Introducing Castorice, an impressive new Quantum DPS character in Honkai: Star Rail. Her gameplay revolves around HP scaling, allowing her to enhance her damage output while strategically reducing her team’s HP for the benefit of her and her summon. Moreover, she possesses a distinctive passive ability that enables her to resurrect a fallen ally once per battle, which can significantly influence the evolving meta of Honkai: Star Rail as passive abilities gain greater prominence among new character releases.
To harness the full potential of Castorice, prioritizing her level-up ascension and trace upgrades is essential. By enhancing her traces, players can maximize her damage potential, making her a formidable asset across various content tiers. Pre-farming her ascension materials can substantially streamline her progression, ultimately saving time for players who wish to optimize their gameplay. Given her unique specialization and versatility, early upgrades to Castorice are crucial to ensure competitive performance.

Castorice shares her trace materials with Aglaea as a Remembrance character and uses the same boss materials as Tribbie due to her affiliation with the Quantum type. Notably, her exclusive enemy drops are unique and have not been utilized by any other character thus far but can be farmed in advance.
