| HSR Castorice Character Overview
Castorice is a 5★ Quantum Remembrance character in Honkai: Star Rail. She generates Newbuds through ally HP loss and healing to summon a Memosprite. The Memosprite scales with her Max HP and detonates after acting, delivering AoE damage, making Castorice a core DPS for Remembrance teams.

| HSR Castorice Pulling Advice
· E0+0: Neither Eidolons nor signature Light Cone — just skip or try her kit without heavy investment.
· E0+1: Base Castorice only, no signature LC. Even at E0, she works well as the core of a Remembrance team.
· E1+1: E1 Castorice plus her signature LC. Offers smoother gameplay and higher output — a strong value pick.
· E2+1: E2 Castorice plus her signature LC. Marks a major power spike for the Memosprite’s damage; ideal for dedicated players.
Summary: For most players, 0+1 is sufficient. For moderate spenders, 1+1 is optimal. For hardcore Remembrance enthusiasts, 2+1 is worth considering.
| Conclusion
Castorice remains a core Remembrance DPS in 3.7 with her Newbud and Memosprite mechanics. With Cyrene’s arrival, her team value grows even stronger. 0+1 is enough for most players, 1+1 suits moderate spenders, and 2+1 is for dedicated fans. Overall, she is a solid pick to pull and build in Version 3.7.
