility. Here is a guide for Kafka in Honkai Star Rail.

Kafka was released alongside the second phase of version 1.2 within the game. She is exceptionally strong and brings a lot to the table. She is also the most free-to-play friendly unit up until this point.

She is a Nihility unit, but her damage scales off ATK stats and how much DoT (Damage over Time) she can stack on the enemy. The overall DoT stacking can lead to some really big numbers from her ultimate which in turn out-damages the likes of Jing Yuan by a mile.
