Castorice

Remembrance
Builds Update3.3
Teams Update3.3
Castorice is a Quantum-element character who follows the Path of Remembrance. Her playstyle revolves around summoning her Memosprite, Netherwing, which requires charging her Newbud gauge. This gauge fills when the team’s HP is consumed or restored, or when enemies lose HP. Once fully charged, Castorice can unleash her Ultimate to summon Netherwing.

Best Cavern Relics

(2) Increases Quantum DMG by 10%.
(4) Decreases the wearer's SPD by 8%. Before entering battle, if the wearer's SPD is lower than 110/95, increases the wearer's CRIT Rate by 20%/32%. This effect applies to the wearer's memosprite at the same time.
This is currently the best 4-piece set for Castorice. Triggering the 32% Crit Rate bonus at the start of combat is easy thanks to her Bonus Ability, Inverted Torch, which instantly grants her 40% Speed afterward.
(2) Increases Quantum DMG by 10%.
(4) When the wearer deals DMG to the target enemy, ignores 10% DEF. If the target enemy has Quantum Weakness, the wearer additionally ignores 10% DEF.
This can be considered a good set option. It grants Castorice a 10% Quantum DMG boost, allows her to ignore 10% of the target’s DEF, and provides an additional 10% DEF ignore if the target has Quantum Weakness.
(2) Increases Max HP by 12%.
(4) When the wearer is hit or has their HP consumed by an ally or themselves, their CRIT Rate increases by 8% for 2 turn(s) and up to 2 stacks.
This set enhances Castorice’s HP and grants up to 16% Crit Rate for 2 turns. However, it offers lower overall damage output compared to other options.

Best Planar Ornaments

(2) Increases the wearer's Max HP by 12%. When the wearer's Max HP is 5000 or higher, increases the wearer's and their memosprite's CRIT DMG by 28%.
The Bone is currently her best Planar Ornament set, as it provides a decent amount of HP and increases her Crit DMG by 28%. Castorice only needs to reach 5000 HP to trigger the second buff, which is easily achievable for her.
(2) Increases the wearer's CRIT DMG by 16%. When a target summoned by the wearer is on the field, CRIT DMG additionally increases by 32%.
This set provides easy access to a Crit DMG buff of up to 48% for both Castorice and Netherwing.

HP / CRIT DMG / CRIT Rate / Effect RES
Castorice requires at least 7,000 HP for optimal damage and survivability, along with a minimum Crit Ratio of 60/170. If she is equipped with the Poet of Mourning Collapse set, her Speed must not exceed 103, as it will be reduced to 95—triggering the set’s highest Crit Rate bonus.

Best Light Cones

SourceLight Cone Event Warp
Engrave
Increases the wearer's Max HP by 30~60%. When the wearer or their memosprite loses HP during their own turn, the wearer gains "Death Flower." "Death Flower" allows the wearer and their memosprite to ignore 30~50% of the target's DEF when dealing DMG, lasting for 2 turn(s). When the wearer's memosprite disappears, advances the wearer's action by 12~24%. This effect can only trigger up to 1 time, and the trigger count resets every time the wearer uses Ultimate.
This is Castorice’s signature Light Cone. It significantly boosts her HP and grants the Death Flower buff, allowing both her and Nightwing to ignore 30% of the enemy’s DEF for 2 turns. Additionally, when Nightwing exits the battlefield, Castorice’s action advances by 12%.
SourceBattle Pass
Interdependence
Increases the wearer's CRIT DMG by 24~40%. The CRIT DMG dealt by the wearer's Memosprite increases by 24~40%.
This Light Cone is exclusively obtainable through the Nameless Honor Battle Pass and becomes redeemable at Level 30. It instantly boosts Castorice’s Crit DMG and further enhances the Crit DMG dealt by Nightwing.
SourceBattle Pass
Come Train!
Increases the wearer's CRIT Rate by 12~20%. When the wearer's memosprite is on the field, increases the DMG dealt by the wearer and their memosprite by 24~36%.
This Light Cone is exclusively obtainable through the Nameless Honor Battle Pass and becomes redeemable at Level 30. It initially boosts Castorice’s Crit Rate and significantly increases the damage dealt by both her and Nightwing after the summon is initiated.
