Release2.0
Black Swan is a Wind Nihility damage-over-time specialist who piles Arcana onto enemies, a DoT that counts as Wind Shear, Bleed, Burn and Shock at once. Since her Novaflare enhancement (Version 4.0), Arcana is only halved after it deals damage, always ignores 20% DEF and splashes adjacent enemies, while her Traces keep enemies' DEF down and give the whole team up to 72% DMG. She is the second pillar of Kafka's DoT teams.

Light Cones
Reforged Remembrance BiS
5★
Signature and best in slot: Effect Hit Rate, ATK and DEF ignore for her DoT. In her premium team, DEF reduction can overcap, which slightly reduces its lead.
Effect Hit Rate +40%; hitting enemies with Wind Shear, Burn, Shock or Bleed grants up to 4 Prophet stacks, each giving +5% ATK and letting DoT ignore 7.2% DEF.
Those Many Springs
5★
Jiaoqiu's signature: lots of Effect Hit Rate and a DMG taken debuff for the whole team; overall team damage is close to her signature.
Effect Hit Rate +60%; attacks can inflict Unarmored (+10% DMG taken), upgraded to Cornered (+14% more) on targets under the wearer's DoT.
Eyes of the Prey
4★
Best 4★ (S5): Effect Hit Rate and a permanent DoT boost.
Effect Hit Rate +20% and DoT +24%.
Why Does the Ocean Sing
5★
Team-oriented option (Hysilens' signature): +10% SPD for attacking allies and a DoT taken debuff. Not ideal for her own damage, and it only reaches full value from her E1.
Effect Hit Rate +40%; debuffs can inflict Enthrallment, raising DoT taken by 5% per wearer debuff (up to 6) and giving attacking allies +10% SPD for 3 turns.
Patience Is All You Need
5★
Kafka's signature (Game8 option): DMG and SPD stacks, plus Erode, an extra Shock-like DoT.
DMG +24% and +4.8% SPD per attack (up to 3 stacks); hits inflict Erode, a Shock-like Lightning DoT equal to 60% of ATK.
It's Showtime
4★
Free option from the Forgotten Hall store: ATK and DMG, but no Effect Hit Rate, so pair it with Pan-Cosmic Commercial Enterprise to reach 120%.
Inflicting a debuff grants +6% DMG for 1 turn (up to 3 stacks), and ATK +20% at 80% Effect Hit Rate or more.

DoT trio
Her most used team: Kafka detonates every DoT, Hysilens applies four DoT types at once to stack Arcana very fast, and Dan Heng • Permansor Terrae shields the team while buffing ATK.

Guide
How to play
How she works (Novaflare kit)
- Arcana (Talent). Every instance of DoT an enemy takes has a 65% base chance to add 1 Arcana stack. At the start of the enemy's turn, Arcana deals Wind DoT (240% ATK + 12% per stack, counted up to 50 stacks), ignores 20% DEF and hits adjacent enemies for 180% ATK; then the stacks are halved instead of reset. Stacks can overflow past 50 (the excess is removed after the damage).
- Viscera's Disquiet (A2). Every enemy she hits has a 65% base chance to receive 5 Arcana stacks.
- Goblet's Dredges (A4). Enemies entering combat get 1 Arcana and her Skill's DEF reduction; her Basic ATK and Ultimate also apply that DEF reduction.
- Skill. Blast attack that lowers DEF by 20.8% for 3 turns.
- Ultimate: Bliss of Otherworld's Embrace (120 Energy). Inflicts Epiphany on all enemies: for 2 turns, they take 25% more DMG, each Arcana stack applied has a 50% fixed chance to be doubled, and Arcana is no longer halved after dealing damage.
- Candleflame's Portent (A6). All allies deal extra DMG equal to 60% of her Effect Hit Rate, up to 72% at 120% Effect Hit Rate.
Rotation
- Use her Technique before combat to start with Arcana on every enemy.
- Open with her Skill to lower DEF, then keep Epiphany up with her Ultimate as often as possible.
- Alternate Skill and Basic ATK depending on your Skill Points: both her Basic ATK and her Ultimate refresh the DEF reduction thanks to her A4.
- Let Kafka (and Hysilens) detonate and multiply DoT instances: each one stacks more Arcana.
Tips
- 120% Effect Hit Rate is the key stat: it maxes out the team DMG bonus of her A6.
- Kafka remains her essential partner; Hysilens completes the best DoT trio.
- Since Arcana counts as every DoT type, she also enables Type-specific DoT detonations of other characters.
Strengths
- Very high, consistent DoT damage that ignores part of the enemies' DEF
- Brings DEF reduction, a DMG taken debuff and up to 72% DMG to the whole team
- Ramps up very quickly and stays ramped up now that Arcana is only halved
- Arcana counts as Wind Shear, Bleed, Burn and Shock for DoT synergies
- Excellent in AoE and still strong in single-target fights
Weaknesses
- Still needs Kafka (and ideally Hysilens) to reach her full potential
- Needs heavy investment, including 120% Effect Hit Rate, to max out her A6
Notable dupes · Eidolon
E1
Big upgrade
Enemies lose 25% Wind, Physical, Fire and Lightning RES, since Arcana always counts as all four DoTs. The recommended stopping point.
E2
Solid upgrade
Enemies entering combat receive 30 Arcana stacks: much faster ramp-up, especially in Pure Fiction.
E4
Optional
Epiphany's DMG taken bonus rises to 45%, and she regenerates 8 Energy at the start of each Epiphany-afflicted enemy's turn or when it is defeated.
E6
Optional
Arcana cap raised to 80, her Arcana applications are doubled and her teammates' attacks can also apply Arcana.
