Note: The information in this article is based on leaks and is subject to change before official release.

Castorice is one of the two upcoming 5-star characters for Honkai: Star Rail Version 3.2. She is a Quantum Remembrance unit that relies on her powerful Memosprite, the Dead Dragon: Pollux, to deal tremendous damage with her ultimate. Castorice is a unique unit that doesn’t have a standard ultimate that requires energy. Instead, her ultimate is charged through various means, and once unleashed, she can summon Pollux. You can learn more information about Castorice’s skills and her constellations below.
