Best Relics for Black Swan

Equip Black Swan with top Relics in Honkai: Star Rail. Learn which sets and substats best enhance her Nihility role and damage-per-turn output.

Optimizing Black Swan's Relic set is crucial for maximizing her DoT and debuffing prowess. The premier choice for her is the 4-piece "Pioneer Diver of Dead Waters" set. This set provides a substantial 10% DMG Boost with a 2-piece bonus. The 4-piece bonus is where it truly shines: it increases the wearer's DMG by 4% for each debuff on the target enemy. Furthermore, if the target enemy has 3 or more debuffs, the DMG dealt to them increases by an additional 8%. Given Black Swan's ability to consistently apply Shock and Arcana, this set synergizes perfectly, significantly amplifying her damage output against debuffed foes.

An alternative, though less optimal, option for a 2-piece combination would be to pair the 2-piece "Pioneer Diver of Dead Waters" with a 2-piece "Musketeer of Wild Wheat" or "Eagle of Twilight Relic." The "Musketeer" set provides a 10% ATK boost, which is a primary scaling stat for Black Swan. The "Eagle of Twilight Relic" offers a 10% Wind DMG Boost, further enhancing her damage. However, the 4-piece "Pioneer Diver of Dead Waters" set's conditional DMG increase is generally superior for her specific role.

For Planar Ornaments, the "Space Sealing Station" set is highly recommended. The 2-piece bonus grants an 12% ATK boost. If the wearer reaches 120% or more of the wearer's Base SPD, the ATK boost increases by an additional 12%. This is achievable with Black Swan's base SPD and appropriate Speed boots, making it a powerful choice. Another viable option is the "Firmament Frontline: Glamoth" set, which provides a 5% DMG Boost and, if the wearer's SPD reaches 135 or 150, grants an additional 10% or 18% DMG Boost respectively. This set demands higher SPD investment but can offer a significant DMG increase.

When selecting main stats, prioritize SPD boots to ensure she can take more turns and apply debuffs more frequently. For the Body piece, ATK% is generally preferred, though Effect Hit Rate% might be considered if you are struggling to reach the necessary Effect Hit Rate for her debuffs (typically around 65-70% for reliable application against enemies with average RES). For the Planar Sphere, ATK% is the standard choice. For the Link Rope, ATK% is also the preferred stat. Substats should focus on SPD, ATK%, Effect Hit Rate%, and Crit Rate/DMG if you are building her with some crit investment, though ATK and SPD are generally more impactful for her DoT-focused kit.
