Hysilens
Yes for DoT—Hysilens is a top Physical Nihility DoT piece. Ultimate “Maelstrom Rhapsody” deploys a team Zone with RES PEN / Break-oriented amp. Best with Kafka / Black Swan. DoT team piece; weak as a solo carry. Skip when you’re not building DoT.
Hysilens is a 5★ Physical Nihility Debuffer. Skill “Overtone Hum: Chorus After Dark Tides” is the primary in-combat spend. Ultimate “Maelstrom Rhapsody” is the payoff window for damage or team utility. This Phase 1 page covers kit text, gear targets, and pull notes—team comps stay empty until Phase 2.

Strengths
- Ultimate “Maelstrom Rhapsody” hits every enemy on the field in one cast—level this before polishing filler traces.
- Skill “Overtone Hum: Chorus After Dark Tides” hits every enemy on the field in one cast—that is how Hysilens applies pressure between Ultimates.
- DEF shred from “Maelstrom Rhapsody” multiplies every ally’s damage for the duration—Hysilens is doing amp work, not only personal DPS.
- Talent “Sirenic Serenade” rolls a base-chance debuff that wants Effect Hit Rate—ignore it and Hysilens plays like a worse generic Nihility unit.
Weaknesses
- Several Hysilens effects roll “base chance”—without enough Effect Hit Rate, Exposed/Shock/DEF shred simply misses on tanky bosses and the rotation feels empty.
- If Energy or Skill Points starve “Maelstrom Rhapsody”, Hysilens spends turns on Basics and the kit’s advertised multipliers never show up on the combat log.
- Spamming “Overtone Hum: Chorus After Dark Tides” every turn without watching Skill Points strands the rest of the team—Hysilens is often the SP sink.
- If “Maelstrom Rhapsody” is still offline at the end of a MoC cycle, the build is usually Energy/ERR or rotation order—not a missing CRIT roll.
Trace Priority
Overtone Hum: Chorus After Dark Tides carries most of the kit’s damage or utility—level this first.
Maelstrom Rhapsody supports the main rotation—raise after the top priority traces.
Sirenic Serenade supports the main rotation—raise after the top priority traces.
Aeolian Mode: Echoes in Still Waters is last priority outside of filling trace materials.
Stat Priority
Open with Technique if it helps, spend Skill to advance the kit’s resource, and hold Ultimate for the damage or buff window. Exact teammate order lands in Phase 2.
Open supports first, then spend the carry’s Skill/Ult inside the buff window. Exact order varies by the team tab above.
Light Cones
5★ · Path cone
Increases the wearer's Effect Hit Rate by 0.4%. When an enemy target gets inflicted with a debuff by the wearer, there is a 0.8% base chance for them to enter "Enthrallment," lasting for 3 turn(s). Effects of the same type cannot stack. While the target is in "Enthrallment," for every 1 debuff applied by the wearer on the target, increases the target's received DoT by #4[f1]%, stacking up to 6 time(s). When the target gets attacked by an ally, increases the attacker's SPD by #6[f1]% for 3 turn(s). When the wearer gets knocked down, removes all "Enthrallment."
Why it works —Signature / best-in-slot when owned—passive lines up with Hysilens’s kit triggers.
5★ · Path cone
Increases the wearer's Effect Hit Rate by 0.24%. When the wearer deals DMG to an enemy that currently has 3 or more debuffs, increases the wearer's CRIT Rate by 0.12%. After the wearer uses their Basic ATK, Skill, or Ultimate, there is a 1% base chance to implant Aether Code on a random hit target that does not yet have it. Targets with Aether Code receive 0.12% increased DMG for 1 turn.
Why it works —Flexible alternative on the same path—equip if you already own it at higher superimposition.
4★ · Path cone
For every debuff the target enemy has, the DMG dealt by the wearer increases by 0.12%, stacking up to 3 time(s). This effect also applies to DoT.
Why it works —Best accessible option for most accounts—raise superimposition when copies drop.
4★ · Path cone
Increase the wearer's CRIT Rate by 0.08%. The wearer deals 0.24% more CRIT DMG to enemies that are currently Slowed or have reduced DEF.
Why it works —Budget path cone—fine while building the account.
Relics
Team Compositions
Hysilens enabling Black Swan. Black Swan, Kafka, Huohuo complete the dot shell.
Black Swan seeds or detonates DoTs — without a second DoT piece the detonation loop stalls.
Enabler / amp piece this page is built around — keep their buffs or debuffs online every cycle.
Kafka seeds or detonates DoTs — without a second DoT piece the detonation loop stalls.
Huohuo covers healing (and often Energy / cleanse) so the carry can stay on-curve.
Traces & Eidolons
Traces
Deals Physical DMG equal to 140% of Hysilens's ATK to one designated enemy.
Has a 100% base chance to increase the DMG taken by all enemies by 25%, lasting for 3 turn(s). At the same time, deals Physical DMG equal to 175% of Hysilens's ATK to all enemies.
Hysilens deploys a Zone that reduces enemy targets' ATK by 15.0% and DEF by 30.0%, and deals Physical DMG equal to 240% of Hysilens's ATK to all enemies. For every 1 instance of DoT taken by an enemy target within the Zone, Hysilens deals Physical DoT equal to 100.0% of her ATK to them. This damage triggers at the start of each turn or after one attack by an ally target, up to 8 time(s). And it cannot repeatedly trigger this effect. The Zone lasts for 3 turn(s) and this duration decreases by 1 at the start of this unit's every turn. When Hysilens gets knocked down, the Zone will also be dispelled.
When an ally target attacks, there is a 100% base chance for Hysilens to inflict the hit enemy target with one of the following states: Wind Shear, Bleed, Burn, or Shock. Priority is given to inflicting a different state. While in the Wind Shear/Burn/Shock state, at the start of each turn, the enemy target takes Wind/Fire/Lightning DoT equal to 31.3% of Hysilens's ATK for 2 turn(s). While in the Bleed state, at the start of each turn, the enemy target takes Physical DoT equal to 20.0% of their Max HP, up to 31.3% of Hysilens's ATK, lasting for 2 turn(s).
After using Technique, creates a Special Dimension that lasts for 20 seconds and automatically moves forward. Enemies within the Special Dimension enter the "Soulstruck" state. "Soulstruck" enemies will not attack ally targets and will follow the dimension while it persists. After entering combat with "Soulstruck" enemies, there is a 100% base chance to inflict each enemy target with 2 of the following states: Wind Shear/Bleed/Burn/Shock, all of which are equivalent to those provided by Hysilens's Talent effect. Only 1 Dimension Effect created by allies can exist at the same time.
Eidolons
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.
