Black Swan Stats

Is Black Swan Good?

Black Swan is one of the strongest DoT units in-game whose game plan is to simply apply Arcana onto enemies. Black Swan's DoT becomes a lot stronger the more Arcana stacks an enemy has accumulated.

Pull for Black Swan if you want to give a huge upgrade to your DoT teams, especially if you have Kafka.

Black Swan's Best Builds

DoT DPS Build

Black Swan needs at least 120% Effect Hit Rate to max out her DMG buff from her Third Bonus Ability. You can equip the Firmament Frontline: Glamoth instead if you have managed to get enough Effect Hit Rate through substats.

Black Swan's DoTs scale on the ATK stat and SPD is useful for letting her act sooner and take more turns in one cycle. If you have Ruan Mei in your party, use an ATK% Sphere on Black Swan as the former already provides a huge buff to the latter's DMG.

Recommended Stat Values

Stat	Recommended Value
Effect Hit Rate	120%
ATK	3000 or above
SPD	135 - 160 SPD should be higher than Kafka's

Black Swan's Best Teams

Black Swan F2P Team (Free to Play)

Sub-DPS	DPS	Support	Healer
Black Swan	Serval	Asta	Natasha

Black Swan will go in tandem with Serval as the two DPS characters in the party. Serval can also provide Shock DoTs with her kit.

Asta is the best free-to-play Support for Black Swan thanks to her SPD and ATK buffs for the entire party.

Black Swan DoT Team

Sub-DPS	DPS	Support	Healer
Black Swan	Kafka	Ruan Mei	Huohuo

Black Swan shines in DoT-centric teams with Kafka as the Main DPS who can trigger her DoTs.

Ruan Mei can increase the party's Break Efficiency and delay the enemies' recovery from Break, which results in them taking in more DoTs before they manage to attack.

Relic List & Guide

Black Swan's Best Light Cones

All Recommended Light Cones

Light Cone	Why We Recommend It
Reforged Remembrance	★★★★★ - Best Reforged Remembrance is the best for Black Swan since she can fully stack Prophet every time she uses her Ultimate. The increased Effect Hit Rate, ATK, and DEF ignore also improve her ability to stick Arcana onto the enemy and increase her DMG significantly.
Eyes of the Prey	★★★★☆ - Great Eyes of the Prey is also a great option for Black Swan since it provides Effect Hit Rate and boosts DoT by a certain amount, which her Arcana debuff benefits from.
Patience Is All You Need	★★★★☆ - Great Patience Is All You Need is also a great Light Cone option for Black Swan since it increases her DMG and SPD. It also gives her access to Erode, which is another debuff that gives Lightning DoT.
Those Many Springs	★★★★☆ - Great Those Many Springs can provide Black Swan with a lot of Effect Hit Rate and increase the DMG taken by enemies. This may decrease Black Swan's personal damage.
Good Night and Sleep Well	★★★☆☆ - Good Good Night and Sleep Well is a great 4-Star Light Cone for Black Swan since it gives her a stacking DMG boost for every debuff the enemy has.
Before the Tutorial Mission Starts	★★★☆☆ - Good Before the Tutorial Mission Starts is a good Light Cone for Black Swan since it increases her Effect Hit Rate and also regenerates her Energy when she attacks enemies with reduced DEF. This is easily achievable since her Skill can reduce enemy DEF.

Black Swan's Gameplay Guide

DoTs Apply Arcana onto Enemies

When Black Swan is in the party, there is a base chance for enemies to receive the Arcana debuff after getting hit with a DoT. Arcana deals Wind DMG to an enemy at the start of their turn.

Arcana Bonus Effects

Arcana can also provide additional effects depending on the number of Arcana stacks an enemy has.

No. of Stacks	Effect
3+	Deals Wind DoT to adjacent targets and has a base chance of applying 1 bonus Arcana stack on Adjacent Targets
7+	Arcana DoTs ignore a set percentage of the target and adjacent targets' DEF.

Basic ATKs Apply Extra Arcana Stacks

Black Swan's Basic ATKs can also apply Arcana stacks onto enemies. If the enemy is inflicted with Wind Shear, Bleed, Burn, or Shock DoTs, each respectively has a chance of applying an extra Arcana stack.

Skill can Apply Arcana and Reduce DEF

Black Swan's Skill deals Wind DMG to a single enemy and adjacent targets and has a chance to apply Arcana and DEF Reduction to the attacked enemies.

Ultimate Inflicts Epiphany on All Enemies

Black Swan's Ultimate will deal Wind DMG to all enemies and apply the Epiphany effect onto them. Enemies affected with Epiphany deal increased DMG on their turn and the Arcana stacks will count as Wind Shear, Bleed, Burn, and Shock.

On top of that, if Arcana is triggered at the start of an enemy's turn, the stacks will not reset.

Technique Applies Arcana at the Start of Combat

After using Black Swan's Technique, enemies have a base chance to be inflicted with Arcana repeatedly until it fails to be applied.

Black Swan's Trace Priority

Combat Traces

Trace	Priority & Explanation
Basic Attack	★★★☆☆ - Medium Priority Black Swan's Basic ATKs should be upgraded last since it contributes the least DMG given to an enemy. It's still important to upgrade this Trace to increase the chances of applying more Arcana stacks.
Skill	★★★★☆ - High Priority Upgrading Black Swan's Skill will strengthen the DEF debuff applied to enemies.
Ultimate	★★★★☆ - High Priority Increases the DMG taken by enemies at the start of their turn, which lets them take more DoT DMG in the process.
Talent	★★★★★ - Highest Priority Upgrading Black Swan's Talent simply increases her Arcana DMG, which is an essential part of her kit.

Bonus Abilities

Trace	Priority & Explanation
Viscera's Disquiet	★★★★★ - Highest Priority This allows Black Swan to inflict an extra Arcana stack with her Skill on enemies affected with other DoTs.
Goblet's Dredges	★★★★★ - Highest Priority Enemies now have a chance to be inflicted with Arcana upon entering combat. Enemies can also gain Arcana stacks simply by receiving a DoT from an allied unit.
Candleflame's Portent	★★★★★ - Highest Priority This Bonus Ability significantly increases Black Swan's overall DMG based on the current amount of Effect Hit Rate she has.
