Should you pull Cerydra?

Cerydra is a top-tier single-target buffer for DPS units that lean on their Skill. Pull if you own Phainon or Anaxa; skip if your roster is all basic/ult-based DPS or you want a flexible team-wide support.

Pros
  • Huge Skill CRIT DMG + RES PEN buff for one carry
  • Grants the carry extra SP-free Skill actions
  • Trace self-hits the SPD breakpoint and cleanses CC
Cons
  • Single-target buff makes her very team-dependent
  • Only shines with Skill-reliant carries
  • Hitting 4000 ATK demands heavy relic investment
How to play

Each turn cast Skill on your main carry to grant 'Military Merit'; reaching 6 Charge upgrades it to 'Peerage' (+72% Skill CRIT DMG, +10% all-type RES PEN, cleanses CC). Fire Ultimate early for extra Charge and keep Skill locked on the same carry every round.

Stat targets

Aim for ~4000 ATK to max the CRIT DMG buff from her trace; ~134-140 SPD is enough (she self-reaches the 160 in-combat breakpoint); enough Energy Regen to Ult every 2 turns. She needs NO CRIT or EHR.

Best teams for Cerydra

Her two best cores are Phainon + Cyrene and Anaxa + Tribbie, since both carries spam Skill and soak her buffs fully; always add a sustain like Aventurine. Feixiao works but is less optimal as she rarely uses Skill.

Eidolons
How far to invest, which milestones matter

E0 (E1/E2 rất mạnh) — E0 is fully functional and unlocks her whole kit. E1 (DEF ignore) and E2 (large DMG boost) are strong if you have spare resources; E6 is for whales only.

E1
Seize the Crowns of All★★★★☆
The character with "Military Merit" ignores 16% of the targets' DEF when dealing DMG. If "Military Merit" has been upgraded to "Peerage," then the character additionally ignores 20% of the targets' DEF when dealing Skill DMG. When Cerydra uses her Skill, regenerates 2 Energy for the designated ally target.
The Military Merit holder ignores 16% DEF on damage dealt, plus an extra 20% DEF PEN on Skill damage once upgraded to Peerage, meaningfully boosting real damage output.
E2
Forge the Dreams of Many★★★★★
The character with "Military Merit" deals 40% increased DMG. While a teammate on the field has "Military Merit," Cerydra's DMG dealt increases by 160%.
The Military Merit holder deals 40% more damage, and Cerydra herself gains a massive 160% damage increase while a teammate holds Military Merit — a huge team-wide damage spike.
E3

Skills & Traces
What to level first — tap each skill for details
Skill Leveling Priority
Talent ★★★★★ Talent is the core power source: the ATK buff and bonus Wind Additional DMG granted to the ally holding "Military Merit" both scale with Talent level.
Ultimate ★★★★☆ Ultimate is her main AoE nuke with a level-scaling 288% ATK multiplier and can also grant "Military Merit" if no one has it yet, making it worth leveling early.
Skill ★★★☆☆ Skill applies "Military Merit" and builds Charge to sustain the buff loop, so it needs decent levels but isn't her main damage source.
Basic ATK ★☆☆☆☆ Basic ATK only deals plain single-target damage and is, as usual, the lowest leveling priority.
Trace priority: A4 > A6 > A2 Eidolon priority: E2 = E6 > E4 > E1 > E3 = E5

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.
