A pair of Honkai: Star Rail leaks have given players a glimpse into Dr. Ratio's combat animations and signature Light Cone. Honkai: Star Rail confirmed in a drip marketing campaign that new characters, such as Xueyi, Ruan Mei, and Dr. Ratio, will join the playable cast in version 1.6 later this year. The upcoming version will also add long-awaited Blade and Kafka reruns for a limited time. Players will have the opportunity to get their Eidolons if they previously pulled the two characters from the banner.
