Castorice is a 5-star Quantum Remembrance character in Honkai Star Rail who trades her team’s HP for some of the hardest-hitting AoE damage in the game. Her whole playstyle revolves around a single, high-risk resource: your party’s current HP. She spends it to summon a memosprite, Netherwing, and gets stronger the more that resource keeps flowing.

Story and Background: Who is Castorice in Honkai Star Rail?
Castorice is a Chrysos Heir from Aidonia, the land that reveres death, where snow falls without end. She’s the daughter of the River of Souls, and her personal journey revolves around searching for the “Death” Coreflame while carrying the duty implied by her own title, “Servant of Death.”
In her own introduction, she’s described as someone who must guard the lament of souls and carry the solitude that comes with her role, treating life and death as one continuous journey rather than two separate states. Her lore reflects quite nicely on her kit too, since Castorice’s entire design leans on the idea of HP or “life” itself as something constantly spent and renewed instead of being stagnant.
Her memosprite, Netherwing, is introduced alongside her as a dragon-like presence that changes how a fight looks the moment it’s summoned.
