Dr. Ratio Release Date
Dr. Ratio will debut alongside Honkai Star Rail Version 1.6, which is currently slated to release in early 2024. Before then, the Version 1.5 update will introduce new characters like Huohuo and Argenti.
It’s still unknown whether Dr. Ratio will be featured on the first or second limited banner of Version 1.6, however. Ruan Mei is the other new 5-Star character debuting in Version 1.6 alongside Dr. Ratio, so she may be the better choice for your Stellar Jades if you need an Ice Harmony character instead of an Imaginary character on the Hunt Path.
