⚠️ Investment Warning

Castorice is a high-investment character. She requires:

Signature Light Cone for optimal performance
Hyacine (dedicated healer) releasing next patch
Heavy trace and relic investment

New players should carefully consider before pulling.

Overview

Castorice is a 5-star Quantum Remembrance character who commands the summoned creature "Netherwing." Her unique kit revolves around consuming allies' HP to deal massive Quantum damage scaled off her own Max HP.

Why Castorice is S+ Tier (When Invested)

Massive HP-scaling Quantum damage
Netherwing summon provides additional damage instances
Mooncocoon passive prevents team wipes
Scales infinitely with HP investment
Dominates when paired with Hyacine

Key Mechanics

Mooncocoon (Exclusive Passive)

When ally receives killing blow, they enter Mooncocoon state
Delays becoming downed, allows normal actions
If HP restored or Shield gained before next turn, character survives
Triggers once per battle - emergency safety net

Netherwing (Summon)

Castorice's signature summon creature
Skill transforms into "Boneclaw, Doomdrake's Embrace" when Netherwing is active
Additional damage source scaling with Castorice's stats

HP Consumption Mechanic

Skill consumes portion of ALL allies' current HP
Damage scales with Castorice's Max HP
If HP insufficient, reduces to 1 HP (won't kill allies)
Requires strong healing support

Team Compositions

Castorice + Hyacine + Tribbie + Cyrene

Cyrene: Additional Remembrance synergy

Current Best

Castorice + Remembrance MC + Gallagher + Flex
RMC: Only F2P Remembrance teammate
Gallagher: Best accessible healer for HP drain

Budget Team

Castorice + RMC + Luocha + Flex
Luocha for emergency heals
Will struggle in high-end content

Important: Healer Requirements

Healer	Viability	Notes
Hyacine	★★★★★	Made for Castorice. Pull when available.
Gallagher	★★★★	Best current option. E2+ recommended.
Luocha	★★★	Works but not optimal
Natasha/Lynx	★★	Not recommended. Healing insufficient.

Trace Priority

Priority	Trace	Reason
1	Skill	Main damage + Netherwing transformation
2	Ultimate	Burst damage
3	Talent	Netherwing scaling
4	Basic ATK	Low priority

Gameplay Tips

HP Management: Monitor team HP constantly
Healer Timing: Use heals after Castorice's turn
Mooncocoon: Don't rely on it - it's emergency only
Netherwing Uptime: Keep summon active for transformed Skill
Stack HP: More HP = more damage. Simple.
