In the vast and intricate world of Honkai: Star Rail, each character is a puzzle waiting to be solved, and Castorice is no exception. As a versatile and powerful unit, Castorice can excel in various roles depending on how you build her. Whether you’re a seasoned player or just starting your journey through the galaxy, this guide will help you unlock Castorice’s full potential and make her a cornerstone of your team.
Understanding Castorice’s Role
Castorice is a Physical DPS character with a unique set of skills that make her both a formidable attacker and a valuable team supporter. Her abilities revolve around dealing consistent damage while providing utility through her Tactical Gear. To maximize her effectiveness, you need to focus on building her as a primary damage dealer while ensuring she has the right equipment and relics to support her playstyle.
Key Skills to Focus On

Basic Attack: Gear Grinder
Castorice’s basic attack is her bread and butter. It has a fast animation and deals consistent Physical damage. Prioritizing her basic attack is crucial as it synergizes well with her other skills.

Skill: Tactical Shift
This skill allows Castorice to switch between different gears, each providing unique effects. The Purple Gear is particularly useful as it increases her attack speed, making it a must-have for any DPS build.

Ultimate: Full-Speed Gear Rotation
Her ultimate ability is a game-changer in prolonged battles. It significantly boosts her damage output and attack speed, making it ideal for boss fights and high-difficulty stages.

Optimizing Castorice’s Build
Building Castorice requires a balance of attack power, speed, and crit rate. Here’s how you can optimize her build:

Weapons

5-Star Weapon: The Claymore of the Ecliptic is the best choice for Castorice. It provides a significant boost to her Physical damage and attack speed.
4-Star Alternative: The Graviton Backbone is a solid option if you don’t have access to 5-star weapons. It enhances her crit rate, which is essential for a DPS build.

Relics

2-Set: The Deafening Wallop set is ideal for Castorice. It increases her Physical damage by 15% and enhances her basic attack damage by 15%.
4-Set: If you can afford it, the 4-set Deafening Wallop further boosts her damage output by 25% when using her basic attack.

Substats

Prioritize: Attack Speed, Crit Rate, and Crit Damage.
Secondary: HP and Defense to ensure she can survive longer in battle.

Team Synergy and Combat Tips
Castorice shines when paired with characters who can provide crowd control and healing. Here are some tips to make the most out of her in combat:

Team Composition

Pair her with characters like March 7th or Serval for crowd control.
Include a healer like Dan Heng or Pelta to keep her alive during prolonged fights.

Combat Strategy

Always start with her Skill (Tactical Shift) to switch to Purple Gear for increased attack speed.
Use her Ultimate during the enemy’s weak point phase to maximize damage output.

Case Study: Castorice in Action
In a recent World 3-4 run, Castorice proved to be a game-changer. Equipped with the Claymore of the Ecliptic and a 2-set Deafening Wallop, she was able to take down the boss in under 30 seconds. Her Full-Speed Gear Rotation ultimate ability was used during the boss’s vulnerable phase, dealing over 10,000 damage in a single burst.
