Castorice is one of the most talked-about characters in Honkai Star Rail as of 2025, and for good reason. As a Quantum and Remembrance path DPS, she brings a unique playstyle that revolves around high HP scaling and party-wide HP consumption for massive AoE damage. If you've been searching for tips about honkai star rail castorice, castorice hsr, or building a strong castorice team, this guide covers everything you need to know.

Castorice Overview and Lore

Castorice hails from Aidonia, a land where snow falls endlessly and the cycle of life and death is deeply revered. She's introduced as the daughter of the River of Souls and the Chrysos Heir, searching for the Coreflame of Death. Her story is rich with mythic undertones, and her quest is a major arc in HSR's current storyline. If you follow bilibili castorice fan content, you'll see how much players appreciate her animations and lore.

Castorice Kit Breakdown

Castorice's kit is centered around draining HP from all team members to boost her own damage and build up charges for her Ultimate, "Doomshriek, Dawn's Chime." Instead of normal energy, she uses a unique 'Newbud' charge system: for each point of HP lost by allies, Castorice gains a point, and when full, she can summon her memosprite, Netherwing.

Key Highlights:

• Skill: Consumes 30% of allies' current HP for big Quantum damage (single-target and splash).

• Ultimate: Summons Netherwing, a powerful AoE dragon that advances its action and reduces enemy resistance.

• Talent: Gains stacks of damage boost whenever allies lose HP, stacking up to 3 times.

• Passive: Once per battle, allies who would die enter a stasis effect, gaining a chance for revival if healed.

Her kit is SP-neutral, so she doesn't consume Skill Points, leaving more resources for your supports and healers.

Best Castorice Builds (Relics & Light Cones)

To maximize castorice hsr potential, you'll want to stack HP, Critical Rate, and Critical Damage.

Recommended Relic Sets:

• Poet of Mourning Collapse: Maximizes CRIT Rate for Castorice and her summon, Netherwing.

• Bone Collection (Planar Ornament): Boosts CRIT DMG, especially since Castorice scales so well with HP.

Best Light Cone:

• "Make Farewells More Beautiful" (her signature) for optimal DPS.

• Alternatives: "The Flower Remembers" or "Sweat Now, Cry Less" (Battle Pass exclusives). If you can't get those, prioritize high-base HP Light Cones even if effects don't activate.

Stat Targets:

Stat	Recommended Value
HP%	7000+
CRIT Rate	~100% in combat
CRIT DMG	150%+

Castorice Team Compositions

Building the ideal castorice team is actually more flexible than you'd expect. Her synergy with Abundance healers is crucial, as she drains HP frequently:

• Best Free-to-Play Option: Remembrance Trailblazer (E1+) provides CRIT DMG buffs and True DMG, plus accelerates Castorice’s turns.

• Top Support: Tribbie, whose universal buffs and HP scaling mesh perfectly with Castorice’s kit.

• Healer Choices: Gallagher or Luocha are highly recommended, as their frequent healing accelerates Newbud charge and keeps your party alive under heavy HP drain.

• Alternative DPS: Mydei and Blade (both HP scalers) can create explosive double-DPS teams with Castorice, sharing HP drain and ultimate cycling.

Gameplay Tips & Strategy

Playing castorice hsr effectively means balancing her massive HP drains with constant healing. Shielders are not recommended, as her kit revolves around direct HP recovery. Instead, focus on:

• Using healers who can restore huge HP amounts each turn.

• Timing Netherwing’s breath attacks to maximize ramping damage and unleash powerful finisher bursts (Wings Sweep the Ruins).

• Managing Newbud charge by letting your supports and DPS take hits and heal up quickly.

• Take advantage of her once-per-battle revive passive as a safety net in tough content.

Strengths and Weaknesses

Strengths:

• Extremely high AoE damage output.

• Self-sufficient with SP-neutral playstyle.

• Global revive passive (unique in HSR).

• Flexible and accessible team building.

• Defensive utility through healing and damage redirection to Netherwing.

Weaknesses:

• Requires strong healers for sustainable play.

• Poor F2P Light Cone options.

• Does not work well with shield-based sustain characters.

Eidolons and Traces

Castorice’s Eidolons provide significant boosts:

• E1: Massive DMG bonuses against weakened enemies.

• E2: Enables more powerful breath attacks with Netherwing and better HP management.

• E4: Increased incoming healing for the team.

• E6: Quantum RES PEN and even more Bounce attacks for Netherwing.

Investing in Skill, Ultimate, and Talent traces is the top priority for maximizing her effectiveness.

Final Thoughts

Whether you caught her reveal on bilibili castorice trailers or just want to try the second anniversary star, Castorice stands out in honkai star rail for both gameplay and narrative. She’s a must-pull for players lacking a top-tier Quantum DPS or anyone who enjoys innovative team mechanics and flashy attacks.

If you’re planning to build hsr castorice, focus on high HP, critical stats, and healers like Gallagher or Luocha. With the right team and setup, Castorice will carry you through high-level content with style and power.
