Castorice Premium (Cyrene Evernight) — Build Order for Honkai Star Rail
Quantum Remembrance dual-DPS path built around Castorice and March 7th • Evernight, with Cyrene as the Chrysos amplifier and Hyacine as sustain. Phase 1 assembles the four-Chrysos-Heir core; Phase 2 adds signature light cones for Hyacine and Castorice; Phase 3 covers eidolons and deep investment for endgame ceilings.
Team composition
Characters: Castorice, Cyrene, Hyacine, March 7th • Evernight.
How does the build order work?
Each path is split into phases — Team Assembly, then Core/First Upgrades, then Deep/Premium Investment. Phase 1 marks the point where the team is fully functional at E0 with free or low-cost light cones. Phase 2 covers the upgrades most players will want. Phase 3 is for dedicated spenders pushing endgame ceilings.
Each step is annotated with a one-paragraph reason explaining mechanically why that pull or eidolon comes when it does, so the order is auditable rather than prescriptive.
What if I'm missing a character?
Investment paths assume you're building toward this exact composition. If you're missing a core character, check the Pull Advisor to see how each character would change your account before committing pulls, or open the Best Teams generator to see what alternative compositions your current roster supports.
