Honkai: Star Rail Castorice Guide: Best Team Compositions Ranked

Castorice isn’t built for the ordinary. In Honkai: Star Rail, she stands apart as a DPS who rejects shields, ignores brute force, and thrives on the delicate balance of HP loss and recovery. Her Ultimate doesn’t charge through turns or hits, it feeds off the chaos of shifting health bars, rewarding smart synergy and perfect timing. To make her shine, users need more than just strong stats that move with her rhythm, enabling her charge loop without tripping over her mechanics. 

Top Meta Comp: Peak Synergy

 

 

Team: Castorice + Remembrance MC + Tribbie + Luocha

This composition is the current gold standard. Tribbie’s HP-scaling abilities naturally feed into Castorice’s ult charge requirements, while Remembrance Trailblazer (MC) brings True Damage, freeze utility, and RES PEN, keeping enemies controlled and vulnerable. Luocha provides healing without needing active turns, sustaining the team without negating Castorice’s HP-drain synergy. Altogether, it’s a smooth loop of survivability, utility, and offensive scaling.

Budget & Flexible Alternatives

For those without premium characters, there are solid replacements that still let Castorice shine:

• Ruan Mei: Adds RES PEN and DMG buffs while helping the team meet SPD requirements for Castorice’s Poet of Mourning Collapse relic set.
• Bronya: Her Action Advance helps Castorice rotate faster, and her CRIT DMG buff increases team output.
• Pela: A reliable DEF shredder, perfect for F2P or early players.
• Lingsha: Offers AoE healing and breaks DMG debuffs, supporting both survivability and offense.
• Gallagher: A budget healer who pairs well if his Ultimate is used with precision.

Aggro Double DPS: Speed Over Control
 

 

Team: Castorice + Mydei + Remembrance MC + Luocha

If players want to try full offense, swap in Mydei, who thrives on HP loss directly syncing with Castorice’s playstyle. This double-DPS setup turns the HP drain into an advantage, fueling both units’ Ultimates faster. MC keeps control and buffs flowing, while Luocha anchors the team with timely healing. The result is a faster-paced, high-risk-high-reward comp for players confident in their timing.

Castorice is no plug-and-play character, but with the right allies and strategic planning, she delivers exceptional performance. Whether you aim for meta dominance or a resource-conscious build, these compositions unlock her true potential in Honkai: Star Rail’s toughest fights.
