Honkai: Star Rail – Hysilens build and ascension guide

Play your enemies a melody to die for with the best Honkai: Star Rail Hysilens build. This follower of The Nihility deals Physical DMG and specializes in inflicting DoT effects.

Hysilens’ Skill, Overtone Hum: Chorus After Dark Tides, deals Physical DMG based on her ATK to all enemies and has a chance of inflicting a debuff on them, which increases all their incoming DMG for three turns.

Her Ultimate, Maelstrom Rhapsody, deals Physical DMG based on Hysilens’ ATK to all enemies and deploys a Zone for three turns that reduces their ATK and DEF. Whenever an enemy in the Zone takes an instance of DoT, Hysilens deals Physical DoT based on her ATK to that enemy. She can do this up to eight times at the start of each turn or after an attack executed by an ally.

One of her Traces also allows her to recover a Skill Point for the team when deploying a Zone, while another causes all active DoTs on her Ultimate’s targets to immediately deal damage.

Hysilens’ Talent, Sirenic Serenade, gives her a chance to inflict a random DoT effect on a target attacked by an ally. She gives priority to inflicting a DoT effect that isn’t present on the target yet. When enemies suffer from Burn, Shock, or Wind Shear at the start of their turn, they take extra DoT based on Hysilens’ ATK for two turns. When enemies suffer from Bleed at the start of their turn, they take extra Physical DoT based on their own Max HP and Hysilens’ ATK.

Obtaining duplicates of Hysilens allows you to increase her Eidolon Level, unlocking additional capabilities:

Honkai: Star Rail – Hysilens: best Light Cones

Hysilens mainly desires ATK and Effect Hit Rate. Her signature Light Cone, Why Does the Ocean Sing, delivers a generous portion of the latter in addition to granting the wearer the chance to inflict the Enthrallment debuff on targets. Enemies suffering from this effect take additional DoT for every debuff applied to them by the wearer, stacking up to six times. The debuffed targets also temporarily grant extra SPD to allies attacking them.

Honkai: Star Rail – Hysilens: best Relics

Effect Hit Rate is a priority for two reasons: Hysilens requires it to increase the chance of her debuffs actually hitting and one of her Traces converts every 10% Effect Hit Rate above 60% into a 15% DMG boost, stacking up to 90% — so your minimum target Effect Hit Rate is 120%. ATK and SPD are your other two big concerns to bolster her damage output.

Energy is not a major issue for Hysilens, since her Zone sticks around for three turns — that’s plenty of time to regenerate enough Energy for the next one. Defensive stats such as HP, DEF, and Effect RES are great fillers, as they’ll enhance Hysilens’ sustainability on the battlefield.

• Prisoner in Deep Confinement (4) – +12% ATK, wearer’s attacks will ignore 6% of enemy’s DEF for every DoT the target is suffering from, counting up to three DoTs.

Honkai: Star Rail – Hysilens: best teams

Hysilens is set to become a pillar of the DoT playstyle thanks to her own substantial DoT infliction and the damage boosts she provides to her allies.

• Kafka (Main DPS), Hysilens (Sub DPS), Black Swan (Sub DPS), Huohuo (Support)

Kafka’s buffs in HSR 3.4 have made her an even stronger DoT DPS, so she’s perfect to take up the Main DPS role in DoT compositions, inflicting damaging effects on her turn as well as out of it thanks to her Follow-Up Attacks. Black Swan remains an incredibly potent DoT Sub DPS, who only grows stronger with someone like Hysilens on the team. Huohuo is an excellent Support for this group, as her ATK buff and Energy Regeneration capabilities provide super useful benefits.

If you don’t want to play a triple DoT line-up, slot in Ruan Mei for Black Swan for that elongated Weakness Break.
