Honkai: Star Rail has revealed the rerun banner for the second phase of version 1.6, confirming that the five-star Nihility unit Kafka will be available until the next update. The current banner in Honkai: Star Rail simultaneously promotes both new characters and reruns, offering players as many options as possible to set up their party. It's accompanied by a free five-star unit, Dr. Ratio, who would be a useful addition to DPS teams that have at least one great damage dealer.
