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 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.
Sweat Now, Cry LessSweat Now, Cry Less adds CRIT Rate and increases the damage of both wearer and memosprite while the memosprite is present.
When to use it : Use on a CRIT-scaling Remembrance damage dealer that keeps its memosprite on the field.
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.
Two-piece Longevous Disciple plus two-piece Scholar Lost in Erudition is a transition mix: Increases Max HP by 12%. Increases CRIT Rate by 8%.
It reuses strong pieces from two sets while a complete four-piece configuration with equivalent main stats and substats is still being farmed.
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.
Inert Salsotto is a ranked alternative with this two-piece effect: Increases the wearer's CRIT Rate by 8%. When the wearer's current CRIT Rate reaches 50% or higher, the DMG dealt by the wearer's Ultimate and Follow-Up ATK increases by 15%.
When to use it : Reach 50% CRIT Rate to activate the Ultimate and Follow-Up ATK bonus.
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.
