Castorice
Yes for Remembrance/HP-drain teams—Castorice is a top Quantum carry. Ultimate “Doomshriek, Dawn's Chime” hits every enemy on the field in one cast. Best with Hyacine / Tribbie / Sunday / Ruan Mei. Wants strong healing throughput for memosprite/HP play. Skip when you refuse Remembrance sustain partners.
Castorice is a 5★ Quantum Remembrance Main DPS. Skill “Silence, Wraithfly's Caress” is the primary in-combat spend. Ultimate “Doomshriek, Dawn's Chime” is the payoff window for damage or team utility. This Phase 1 page covers kit text, gear targets, and pull notes—team comps stay empty until Phase 2.

Strengths
- Ultimate “Doomshriek, Dawn's Chime” hits every enemy on the field in one cast—level this before polishing filler traces.
- “Silence, Wraithfly's Caress” spends HP as a deliberate self-damage cost, so adjacent elites still take meaningful chip without waiting for Ultimate.
- Talent “Desolation Across Palms” The maximum limit of "Newbud" is related to the levels of all characters on the battlefield—miss the stack conditions and the burst window feels empty.
- Castorice’s memosprite/summon adds a second actor that hits and breaks without always spending the team’s Skill Points.
Weaknesses
- E0 without “Make Farewells More Beautiful” is still clearable, but the gap versus a signature copy is larger than a single eidolon for most Remembrance carries—plan the cone before deep eidolon hunting.
- HP-spend skills mean Castorice can soft-lock if sustain is weak or if a healer tops them up at the wrong time and breaks a low-HP / Charge condition.
- Spamming “Silence, Wraithfly's Caress” every turn without watching Skill Points strands the rest of the team—Castorice is often the SP sink.
- If “Doomshriek, Dawn's Chime” is still offline at the end of a MoC cycle, the build is usually Energy/ERR or rotation order—not a missing CRIT roll.
Trace Priority
Doomshriek, Dawn's Chime carries most of the kit’s damage or utility—level this first.
Silence, Wraithfly's Caress supports the main rotation—raise after the top priority traces.
Desolation Across Palms supports the main rotation—raise after the top priority traces.
Lament, Nethersea's Ripple is last priority outside of filling trace materials.
Stat Priority
Open with Technique if it helps, spend Skill to advance the kit’s resource, and hold Ultimate for the damage or buff window. Exact teammate order lands in Phase 2.
Open supports first, then spend the carry’s Skill/Ult inside the buff window. Exact order varies by the team tab above.
Light Cones
5★ · Path cone
Increases the wearer's Max HP by 0.3%. 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 0.3% 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 0.12%. This effect can only trigger up to 1 time, and the trigger count resets every time the wearer uses Ultimate.
Why it works —Signature / best-in-slot when owned—passive lines up with Castorice’s kit triggers.
5★ · Path cone
Increases the wearer's SPD by #1[f1]%. After the wearer uses Skill, increases the DMG dealt by all allies by 0.08%, lasting for 3 turn(s).
Why it works —Best accessible option for most accounts—raise superimposition when copies drop.
4★ · Path cone
Increases the wearer's CRIT DMG by 0.12%. When the wearer's memosprite uses an ability on an ally target, increases the DMG dealt by all ally targets by 0.08%, lasting for 3 turn(s).
Why it works —Budget path cone—fine while building the account.
4★ · Path cone
Increases the wearer's ATK by 0.16%. After the wearer uses Ultimate, increases the Basic ATK DMG dealt by the wearer and their memosprite by 0.2%, lasting for 3 turn(s).
Why it works —Budget path cone—fine while building the account.
Relics
Team Compositions
Primary Remembrance / HP team for Castorice. Hyacine, Tribbie, Luocha are the partners the kit / endgame clears assume first.
Core carry for this shell — owns the damage plan and sets the rotation pace.
Hyacine is the damage seat in this shell — build the supports around their rotation, not the reverse.
Tribbie is the Advance / DMG amp — time their Skill/Ult for the carry’s damage window.
Luocha covers HP / memosprite upkeep so the Remembrance loop does not collapse mid-wave.
Traces & Eidolons
Traces
Deals Quantum DMG equal to 70% of Castorice's Max HP to one designated enemy.
Consumes 30% of all allies' current HP. Deals Quantum DMG equal to 63% of Castorice's Max HP to one designated enemy and Quantum DMG equal to 38% of Castorice's Max HP to adjacent targets. If the current HP is insufficient, reduces the current HP down to 1. If Netherwing is on the battlefield, the Skill becomes "Boneclaw, Doomdrake's Embrace" instead.
Summons the memosprite Netherwing and advances its action by 100%. At the same time, deploys the Territory "Lost Netherland," which decreases all enemies' All-Type RES by 25%. If Castorice has the DMG Boost effect from her Talent, then this effect spreads to Netherwing. Netherwing has an initial SPD of 165 and a set Max HP equal to 100% of max "Newbud." After Netherwing experiences 3 turns or when its HP is 0, it disappears and dispels the Territory "Lost Netherland."
The maximum limit of "Newbud" is related to the levels of all characters on the battlefield. For every 1 point of HP lost by all allies, Castorice gains 1 point of "Newbud." When "Newbud" reaches its maximum limit, can activate the Ultimate. When allies lose HP, Castorice's and Netherwing's DMG dealt increases by 25%. This effect can stack up to 3 time(s), lasting for 3 turn(s). When Netherwing is on the field, "Newbud" cannot be gained through Talent, and every 1 point of HP lost by all allies (except Netherwing) will be converted to an equal amount of HP for Netherwing.
After using Technique, enters the "Netherveil" state that lasts for 20 seconds. While "Netherveil" is active, enemies are unable to actively approach Castorice. During "Netherveil," active attacks will cause all enemies within range to enter combat. At the same time, summons the memosprite Netherwing, advances its action by 100%, and deploys the Territory "Lost Netherland." Netherwing has its current HP equal to 50% of max "Newbud." After entering battle, consumes 40% of the current HP of all allies (except Netherwing). If Netherwing is not summoned after entering battle, Castorice gains "Newbud" by an amount equal to 30% of max "Newbud."
Consumes 40% of the current HP of all allies (except Netherwing). Castorice and Netherwing launch Joint ATK on the targets, dealing Quantum DMG equal to 37.5% and 62.5% of Castorice's Max HP to all enemies. If the current HP is insufficient, reduces the current HP down to 1.
Eidolons
When the enemy target's current HP is 80%/50% of Max HP or lower, the DMG dealt to it by "Boneclaw, Doomdrake's Embrace," "Claw Splits the Veil," "Breath Scorches the Shadow," and "Wings Sweep the Ruins" is 120%/140% of the original DMG respectively.

Modest E1: When the enemy target's current HP is 80%/50% of Max HP or lower. Helpful padding, not a build-defining unlock.
After summoning the memosprite Netherwing, Castorice gains 2 stack(s) of "Ardent Will." "Ardent Will" can stack up to 2 time(s) and can be used to offset the HP cost of Netherwing's Memosprite Skill, "Breath Scorches the Shadow" and advance Castorice's action by 100%. When using the next Enhanced Skill, Castorice gains "Newbud" by an amount equal to 30% of max "Newbud."

When breaking Weaknesses, triggers the Quantum Weakness Break effect. And the number of Bounces for Netherwing's Talent "Wings Sweep the Ruins" additionally increases by 3.
