Castorice Trace Priority
Focus on unlocking Castorice's Major Traces first, followed by ability upgrades:
- Major Trace 1 (Contained Dark Tide): Transforms healing received by allies (excluding Netherwing) into "Newbud," directly fueling her Ultimate ability. When Netherwing is active, this healing instead restores Netherwing’s HP. Each ally’s converted healing is capped at 12% of "Newbud"‘s maximum capacity, and the total accumulated conversion resets after any unit takes action. To optimize this mechanic, coordinate healing just before Castorice’s turn to maximize "Newbud" accumulation or sustain Netherwing’s presence, enhancing overall team performance.
- Major Trace 2 (Inverted Torch): Enhances her and her summon, by increasing their Speed (SPD) when their current HP is at or above 50% of their maximum HP. Specifically, if Castorice’s HP is 50% or higher, her SPD increases by 40%. Similarly, when Dead Dragon: Pollux uses its skill "Dimscorch Breath" and deals fatal damage to all enemies or reduces their HP to a point where they cannot lose more HP, its SPD increases by 100% for one turn. This mechanic emphasizes the importance of maintaining Castorice’s and her summon’s HP above the 50% threshold to capitalize on significant SPD boosts, thereby enhancing their combat effectiveness and allowing for more frequent actions during battles.
- Major Trace 3 (Where The West Wind Dwells): Enhances her summon, by amplifying the damage of its "Breath Scorches the Shadow" ability. Each time Netherwing uses this skill, its damage increases by 30%, stacking up to six times and lasting until the end of the turn. This mechanic encourages strategic use of "Breath Scorches the Shadow" within a single turn to maximize damage output.
Trace Priority: Memosprite’s Skill > Memosprite’s Talent > Ultimate > Skill > Talent > Basic ATK.

Castorice Recommended Teams
In a hypercarry team composition, Castorice significantly enhances the primary damage dealer’s effectiveness through strategic debuffs and support mechanics. Her Ultimate ability summonsPollux and establishes the Lost Netherland Territory, reducing all enemies’All-Type Resistance by 20%, thereby amplifying the hypercarry’s damage output. Additionally, Castorice’s Talent, Stamen Nova, accumulates based on allies’HP loss, further boosting her and Pollux’s damage, which can synergize with the hypercarry’s attacks. Her ability to consume allies’ HP to fuel powerful skillsnecessitates pairing her with a strong healer to maintain team sustainability. This strategic interplay allows Castorice to significantly contribute to a hypercarry team’s overall effectiveness.
Furthermore, when paired with characters like Tribbie, who increases allies’All-Type RES PEN and increasing enemy’s damage taken, the combined debuffs substantially elevate the hypercarry’sdamage potential.

Additionally, partnering with Sunday, who offers CRIT DMGenhancements and Action Advances for both the memosprite and herself, further amplifies thehypercarry’s offensive capabilities. By incorporating Castorice alongside these synergistic allies, ahypercarry team can achieve unparalleled damage output and combat efficiency. While Pela reduces enemies’ DEF while also being SP positive.

Support 1 & 2: Tribbie / Remembrance MC / Sunday / Pela
