Honkai Star Rail Black Swan's kit

Black Swan is a 5-Star Wind character of The Nihility path who is best at applying DOT (damage over time) effects, while also lowering the defence of enemies, and increasing the damage they receive.

All of the percentages mentioned below are based on Level 1 Traces.

Here's a summary of Black Swan's kit in Honkai Star Rail:

• Element: Wind.
• Path: The Nihility.
• Rarity: 5-Star.
• Basic Attack: Percipience, Silent Dawn (Deals Wind damage equal to 30% of Black Swan's attack to a single enemy, with a 50% base chance of inflicting one stack of Arcana. If the hit enemy also has Wind Shear, Bleed, Burn, or Shock applied to them, each of these DOT's will have a 50% base chance of additionally applying one stack of Arcana on the enemy).
• Skill: Decadence, False Twilight (Deals Wind damage equal to 45% of Black Swan's attack to a single enemy and adjacent targets, with a 100% base chance to inflict one stack of Arcana to the attacked enemies and a 100% base chance to lower the attacked enemies' defence by 14.8%, lasting for three turns).



• Ultimate: Bliss of Otherworld's Embrace (Deals Wind damage equal to 72% of Black Swan's attack to all enemies, and inflicts Epiphany on them for two turns. Enemies affected by Epiphany take 15% more damage on their turn, and their Arcana effect is regarded as Wind Shear, Bleed, Burn, and Shock effects. Additionally, when their Arcana effect is triggered at the beginning of the next turn, the Arcana stacks are not reset. This stack non-reset effect can be triggered up to one time during the Epiphany duration, and its charges are replenished when Epiphany is applied again).
• Talent (passive ability): Loom of Fate's Caprice (Every time an enemy target receives a DOT at the start of their turn, there is a 50% base chance that the enemy is inflicted with Arcana. While afflicted with Arcana, enemy targets receive Wind DOT equal to 96% of Black Swan's attack at the start of each turn. Each stack of Arcana increases this DOT damage multiplier by 4.8%, then Arcana resets to one stack. Arcana can stack up to 50 times. Black Swan triggers additional effects based on the number of Arcana stacks inflicted on the target, but only when Arcana deals damage at the start of an enemy target's turn. The additional effects deal Wind DOT equal to 72% of Black Swan's attack to adjacent targets when they have three or more Arcana stacks, with a 50% base chance of inflicting one stack of Arcana on adjacent targets. Also, when they have seven or more Arcana stacks, the current DOT dealt after this ignores 20% of the target's defence and adjacent targets' defence).
• Technique (overworld ability): From Façade to Vérité (At the start of the next battle, there is a 150% base chance to inflict one stack of Arcana to all enemies. One additional stack of Arcana is applied to an enemy for each successful application of Arcana, repeating 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).
• Bonus Trace 1: Viscera's Disquiet (After using her Skill to hit a single target enemy that has Wind Shear, Bleed, Burn, or Shock, there is a 65% base chance to additionally inflicting one stack of Arcana for each type of DOT on an enemy).
• Bonus Trace 2: Goblet's Dredges (There is a 65% base chance to inflict one tack of Arcana when a target enters battle. Every time an enemy receives DOT during a single attack by an ally, there is a 65% base chance for the target to be inflicted with one stack of Arcana, stacking up to three times during one single attack).
• Bonus Trace 3: Candleflame's Portent (Increases Black Swan's damage dealt by an amount equal to 60% of her Effect Hit Rate, up to a maximum damage increase of 72%).
