Castorice, a sought-after 5-star character from the Remembrance Path in Honkai Star Rail, is renowned for her ability to inflict substantial Quantum damage through her summons. However, her skill set primarily relies on HP scaling, presenting challenges in finding suitable team partners. Fortunately, players can utilize various neutral support characters and exceptional healers to enhance Castorice’s effectiveness in battle.
This article delves into some of the most effective teammates to pair with Castorice in Honkai Star Rail.
Top Teammates for Castorice in Honkai Star Rail
1. Tribbie

Tribbie stands out as an exceptional support character for teams incorporating Castorice, primarily due to her capability to provide significant resistance penetration (RES PEN). This ability directly boosts the damage output of both Castorice and her summons, making enemies more susceptible to her formidable attacks. Furthermore, Tribbie can unleash powerful area-of-effect (AoE) damage, trigger frequent follow-up attacks, and utilize various accessible Light Cones, solidifying her role as a valuable ally.
2. Ruan Mei

Ruan Mei is another excellent support choice for Castorice, particularly because of her HP-based kit. Similar to Tribbie, Ruan Mei offers substantial RES PEN to all allies, which allows their strikes to ignore enemy resistance. This advantage extends to Castorice’s summons that deal enormous Quantum damage. Additionally, Ruan Mei’s Netherwing can execute multiple attacks, effectively depleting enemy Toughness, especially when paired with her Weakness Break Efficiency buff to consistently create openings in enemy defenses.
3. Remembrance Trailblazer

The Remembrance Trailblazer has emerged as a vital teammate for characters from the same Path, including Castorice. With the ability to summon Mem, the Trailblazer can enhance the performance of other team members. Mem not only accelerates a teammate’s turn but also grants an instance of True damage with their attacks, significantly amplifying both Castorice’s and her summons’ damage output.
4. Gallagher

Gallagher is an essential healer for Castorice’s team, given that her abilities drain HP from allies to maximize Netherwing’s damage. He excels in replenishing teammates’ health and can deliver respectable damage output when necessary. As an easily obtainable 4-star character, his Eidolons can enhance his healing capabilities further and unlock supportive cleanses.
5. Luocha

Available for free during the Honkai Star Rail 3.2 anniversary, Luocha is an outstanding healer suited for Castorice’s team. His ability to cleanse allies and his auto-healing mechanics make him indispensable, especially when preventing fatal damage. Additionally, Luocha’s field can aid in HP restoration while Castorice deals damage. For optimal performance, focus on building him with high Energy Regen to maximize the use of his Ultimate, which is capable of removing enemy buffs.
