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 Kafka
Hysilens is currently the strongest DoT Main DPS and works perfectly with Kafka. Kafka has a very high frequency of attacks which will apply all of Hysilens' DoT effects very rapidly. Additionally, Hysilens' main source of damage comes from her Ultimate trigger on every DoT tick. This damage does not get reduced by reduced Tick modifiers on abilities (Such as the 80% effect on Kafka's A6 Trace), dealing full damage.
Black Swan is a very strong DoT based DPS whom just received a Novaflare buff dramatically increasing her overall DPS. Kafka can trigger DoTs multiple times per turn which will stack up an extremely large number of Arcana Stacks before they get reset allowing Black Swan to deal massive damage.
Robin is a very versatile Harmony support that gives large ATK and DMG% buffs to the entire team. Robin receives additional energy for her Ultimate when allies use Follow-up ATKs and Kafka has one of the highest number of Follow-up ATKs per turn of any characters in the game, helping to charge Robin's ultimate quickly. Robin's Ultimate will also Action Advance the entire team giving you a lot more turns over an entire fight!
Aventurine is a skill point positive Preservation Sustain Character. Aventurine synergises with characters that use Follow-up ATKs gaining stacks towards triggering free shields each time one is launched.
Kafka's Best Teams
Kafka is an incredibly strong support for the DoT main DPS characters. If you do not have either Hysilens or Black Swan then Kafka is significantly weaker and may struggle to clear content when played with other DoT units.
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.
