Top Light Cones for Castorice
Castorice can exclusively equip Remembrance Light Cones. Here are the recommended options:
- Make Farewells More Beautiful: Enhances her maximum HP and expedites turns when Netherwing vanishes, providing a substantial 30% DEF ignore.
- Sweat Now, Cry Less: Particularly potent at Superimposition 5, though the S1 variant is effective while collecting additional copies.
- Victory In a Blink: A viable free-to-play option, granting 12% CRIT DMG at Superimposition 1, and 24% at Superimposition 5.
Recommended Relics for Castorice
Best Relic Sets
As a Quantum-element DPS unit, Castorice excels with carefully selected Relic sets:
- 4-piece Poet of Mourning Collapse: Boosts outgoing Quantum damage and CRIT Rate, contingent on keeping her SPD below 110.

Best Planar Ornament Sets
For Planar Ornaments, consider these sets:
- Bone Collector’s Serene Demesne: This set significantly enhances maximum HP and CRIT DMG, especially when her HP exceeds 5000.
