Note for beginners

Black Swan 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 Black Swan?

If you love the DoT 'plant the poison and watch enemies melt' playstyle, Black Swan is the #1 piece — especially if you already own Kafka.

Skip her if you're not building any DoT team.

Pros
  • Explosive DoT damage that scales with more enemies
  • Massive team-wide DEF shred and RES shred
  • Post-4.0 rework plays smoothly with no slow ramp
  • Perfect synergy with Kafka and Hysilens
Cons
  • Weaker against single bosses than direct DPS
  • Relies on a detonator teammate for peak output
  • Grinding enough Effect Hit Rate is tedious
  • Underwhelming in Apocalyptic Shadow (favors break/burst)

How to play

Open with Skill on the primary target to spread Arcana and apply DEF shred, then fire Ultimate as soon as you have energy to enter Epiphany (which now applies 25% DoT vulnerability permanently after 4.0).

On later turns keep skilling to spread Arcana wide and let Kafka detonate all DoTs.

Best teams for Black Swan

Kafka + Black Swan is the core: stack DoTs, then detonate on repeat; Ruan Mei or Hysilens amplifies, Huohuo/Aventurine keeps everyone alive. The F2P SampoAstaNatasha line still clears standard content.

Eidolons

How far to invest, which milestones matter

E0 already delivers ~85-90% of her power, so play her freely. E1 is one of the highest-value Eidolons in the game: a team-wide 25% Elemental RES shred on DoT-afflicted enemies. E2 is strong but a luxury.

Skills & Traces

What to level first — tap each skill for details

Skill Leveling Priority

Talent ★★★★★ Talent deals the core Wind DoT at 300% ATK scaling with Arcana stacks, making it Black Swan's main damage source.
Skill ★★★★★ Skill hits an AoE, applies Arcana at 100% base chance and shreds DEF, directly amplifying the Talent's DoT so it should be leveled early.
Ultimate ★★★★☆ Ultimate inflicts Epiphany, boosting DMG taken by 30% and converting Arcana into multiple simultaneous DoTs, an important buff but limited to 2 turns.
Basic ATK ★★☆☆☆ Basic ATK deals low damage and has a lower chance to apply Arcana, so it remains the lowest leveling priority as usual.
Trace priority: A4 > A2 > A6 Eidolon priority: E1 > E4 > E2 > E6 > E3 = E5

Attack

Attacks an enemy, and after entering combat, reduces their Toughness of the corresponding Type.

From Façade to Vérité
Technique Enhance

After this Technique is used, there is a 150% base chance for each enemy to be inflicted with 1 stack of Arcana at the start of the next battle. For each successful application of Arcana on a target, inflicts another stack of Arcana on the same target. This process repeats until Arcana fails to be inflicted on this target. For each successive application of Arcana on a target, its base chance of success is equal to 50% of the base chance of the previous successful infliction of Arcana on that target.

Black Swan FAQ

What is the best Light Cone for Black Swan?

The best Light Cone for Black Swan is Reforged Remembrance (top pick). See F2P options in the Light Cones section above.

Is Black Swan worth pulling?

If you love the DoT 'plant the poison and watch enemies melt' playstyle, Black Swan is the #1 piece — especially if you already own Kafka. Skip her if you're not building any DoT team.

What is the best team for Black Swan?

Kafka + Black Swan is the core: stack DoTs, then detonate on repeat; Ruan Mei or Hysilens amplifies, Huohuo/Aventurine keeps everyone alive. The F2P Sampo–Asta–Natasha line still clears standard content.

How much Energy does Black Swan's Ultimate cost?

Black Swan's Ultimate costs 120 Energy. See the Skills section above for the Energy gain and Break DMG of every skill.

What materials does Black Swan need to reach max Ascension?

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.
