In Honkai Star Rail, players have several options when forming a team around Castorice, based on her potential for damage output. Although the purple-haired Chrysos Heir can function as a sub-DPS, she truly excels when supported by teammates who can enhance her damage. Both free-to-play and premium character choices are available to complement her abilities effectively.
This article presents various team compositions featuring Castorice in Honkai Star Rail, designed to assist players in overcoming challenging content such as the MoC gauntlets and Pure Fiction.
Optimal Castorice Team Compositions in Honkai Star Rail
1. Tribbie, Remembrance Trailblazer, Castorice, Gallagher/Luocha

Tribbie is one of the premier support characters for Castorice in Honkai Star Rail, providing significant buffs such as a 24% RES PEN and vulnerability enhancements that elevate her teammates’ damage potential. Additionally, Tribbie can unleash substantial damage on multiple foes, making her a vital asset to the team.
Teaming with Remembrance Trailblazer allows for the utilization of Tribbie’s buffs, further enhancing Castorice with a True Damage boost. For healing, Gallagher is an exceptional choice due to his area-of-effect (AoE) healing capabilities. Alternatively, Luocha can also fulfill the healer role effectively.
2. Sunday, Remembrance Trailblazer, Castorice, Gallagher/Luocha

This composition substitutes Sunday for Tribbie, offering unique benefits through buffs that enhance both Castorice and her memosprite. Sunday’s abilities also improve the team’s critical hit ratio and energy regeneration, allowing for more frequent use of Ultimates, which can be pivotal in tough battles.
Once again, Remembrance Trailblazer serves as a key support character, amplifying Castorice’s True Damage output. Gallagher or Luocha remains the go-to options for healing with their impressive AoE healing skills that don’t excessively drain skill points.
3. Ruan Mei, Remembrance Trailblazer, Castorice, Gallagher/Luocha

Ruan Mei, hailing from the Genius Society, is another excellent support unit for a Castorice team. She provides multiple buffs, enhancing overall damage, Break Efficiency, and RES PEN, while also offering a minor speed boost to the entire party. This makes Ruan Mei an invaluable ally.
As in the previous compositions, Remembrance Trailblazer adds a True Damage boost to Castorice, while Gallagher or Luocha ensures team longevity with their healing skills.
4. Pela, Remembrance Trailblazer, Castorice, Gallagher

This last team configuration is tailored for free-to-play players, incorporating Gallagher, Remembrance Trailblazer, and Pela with Castorice. Here, Remembrance Trailblazer enhances Castorice’s True Damage, while Pela specializes in defense reduction, enabling greater damage output from Castorice.
Gallagher stands out as one of the best free-to-play Abundance characters in Honkai Star Rail, due to his substantial healing capabilities that don’t require frequent field presence.
