Castorice Best Build

An HP-scaling Quantum carry who drains the entire team's health to summon Netherwing and unleash repeated AoE breath attacks.

Castorice build overview

Castorice is a Quantum Remembrance character commonly used for main dps, memosprite, hp drain. The recommended build focuses on the part of the kit used most often while keeping the team rotation reliable.

Use Poet of Mourning Collapse as the primary Relic set and Bone Collection's Serene Demesne as the Planar Ornament. Recommended main stats are CRIT Rate / CRIT DMG, HP%, Quantum DMG / HP%, HP%. Secure important Speed, Effect Hit Rate or Break Effect requirements first when the kit needs them, then improve the character's main scaling and offensive or defensive substats.

Light Cones and alternatives

Make Farewells More Beautiful is the premium Light Cone because its passive is designed around Castorice's core mechanics. The build remains functional without it. provide practical alternatives when their passives stay active in the selected team. Strong Relic stats can be more valuable than forcing a theoretical equipment upgrade with poor synergy.

Recommended teams

  • Premium team: Castorice, Cyrene, Evernight, Hyacine. This formation keeps Castorice in the core role while covering damage amplification, turn economy and sustain.
  • Alternative team: Castorice, Tribbie, Trailblazer, Hyacine. This formation keeps Castorice in the core role while covering damage amplification, turn economy and sustain.
  • Accessible team: Castorice, Trailblazer, Tribbie, Gallagher. This formation keeps Castorice in the core role while covering damage amplification, turn economy and sustain.

When replacing a teammate, preserve the same job rather than copying rarity alone: keep the required buffer or debuffer, maintain Skill Point economy and add a sustain suited to the encounter.

Trace priority

  • Lower priority: Lament, Nethersea's Ripple
  • High priority: Silence, Wraithfly's Caress
  • Highest priority: Boneclaw, Doomdrake's Embrace
  • High priority: Doomshriek, Dawn's Chime
  • Lower priority: Desolation Across Palms

Raise the ability that defines Castorice's main role first. Lower-impact abilities can remain below maximum until the character, Light Cone and important teammates have received their guaranteed upgrades.

Investment advice

Start with character and Light Cone levels, major Traces and correct main stats before extended Relic farming. An E0 build with a suitable alternative Light Cone is intended to be complete. Signature equipment and Eidolons are premium upgrades and should be compared with improvements to the rest of the account.
