Castorice has quickly become one of the most sought-after characters in Honkai Star Rail as of 2025, thanks to her unique kit and massive impact in both endgame and casual content. As a Quantum and Remembrance path character, Castorice stands out with her HP-scaling damage and her ability to summon the formidable Netherwing. Whether you're exploring her playstyle for the first time or looking to optimize your castorice team, this guide covers everything you need to know about honkai star rail castorice.

Castorice Overview

Castorice is the daughter of the River of Souls from Aidonia, known as the Chrysos Heir. Her story brings a captivating blend of solemnity and hope, reflecting her role as a guardian of souls. In gameplay, Castorice is an AoE DPS whose damage scales directly with her Max HP, making her build and relic choices critical. With a base HP that surpasses all current Honkai Star Rail characters (over 16,000 at level cap), she’s unmatched in survivability and burst potential.

Kit and Mechanics

Castorice’s kit revolves around HP consumption and efficient healing. Her Skill, 'Silence, Wraithfly's Caress,' drains 30% of all allies’ HP to deliver enormous Quantum damage. This mechanic charges her unique "Newbud" resource, allowing her to summon Netherwing with her Ultimate once fully charged. Netherwing not only provides powerful AoE attacks but also grants All-Type RES PEN to all enemies, further amplifying team damage.

Her Talent provides stacks of DMG boost whenever allies lose HP, and the synergy between her Skill, Ultimate, and team healing creates a rapid gameplay loop. Notably, Castorice’s kit is SP-neutral, meaning she doesn’t use Skill Points—allowing supports and healers to maximize their utility.

Building Castorice: Relics and Light Cones

When it comes to relics, the Poet of Mourning Collapse set is the top choice for castorice hsr. It dramatically boosts CRIT Rate for both Castorice and Netherwing, letting you focus on CRIT DMG as your main stat. High HP% is essential—aim for 7,000+ HP to maximize damage output.

• Recommended Stats:

• HP%: 7,000+

• CRIT Rate: Aim for 100% during combat

• CRIT DMG: 150%+

For Planar Ornaments, 'Bone Collection' is best-in-slot, increasing CRIT DMG even further.

Light Cone selection is straightforward: 'Make Farewells More Beautiful' is Castorice's signature and offers her the best performance. Alternatives like 'The Flower Remembers' or 'Sweat Now, Cry Less' (Battle Pass) are solid, but the signature cone is highly recommended if available.

Castorice Team Compositions

Castorice teams are surprisingly flexible and free-to-play friendly. The core of any castorice team is a strong Abundance healer, such as Gallagher or Luocha, who can rapidly restore HP lost from Castorice’s Skills. Shielders should be avoided, as her kit relies on direct healing to function optimally.

Best Partners for Castorice

• Remembrance Trailblazer: Provides CRIT DMG buffs, True DMG, and action advance to boost Castorice’s damage cycle.

• Tribbie: Offers universal buffs and HP scaling synergy, making her an excellent support for both Castorice and other HP-scaling DPS.

• Mydei or Blade: Can pair with Castorice for double DPS setups, especially when both consume HP for their own damage cycles.

• Hyacine: The top-tier healer, capable of both team healing and boosting Max HP.

Here's a simple table to visualize a recommended team setup:

Castorice	Trailblazer (Ice)	Tribbie	Gallagher

Advanced Tips: Eidolons and Traces

Castorice’s Eidolons offer significant boosts, particularly E2 (allowing more frequent and powerful Netherwing attacks) and E6 (Quantum RES PEN and Bounce count increases). While not required for her to shine, they are top picks for spenders seeking maximum performance.

Her Trace priorities are:

• Skill: Highest priority for maximum damage.

• Ultimate & Talent: Equally important to boost AoE and DMG scaling.
