Note for beginners

Castorice has no clear weak point based on current data, but needs the right build (see the Build section below) to reach full potential.

Should you pull Castorice?

Castorice is a monster HP-scaling AoE main DPS, sitting around T0 in nearly every mode. Pull if you want an easy-to-play, self-fueling carry that clears both Memory of Chaos and Pure Fiction. Skip if your DPS slots are full or you lack a strong healer.

Pros
  • Enormous HP-scaling AoE with self-sufficient energy
  • Near-T0 in Memory of Chaos and Pure Fiction
  • Doesn't need DEF/SPD tuning, easy to gear
  • Netherwing plays freely with no energy anxiety
Cons
  • Consumes team HP, so a strong healer is mandatory
  • Signature cone and relics are a bit niche for F2P
  • Team is Remembrance-centric and less flexible

How to play

Open by using her Skill to build Newbud and spend HP, then summon the Netherwing memosprite and unleash its attack chain for big AoE bursts.

Keep the dragon out while Newbud lasts, then repeat: stack HP, summon, dump damage. Keep your SPD low so the Poet set always gives max CRIT.

Eidolons

How far to invest, which milestones matter

E0 is fully complete and very strong, no verticals needed. If you have spare resources, E1 is the sweet spot and E2 adds meaningful damage. Her signature cone isn't required but noticeably raises the ceiling.

E1
Snowbound Maiden, Memory to Tomb★★★★☆
When the enemy target's current HP is 80%/50% of Max HP or lower, the DMG dealt to it by "Boneclaw, Doomdrake's Embrace," "Claw Splits the Veil," "Breath Scorches the Shadow," and "Wings Sweep the Ruins" is 120%/140% of the original DMG respectively.
Significantly boosts Netherwing's damage against low-HP targets (80%/50% threshold), greatly speeding up enemy takedowns.

E2
Crown on Wings of Bloom★★★☆☆
After summoning the memosprite Netherwing, Castorice gains 2 stack(s) of "Ardent Will." "Ardent Will" can stack up to 2 time(s) and can be used to offset the HP cost of Netherwing's Memosprite Skill, "Breath Scorches the Shadow" and advance Castorice's action by 100%. When using the next Enhanced Skill, Castorice gains "Newbud" by an amount equal to 30% of max "Newbud."
Grants 2 stacks of "Ardent Will" to offset the HP cost of Netherwing's skill, improving sustainability without directly boosting damage.

Castorice FAQ

What is the best Light Cone for Castorice?

The best Light Cone for Castorice is Make Farewells More Beautiful (top pick). See F2P options in the Light Cones section above.

Is Castorice worth pulling?

Castorice is a monster HP-scaling AoE main DPS, sitting around T0 in nearly every mode. Pull if you want an easy-to-play, self-fueling carry that clears both Memory of Chaos and Pure Fiction. Skip if your DPS slots are full or you lack a strong healer.

What is the best team for Castorice?

Core team: Castorice + Remembrance Trailblazer (memosprite buffer) + Tribbie or Cyrene + Hyacine as healer. Dual-carry adds March 7th as a sub-DPS. Budget line: Pela for def shred plus Gallagher to heal the HP drain.

What materials does Castorice need to reach max Ascension?

See the full Ascension Materials list above, pulled directly from the latest game data.

How to read this build page

Every character build page has these parts: recommended Light Cone/Relic sets and stat table, a Trace/skill leveling order, Eidolon milestones worth considering, and a reference SPD threshold. Read them in that order — gear tells you "what to use", Traces tell you "what to level first", Eidolon tells you "is it worth pulling dupes", SPD tells you "how fast you need to be to keep the rotation on time". The section below explains how to read each part and applies the same way to every character on the site — check the exact numbers in the table above this section, since community sources sometimes differ by a few points.

Why the Light Cone and Relic picks make sense

Most characters have a "signature" Light Cone built for their exact role, plus a few cheaper substitutes from the standard banner or easy-to-get 3-4★ cones. Missing the signature isn't a dead end — most characters keep most of their power with a well-matched substitute, typically losing somewhere between a few percent and roughly a fifth of total damage depending on the setup, per most public comparisons.

  • Relic sets (2pc+2pc or 4pc) are picked for the set effect that fits that character's role (single-target DPS, AoE, shield/healing support, Break damage, and so on).
  • Main stats per slot (Body/Feet/Sphere/Rope) and substats follow a priority that changes by role: DPS roles usually chase CRIT Rate/CRIT DMG before ATK%; Break-focused roles prioritize Break Effect; support/healing roles often value Effect Hit/RES or Outgoing Healing over pure CRIT.

These weights differ per character and can shift slightly between ranking sources — follow the exact priority table above rather than applying one formula to every role.

Trace/skill leveling order by role (a general guideline, not a fixed rule)

There's no single order that's correct for every character, and community sources sometimes disagree depending on the team the character is used in — but the general pattern by role is:

  • DPS: level whichever skill (Skill or Ultimate) carries most of the damage for that character first, with Basic ATK usually last if it isn't the main damage source.
  • Support/Buffer: prioritize Traces that boost buff strength or the skill that applies the effect over Basic ATK, since this role's value comes from lifting the team rather than personal damage.
  • Healer/Shielder: prioritize the main healing or shield skill first, since that is the reason the team runs this character.
  • Break/CC: prioritize whichever skill contributes the most Toughness Damage, since the Break/Weakness Break window is where the team dumps damage.

Major Traces unlock at fixed ascension levels in-game, not by choice — but which one to level first (when resources are limited) should follow the role priority above. Since the exact order can differ between ranking sources, check the specific recommendation in the table above for this character.

Eidolons: how far E0 gets you, and which milestone is worth considering

General rule: most characters at E0 (no duplicates) already handle most content, even 5-star characters. Eidolons are a duplicate-fueled upgrade system — higher levels cost more resources for a smaller power gain, and the actual gain varies a lot per character (some barely change role at E0, others shift how they're played at a specific level). The milestones most often cited by the community tend to sit at E1, E2, or E6 depending on the character — but none of these are required to clear the game's content. Check the Eidolon section in the table above for this character's specific milestone and gain; if sources disagree on how to rate a milestone, trust the in-game effect description over a pre-set percentage number.

How to think about SPD breakpoints

SPD (Speed) controls how often a character acts in the turn order — higher SPD means denser actions, and for some roles (especially support/healing that need to buff or heal before the team gets hit) hitting the right SPD "breakpoint" matters more than the raw SPD number. Values like 101 or 134 SPD are often cited as community-common breakpoints (letting a character act again before or after a specific point in certain team setups) — this is crowd-verified action-gauge math, not an official fixed number the game states for every situation. The right breakpoint also depends on the team and allies' SPD, so treat the SPD suggestion in the table above as a starting point to adjust from, not a mandatory target.

Where to dig deeper

This section only teaches you how to read the page — for deeper comparisons, use the dedicated tools:

  • Teams for full in-game comps with rotation order.
  • Relic score to check how your current gear scores against the benchmark.
