Light Cone
Make Farewells More BeautifulMake Farewells More Beautiful raises Max HP, grants shared DEF ignore after own-turn HP loss and advances Castorice when Netherwing leaves.
When to use it : Trigger Death Flower through HP loss during Castorice's Skill turn or Netherwing's own Breath turn before the main damage sequence.
The Story's Next PageThe Story's Next Page raises Max HP by 16% and, after Netherwing attacks, raises Castorice and Netherwing's Outgoing Healing by 12% for one turn.
When to use it : This is a defensive healing option after Netherwing attacks, not a damage bonus.
The Flower RemembersThe Flower Remembers directly increases both Castorice's and Netherwing's CRIT DMG without requiring an ATK stat she cannot use.
As a four-star cone, it is a lower-rarity replacement that remains functional at S1 and avoids the limited five-star signature.
Relics
Poet grants Quantum DMG and 32% CRIT Rate to both slow wearer and memosprite, freeing HP and CRIT DMG substats.
When to use it : Keep final pre-combat SPD below 95 so both Castorice and Netherwing receive Poet's full 32% CRIT Rate.
Hero adds 12% ATK, then 6% wearer SPD while Netherwing is present and 30% CRIT DMG to both for 2 turns after Netherwing attacks.
World-Remaking Deliverer is a Remembrance fallback when its support condition is relevant.
Planar Ornaments
Bone Collection raises HP and shares its threshold CRIT DMG with the wearer's memosprite.
When to use it : Reach 5,000 sheet HP before combat so the full 28% CRIT DMG applies to Castorice and Netherwing.
Amphoreus provides CRIT Rate for Amphoreus-team compositions.
Duran is a follow-up team alternative; its conditional CRIT DMG is not a Netherwing stat.
Team lineup
Tribbie amplifies HP-based area damage, Remembrance Trailblazer supplies True DMG and a decisive advance, and Hyacine heals repeated drains while raising Max HP in combat.
When to use it : Sequence Hyacine's healing after party drains, and use Remembrance Trailblazer's advance on Castorice during Newbud building rather than interrupting Netherwing's own turns.

Castorice converts team HP loss and eligible healing into Newbud, summons Netherwing at full charge, then feeds the dragon HP for repeated Breath attacks.
How to play it
- 1Use Skill to drain the party and fill Newbud; let Hyacine restore HP so the next drain remains safe.
- 2At maximum Newbud, use the Ultimate to summon Netherwing, advance it by 100% and open the three-turn dragon window.
- 3During Netherwing's own turns, spend its HP on repeated Breath attacks; Castorice's enhanced joint Skill transfers further team HP into the dragon.
Sources and methodology
Editorial recommendations are written from released game data, then cross-checked against specialist calculations. They are not copied from a single tier list.
Review method
Prydwen and StarGuide were read independently and checked against the released local 4.4 kit; both qualify as primary Remembrance evidence because they analyze the memosprite rather than only Castorice. Statistics count Castorice's HP scaling and Netherwing's inherited combat state, with Hyacine's Max HP buff excluded from the sheet target. Rotation and team modeling count Newbud from allied HP loss and eligible post-heal conversion, Castorice's own turns and joint Skill, Netherwing's three own turns, each HP-consuming Breath action, and the dragon's disappearance; Netherwing is not treated as a passive summon.
