Castorice's Best Light Cone

Listed below are the Light Cones we recommend for Castorice.

Make Farewells More Beautiful

Increases the wearer's Max HP by 30.0 / 37.5 / 45.0 / 52.5 / 60.0%. 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 30.0 / 35.0 / 40.0 / 45.0 / 50.0% 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 12.0 / 15.0 / 18.0 / 21.0 / 24.0%. This effect can only trigger up to 1 time, and the trigger count resets every time the wearer uses Ultimate.

is Castorice's signature and strongest weapon currently in the game. This Light Cone allows Castorice and her Memosprite Netherwing to ignore enemy DEF when they lose HP. This Light Cone additionally grants Castorice and her Memosprite additional HP based on max HP. When Netherwing retreats Castorice's action is also advanced.

To Evernight's Stars

Increases the wearer's Max HP by 30.0 / 37.5 / 45.0 / 52.5 / 60.0%. When the wearer's memosprite uses an ability, the wearer gains "Noctis." While the wearer has "Noctis," the DMG dealt by all ally memosprites ignores 20.0 / 22.5 / 25.0 / 27.5 / 30.0% of the targets' DEF. Increases the DMG dealt by the wearer and their memosprite by 30.0 / 37.5 / 45.0 / 52.5 / 60.0%. When the wearer's memosprite disappears, the wearer recovers 8 / 10 / 12 / 14 / 16 Energy. Effects of the same type cannot stack.

This is another great 5-star Light Cone for Castorice. Similarly to her signature, it increases Castorice's max HP. Rather than losing HP to ignore enemy DEF, when Netherwing uses an ability the DMG dealt by all allied memosprites ignores a portion of the enemy DEF as well as increases the DMG dealt by Castorice and Netherwing. As Netherwing retreats, Castorice will also gain energy in this way.

The Flower Remembers

Increases the wearer's CRIT DMG by 24.0 / 28.0 / 32.0 / 36.0 / 40.0%. The CRIT DMG dealt by the wearer's memosprite increases by 24.0 / 30.0 / 36.0 / 42.0 / 48.0%.

Sources: Nameless Glory

This 4-star Light Cone can be obtained on the Battle Pass. This is another good choice for Castorice as it enhances her CRIT DMG as well as her memosprite's CRIT DMG allowing them to make even stronger ATKs on top of her already powerful ATKs.

Sweat Now, Cry Less

Increases the wearer's CRIT Rate by 12.0 / 14.0 / 16.0 / 18.0 / 20.0%. When the wearer's memosprite is on the field, increases the DMG dealt by the wearer and their memosprite by 24.0 / 27.0 / 30.0 / 33.0 / 36.0%.

Sources: Nameless Glory

This 4-star Light Cone enhances Castorice's CRIT Rate as well as increases her own and her Memosprite Netherwing's DMG when they are on the field.

The Story's Next Page

Increases the wearer's Max HP by 16.0 / 20.0 / 24.0 / 28.0 / 32.0%. After the wearer's memosprite attacks, the Outgoing Healing of the wearer and their memosprite increases by 12.0 / 15.0 / 18.0 / 21.0 / 24.0%, lasting for 1 turn(s).

Sources: Event Warp (limited), Stellar Warp

Victory In a Blink

Increases the wearer's CRIT DMG by 12.0 / 15.0 / 18.0 / 21.0 / 24.0%. When the wearer's memosprite uses an ability on an ally target, increases the DMG dealt by all ally targets by 8.0 / 10.0 / 12.0 / 14.0 / 16.0%, lasting for 3 turn(s).

Sources: Forgotten Hall Store

Flames Afar

When the wearer's cumulative HP loss during one attack exceeds 25.0% of their Max HP, or if the amount of their own HP consumed at one time is greater than 25.0% of their Max HP, immediately heals the wearer for 15.0% of their Max HP, and at the same time, increases the DMG they deal by 25.0 / 31.3 / 37.5 / 43.8 / 50.0% for 2 turn(s). This effect can only be triggered once every 3 turn(s).

is simply an example Light Cone. But any with a base HP of 1058 or higher will perform similarly, if not better, than at S5. These Light Cones cannot have the effects activated as Castorice does not belong to that path, these simply act as "stat-sticks".
Other Light Cones with more HP can perform similarly to .

Best Relics and Planar Ornaments for Castorice

Best Relics for Castorice

These are the best Relic sets for Castorice.

Poet of Mourning Collapse

2-Piece Set: Increases Quantum DMG by 10.0%.

4-Piece Set: Decreases the wearer's SPD by 8.0%. Before entering battle, if the wearer's SPD is lower than 110/95, increases the wearer's CRIT Rate by 20.0%/32.0%. This effect applies to the wearer's memosprite at the same time.

is Castorice's best relic set to build. Castorice has a low base SPD already and this set reduces her base SPD further which then provides her with a high amount of increased CRIT Rate which is great for her, as it makes her already strong hits even stronger. Not only does it increase her own CRIT Rate but this also applies to her Memosprite.

Scholar Lost in Erudition

2-Piece Set: Increases CRIT Rate by 8.0%.

4-Piece Set: Increases DMG dealt by Skill and Ultimate by 20.0%. After using Ultimate, additionally increases the DMG dealt by the next Skill by 25.0%.

This 2-piece set is another good choice for Castorice as it increases the number of times she can CRIT during battle, making her stronger overall.

Wavestrider Captain

2-Piece Set: Increases CRIT DMG by 16.0%.

4-Piece Set: When the wearer becomes the target of another ally target's ability, gains 1 stack of "Help," stacking up to 2 time(s). If there are 2 stack(s) of "Help" when the wearer uses their Ultimate, consumes all "Help" to increase the wearer's ATK by 48.0% for 1 turn(s).

This 2-piece set is a good option for Castorice as it increases her CRIT DMG.

Longevous Disciple

2-Piece Set: Increases Max HP by 12.0%.

4-Piece Set: When the wearer is hit or has their HP consumed by an ally or themselves, their CRIT Rate increases by 8.0% for 2 turn(s) and up to 2 stacks.

This 2-piece set increases Castorice's max HP which is great as the more HP Castorice has, the more DMG her memosprite will deal during its turn.

Best Planar Ornaments

Bone Collection's Serene Demesne

2-Piece Set: Increases the wearer's Max HP by 12.0%. When the wearer's Max HP is 5000 or higher, increases the wearer's and their memosprite's CRIT DMG by 28.0%.

This Planar set is one of the best options for Castorice as it increases her max HP, therefore increasing the max DMG her memosprite deals, as well as her own and her memosprite's CRIT DMG when her HP is 5000 or more. Due to Castorice already needing a high amount of HP to get the most DMG from her Memosprite achieving this is easy.

Arcadia of Woven Dreams

2-Piece Set: When the number of ally targets on the field is not equal to 4, for every 1 additional/missing ally target, increases the DMG dealt by the wearer and their memosprite by 9.0%/12.0%, stacking up to 4/3 time(s).

Another strong choice for Castorice when it comes to dealing an increased amount of DMG. When there's more or less than 4 allies in battle, Castorice and her Memosprite gain additional DMG which can stack up to 3-4 times.

Castorice Build Comments

Character Explanation Character Role

Character Explanation

Castorice is a strong DPS character to add to your team setup. Castorice focuses on using her Memosprite "Netherwing" to deal huge amounts of AoE DMG. Castorice doesn't use skill points in order to use her Ultimate but rather has a charge system called "Newbud". As Allies take DMG or receive healing, Newbud is accumulated until it reaches 100% and Netherwing is summoned to the field. When this happens, Netherwing reduces enemy All Type RES and boosts all allies' DMG by 10% for 3 turns. In addition to this, when Netherwing has entered the field, Castorice advances her action by 100%.

Netherwing does not take DMG directly from enemies but rather takes excess DMG from allies that would otherwise reduce their HP below 1%. The excess DMG taken by Netherwing is increased by 500% of its original value, which can therefore reduce Netherwing's HP to 0 making it leave the field. If Netherwing's HP is 25% or less, this will trigger a finishing burst "Wings Sweep the Ruins" which will deal 6 instances of Quantum DMG equal to 40% of Castorice's max HP in addition to restoring allies' HP by 800.

Netherwing has 2 main attacks - "Claw Splits the Veil" and "Breath Scorches the Shadow". Claw deals 40% of Castorice's max HP in an AoE while the Breath attack is generally the stronger attack, consuming 25% of Netherwing's HP and dealing up to 24% of Castorice's max HP to each enemy. As you progress through each level of this attack by continuously holding down the trigger, this attack deals an increased amount of damage. If all of Netherwing's HP is consumed, one final burst of damage will be triggered.

As an additional backup when it comes to providing a line of defence in any fight, Netherwing can use their talent "Mooncocoon Shrouds the Form" to take damage in place of an ally about to die allowing the ally to take another turn and consume HP before they are permanently removed from the fight. This can be useful in instances where you may have made a miscalculation during a fight causing your character to take too much damage causing them to lose all HP.

Character Role

Castorice is a solid DPS character who can provide a small amount of defence and healing for her team but primarily focuses on dealing large amounts of damage through the use of her ultimate which summons her memosprite.

Castorice's Best Eidolons

When it comes to selecting which Eidolons are the most important to focus on, her E2 and E6 are notably the strongest and most beneficial.

Below is a brief overview of the key Eidolons that enhance her performance:

E1: Boosts damage based on the enemy's HP, giving a solid overall increase.
E2: Helps manage HP consumption, speeds up Newbud generation and improves turn order. Works especially well with E1.
E4: Increases team healing and helps generate Newbud faster, but not essential if you already have a strong healer.
E6: Major power increase, attacks gain Quantum RES PEN and can ignore enemy weaknesses.

Overall, E2 is the best stopping point for most players, while E6 offers the biggest endgame upgrade.
