Castorice Overview

  • Rarity: 5-Star
  • Element: Quantum
  • Path: Remembrance
  • Role: Primary DPS with HP-scaling damage and a unique memosprite mechanic.

Castorice is a 5-star Quantum character on the Path of Remembrance, set to release in Phase 1 of Version 3.2 (April 8, 2025). Her kit revolves around summoning a memosprite (Netherwing) and managing a "Newbud" resource tied to HP loss, making her a sustained DPS who excels in prolonged fights. She’s Skill Point-efficient and thrives with HP-focused teams.

Castorice Kit Summary

Castorices Kit Leaks Make Her Op In Honkai Star Ra

  • Basic Attack: Deals Quantum DMG equal to 50% of Castorice’s Max HP to a single enemy.
  • Skill: Consumes 40% of all allies’ current HP (minimum 1 HP) to deal Quantum DMG equal to 50% of her Max HP to a target and 25% to adjacent enemies. Becomes "Boneclaw, Doomdrake’s Embrace" when Netherwing is active, enhancing damage.
  • Ultimate: Summons Netherwing, advances its action by 100%, and creates the "Lost Netherland" Territory, reducing enemies’ All-Type RES by 20%. Netherwing has 140 SPD and HP equal to 100% of max "Newbud." It acts 3 times or until its HP depletes, then disappears, dealing 6 instances of Quantum DMG (each 20% of Max HP) to random enemies and restoring HP to allies (20% of Max HP + 800).
  • Talent: Gains 1 "Newbud" per HP lost by allies. At max Newbud (based on team levels), her Ultimate unlocks. When allies lose HP, her and Netherwing’s DMG increases by 20% (stacks up to 3 times, lasts 3 turns). While Netherwing is active, Newbud gain stops, and allies’ HP loss converts to Netherwing’s HP.
  • Technique: Deals Quantum DMG to nearby enemies and starts battle with 25% of max Newbud.

Her playstyle focuses on HP manipulation and Netherwing uptime for maximum damage output.

Castorice Light Cones

Hq720 2

Currently there are only two Rememberance Light Cones that are usable on Castorice. If players do not have any of them, they should put on Castorice the cone with the highest base HP that they have.

Make Farewells More Beautiful (5-Star)

Increases Max HP by 30%. When the wearer or their memosprite loses HP during their turn, grants "Death Flower," ignoring 24% of enemy DEF for 2 turns. Advances action by 12% when the memosprite disappears.

Why It’s Best: Boosts HP for scaling, enhances damage via DEF ignore, and improves turn efficiency.

Sweat Now, Cry Less

Sweat Now, Cry Less is Castorice's best 4-star Light Cone since this provides a CRIT Rate boost and increased DMG for when her Memosprite deals DMG.

Castorice Relics

4-Piece Set: Poet of Mourning Collapse

  • 2-Piece: +10% Quantum DMG.
  • 4-Piece: +32% CRIT Rate if SPD is below 95.

Why It’s Best: Castorice’s base SPD (low) ensures the CRIT Rate bonus, and Quantum DMG boosts her output. Avoid SPD substats to maintain the effect.

Alternative 4-Piece: Genius of Brilliant Stars

  • 2-Piece: +10% Quantum DMG.
  • 4-Piece: Ignores 10% DEF (20% vs. Quantum-weak enemies).

Use Case: Strong against Quantum-weak foes, stacking with her Light Cone’s DEF ignore.

Planetary Set: Bone Collection’s Serene Demesne (2-Piece)

+12% Max HP; +28% CRIT DMG if HP is 5,000+ (applies to Castorice and Netherwing).

Why It’s Best: Enhances HP scaling and CRIT DMG, leveraging her high HP builds.

Main Stats

  • Body: CRIT DMG (since Poet provides CRIT Rate).
  • Feet: HP% (primary) or SPD (if tuning for breakpoints).
  • Planar Sphere: Quantum DMG%.
  • Link Rope: HP% (maximizes scaling).

Substats Priority

  • HP% (target 5,000-6,000).
  • CRIT DMG (150%+ with buffs).
  • CRIT Rate (stop at ~100% with Poet and buffs).
  • ATK% (minor boost).
