Introduction

Black Swan is a DPS character capable of inflicting the enemy with "Arcana" through various means. "Arcana" is a unique form of DoT. Black Swan can trigger various additional effects based on the number of "Arcana" stacks on the enemy target.


Skills Overview

Basic Attack - Percipience, Silent Dawn

Deals Wind DMG equal to 30-78% of Black Swan's ATK to a single target enemy, with a 50-74% base chance of inflicting 1 stack of Arcana. And if the hit target currently has Wind Shear, Bleed, Burn, or Shock applied to them, each respectively has a 50-74% base chance of inflicting 1 extra stack of Arcana onto the enemy.


Skill - Decadence, False Twilight

Deals Wind DMG equal to 45-112.5% of Black Swan's ATK to a single target enemy and any adjacent targets. At the same time, there is a 100% base chance of inflicting 1 stack of Arcana on the target enemy and the adjacent targets. And there is a 100% base chance of reducing the DEF of the target enemy and the adjacent targets by 14.8-23.8%, lasting for 3 turn(s).


Ultimate - Bliss of Otherworld's Embrace

Inflicts Epiphany on all enemies for 2 turn(s).
Enemies affected by Epiphany take 15-30% more DMG in their turn, and their Arcana effect is regarded as Wind Shear, Bleed, Burn, and Shock effects. In addition, when their Arcana effect is triggered at the beginning of the next turn, the Arcana stacks are not reset. The stack non-reset effect can be triggered up to 1 time(s) in Epiphany's duration, and its charges are replenished when Epiphany is applied again.


Talent - Loom of Fate's Caprice

Every time an enemy target receives DoT at the start of each turn, there is a 50-72.5% base chance for it to be inflicted with Arcana.
While afflicted with Arcana, enemy targets receive Wind DoT equal to 96-300% of Black Swan's ATK at the start of each turn. Each stack of Arcana increases this DoT DMG multiplier by 4.8-15%. Then Arcana resets to 1 stack. Arcana can stack up to 50 times.

Only when Arcana causes DMG at the start of an enemy target's turn, Black Swan triggers additional effects based on the number of Arcana stacks inflicted on the target:
When there are 3 or more Arcana stacks, deals Wind DoT equal to 72-225% of Black Swan's ATK to adjacent targets, with a 50-72.5% base chance of inflicting 1 stack of Arcana on adjacent targets.
When there are 7 or more Arcana stacks, enables the current DoT dealt this time to ignore 20% of the target's and adjacent targets' DEF.


Technique - From Façade to Vérité

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.
