While Hysilens is on the field, the DoT dealt by ally targets is equal to 116% of their original value. When Hysilens inflicts Wind Shear/Bleed/Burn/Shock on enemies via her Talent, there is a 100% base chance to additionally inflict the target with 1 instance of Wind Shear/Bleed/Burn/Shock state that is equivalent to those from the original Talent effect and can coexist with such pre-existing states.
While the Zone is active, the DMG Boost effect from Trace "The Fiddle of Pearls" applies to all allies.
While the Zone is active, reduces All-Type RES of all enemies by 20%.
While the Zone is active, at the start of each turn or after one attack by an ally target, increases the maximum trigger count for Hysilens's Physical DoT effect to 12, and increases the multiplier of the DMG dealt by 20%.
Kafka detonates the stacks Black Swan and a third Nihility unit apply, so every slot but the sustain exists to keep a damage-over-time state on the enemy.
He taunts, spends his own HP for a Zone that shreds DEF, and scales on Max HP: a carry that needs a healer more than it needs a second buffer.
Honkai: Star Rail 5★ Physical Nihility Sub DPS
Why Does the Ocean Sing tops the light cone ranking for Hysilens, at 125.77% relative damage at S1, ahead of Reforged Remembrance, Those Many Springs and Patience Is All You Need. That order is prydwen.gg's, measured in play and rephrased here; every row of it sits under Light cones below.
Run Prisoner in Deep Confinement on Hysilens, with Champion of Streetwise Boxing and Pioneer Diver of Dead Waters behind it. The planar ornament is Revelry by the Sea. Main stats are Effect HIT Rate = ATK% body, ATK% >= Speed feet, Physical DMG = ATK% sphere, ATK% > Energy Regen Rate rope. Roll substats in the order Effect Hit Rate to 120% = SPD (Until Desired Breakpoint) > ATK%.
Trace priority is Ultimate > Talent = Skill > Basic. The Ultimate costs 110 energy, which is what an Energy Regeneration Rate target has to clear.
Hysilens plays DoT applier in the Kafka team, alongside Kafka, Black Swan and Huohuo.
