Honkai: Star Rail character guide
Castorice Best Build
An HP-scaling Quantum carry who drains the entire team's health to summon Netherwing and unleash repeated AoE breath attacks.
Castorice build overview
Castorice is a Quantum Remembrance character commonly used for main dps, memosprite, hp drain. Castorice's build supports main dps, memosprite, hp drain while keeping the team rotation reliable.
Use Poet of Mourning Collapse as the primary Relic set and Bone Collection's Serene Demesne as the Planar Ornament. Recommended main stats are CRIT Rate / CRIT DMG, HP%, Quantum DMG / HP%, HP%. Castorice should meet the listed Speed, Effect Hit Rate or Break Effect target first. Then improve the main scaling stats.
Light Cones and alternatives
Make Farewells More Beautiful is the premium Light Cone because its passive is designed around Castorice's core mechanics. Castorice can use the listed Light Cones when their passives match the team rotation. For Castorice, keep the Relic setup with stronger main stats and useful substats.
