Is Castorice Worth Pulling?
Castorice is a powerful Remembrance DPS that can summon Netherwing and consume the party's HP to deal high AoE DMG. Castorice is also very free-to-play friendly in terms of team-building since characters such as the Remembrance Trailblazer and Gallagher should be enough for her.
If you don't have a Quantum DPS or a DPS coming from Version 3.0 onwards, Castorice is worth pulling for. Her unique Global Passive is a great bonus to have in your account since it helps you keep your party alive for much longer.
Should I Get Castorice's Light Cone?
While Castorice's teams can be free-to-play friendly, her Light Cone options on the other hand are limited. Make Farewells More Beautiful, Castorice's signature Light Cone, will help her a lot in terms of DPS.
Other viable options include The Flower Remembers or Sweat Now, Cry Less, both Battle Pass-exclusive Light Cones, or high Base HP Light Cones. Unless you have either Battle Pass Light Cone, getting Castorice's Light Cone is a must!

The Poet set is the best relic for Castorice since it increases the CRIT Rate of both her and her Memosprite. Since the Poet set provides a lot of CRIT Rate, use a CRIT DMG Body. Avoid getting SPD stats to keep the Poet set in full effect.
Since Castorice uses the HP stat, her best Planar Ornament will be the Bone Collection set for the increase in CRIT DMG.
Recommended Stat Values
| Stat | Recommended Value |
|---|---|
| HP% | 7000+ |
| CRIT Rate | Try to get 100% during combat |
| CRIT DMG | +150% |
Getting close to 100% CRIT Rate is the ideal goal on Castorice and should be achievable with the Poet set and CRIT Rate substats.
As for CRIT DMG, you will get a lot of it from the Bone Collection set and ally buffs. 150% CRIT DMG should be enough for Castorice to deal plenty of damage.

 Genius of Brilliant Stars
x4
|
★★★☆☆ - 3rd Best Genius of Brilliant Stars can increase Castorice's Quantum DMG and ignore enemy DEF. Do note that the 4pc. effect will not apply to Castorice's Memosprite. |
| Ornaments | Merits |
 Bone Collection's Serene Demesne
|
★★★★★ - Best Bone Collection's Serene Demesne is Castorice's best ornament as it increases her and her memosprite's CRIT DMG. The effect can be easily activated since Castorice has a lot of HP. |
 Arcadia of Woven Dreams
|
★★★★☆ - 2nd Best Arcadia of Woven Dreams can be used by Castorice for the DMG buff it provides if there are more than 4 allies in combat (Memosprites included). This works if there are two or more other Remembrance characters in the party. |
 The Wondrous BananAmusement Park
|
★★★☆☆ - 3rd Best The Wondrous BananAmusement Park is the third-best option since it can increase Castorice's CRIT DMG as long as her Memosprite is on the field. |
Castorice's Best Light Cones
All Recommended Light Cones
| Light Cone | Why We Recommend It |
|---|---|
|
Make Farewells More Beautiful
|
★★★★★ - Best Make Farewells More Beautiful is Castorice's best-in-slot Light Cone that provides a huge boost in HP and can ignore enemy DEF. This will also advance Castorice in the turn order when her memosprite disappears. |
 To Evernight's Stars
|
★★★★☆ - Great While the energy restoration is negligible, To Evernight's Stars increases Castorice's HP and all memosprites in the party can ignore enemy DEF. |

|
★★★★☆ - Great The Flower Remembers is Castorice's best 4-star Light Cone since this provides CRIT DMG and her Memosprite deals increased CRIT DMG. |

|---|---|
| 1375 | |
| 1270 | |
| 1270 | |
| 1270 | |
| 1270 | |
 Flames Afar
(F2P Option) |
1058 |
As of now, Castorice can only synergize well with four Light Cones in the Remembrance path.
You can use these Light Cones for their high base HP until you get a better-suited Light Cone. Do note that when Castorice equips these Light Cones, the effect will not activate.
Castorice's Eidolons
Recommended Eidolons
| Why We Recommend It | |
|---|---|
| E1 | ★★★★☆ - Great Castorice's kit gets a damage increase depending on how much HP the target enemy has. |
| E2 | ★★★★★ - Amazing Best stopping-point for spenders. Ardent Will offsets Castorice's HP consumption to build up Newbud and she will be in front of the turn order when she summons Netherwing. This synergizes well with Castorice's E1. |
| E4 | ★★☆☆☆ - Okay Increases the Incoming Healing of the party when Castorice is in the party, which helps generate Newbud faster. This is unnecessary if you have a good enough Sustain unit. |
| E6 | ★★★★★ - Amazing Netherwing's attacks now have a Quantum RES PEN and can ignore enemy weaknesses. |
All Eidolon Resonance Effects
| E1 | Snowbound Maiden, Memory to Tomb When the enemy target's current HP is 80%/50% or lower than this unit's Max HP, the DMG dealt with "Boneclaw, Doomdrake's Embrace," "Claw Splits the Veil," "Breath Scorches the Shadow," and "Wings Sweep the Ruins" is 120%/140% of the original DMG. |

Castorice's Trace Priority
| Trace | Priority & Explanation |
|---|---|
| Basic Attack | ★☆☆☆☆ - Lowest Priority Castorice's Basic ATK can be skipped since she uses her Skill more. |

| Ultimate | ★★★★★ - Highest Priority Upgrading Castorice's Ultimate increases the All-Type RES PEN debuff it provides. |
| Talent | ★★★★★ - Highest Priority Upgrading the Talent increases the DMG buff for Castorice and Netherwing when allies lose HP. |
Memosprite Traces
| Trace | Priority & Explanation |
|---|---|
| Memosprite Skill | ★★★★★ - Highest Priority Netherwing will use their Skill a lot to deal damage, so max this out as soon as you can. |
| Memosprite Talent | ★★★★☆ - High Priority This increases the Netherwing Explosion DMG, and healing towards the party. |
Bonus Abilities
| Trace | Priority & Explanation |
|---|---|
| Where The West Wind Dwells | ★★★★★ - Highest Priority This will provide an increase to Netherwing's Memosprite Skill DMG. |
| Inverted Torch | ★★★★★ - Highest Priority Provides an increase to SPD for both Castorice and Netherwing. The SPD boost won't affect the Poet set since it is applied during battle. |
