Introductions
Welcome to our team composition guide for Black Swan in Honkai: Star Rail. In this guide, we'll explore the best teams to build for Black Swan, including recommended team compositions, character synergies and everything you need to know to build the best Black Swan teams.
Best Synergies for Black Swan
Kafka is the best DoT Support in the game and works excellently with Black Swan. Kafka will continually trigger DoT damage on enemies which increases their Arcana stacks rapidly as well as causing it to do damage. When combined this ends up boosting Black Swans average stacks and causing way more triggers. Kafka also provides a 100% ATK to all allies with at least 75% Effect Hit Rate which is a good DPS boost.
Hysilens is an incredibly powerful DoT Main DPS that synergises perfectly with Black Swan. Hysilens will get a significant damage boost from Black Swans 72% DMG boost and, Hysilens will get a massive quantity of Arcana stacks as Hysilens has multiple DoT Effects on each enemy which will independently cause Arcana to gain stacks. Additionally, her unique mechanic from her ultimate will also add additional Arcana stacks.
Sampo is a DoT based Nihility Sub DPS that applies Wind Shear to all targets with his Ultimate or more slowly from his Skill Bounces. With at least Sampo's E4 his Skill will cause Wind Shear to instantly deal damage per hit of the Skill if there are at least 5 stacks on the enemy. As Arcana is counted as a Wind Shear this will cause Arcana to immediately trigger and deal damage. The total multiplier for this is quite low so Sampo is still worse than Kafka.
Black Swan's Best Teams
Black Swan is an very strong DPS Character but she is significantly weaker as a DPS in teams without Kafka. Teams with both Hysilens and Cyrene are viable but do significantly less damage until Cyrene uses her Ultimate which can take a very long time without E2. Teams that use Sampo over Kafka do approximately half as much DPS.
This is not a comprehensive list of teams. The inclusion or exclusion of any given team does not necessarily reflect its power level. We have included several example teams that are more F2P friendly using 4★ characters that are lower power than the 5★ teams as examples. The Sustain Character in each team can be swapped out.
