I’ve put together the Light Cones, Relics, Trace priority, stat priority, teams, and Eidolon verdicts for the best Castorice build in this guide, along with a full rotation breakdown and my honest verdict below.
Castorice is a 5-star Quantum Remembrance damage dealer who drains her own HP and her allies’ HP to summon her memosprite, Netherwing, and unleash huge AoE damage. She’s one of the strongest units currently available in Honkai Star Rail, and her entire kit runs on a resource system unlike almost anything else in the game.

How to Play Castorice: Rotation and Tips
Castorice’s Skill, Silence, Wraithfly’s Caress, drains 30% of every ally’s current HP to deal Quantum damage, and that lost HP is what fills her unique “Newbud” gauge instead of normal Energy. Once Newbud caps out, her Ultimate, Doomshriek, Dawn’s Chime, summons Netherwing and deploys a Territory that cuts every enemy’s All-Type RES.
With Netherwing out, her Skill upgrades into the Enhanced Skill, Boneclaw, Doomdrake’s Embrace, a full AoE joint attack that drains even more HP. From there you spam Netherwing’s own Memosprite Skill, Breath Scorches the Shadow, which ramps its damage multiplier with each repeated cast.
When Netherwing’s HP drops low enough, it auto-triggers Wings Sweep the Ruins, a finisher that hits six times and heals your whole party on the way out. Play around your sustain’s healing rhythm as much as your own turn order, since Castorice needs consistent healing to keep generating Newbud.
