Hysilens is a Physical Nihility DoT damage dealer. Every ally attack lets her inflict Wind Shear, Bleed, Burn or Shock, her Skill makes all enemies take more DMG, and her Zone lowers enemy ATK and DEF while turning each DoT tick into an extra Physical DoT hit. Her Ultimate also detonates every DoT at 150% efficiency, making her the strongest DoT unit alongside Kafka.

Why Does the Ocean Sing BiS
5★
Signature: 40% Effect Hit Rate towards her 120%, up to +30% DoT taken for the whole team and +10% SPD for attacking allies. Dominant in DoT teams.

Reforged Remembrance
5★
Black Swan's signature: she applies all four DoT types, so it's fully stacked quickly for ATK and DEF ignore — if Black Swan isn't using it.

Patience Is All You Need
5★
Kafka's signature: adds another DoT for her Zone, but no Effect Hit Rate, which makes 120% harder to reach.
DMG +24% and +4.8% SPD per attack (up to 3 stacks); hits inflict Erode, a Shock-like Lightning DoT equal to 60% of ATK.
Eyes of the Prey
4★
Best 4★ (S5): DoT DMG and Effect Hit Rate at the same time.
Effect Hit Rate +20% and DoT +24%.
Good Night and Sleep Well
4★
4★ (S5): more DMG than Eyes of the Prey but no Effect Hit Rate, so only if you already reach 120%. The free It's Showtime (S5) is a weaker fallback with the same drawback.

Guide
How to play
How she works
- Talent. Whenever an ally attacks, Hysilens has a 100% base chance to inflict Wind Shear, Bleed, Burn or Shock on each enemy hit (prioritising a state the target doesn't have yet), each lasting 2 turns.
- Skill. Hits all enemies and makes them take 20% more DMG for 3 turns.
- Zone (Ultimate, 110 Energy). Lowers all enemies' ATK by 15% and DEF by 25% for 3 turns. Each time an enemy inside the Zone takes DoT, Hysilens deals an extra Physical DoT hit equal to 80% of her ATK — up to 8 times at the start of each turn or after each ally attack.
- Traces. A2 deploys the Zone for free at the start of combat and recovers 1 Skill Point every time she deploys it. A4 makes her Ultimate detonate all DoTs on the target at 150% of their original DMG. A6 turns every 10% Effect Hit Rate above 60% into +15% DMG, up to +90% at 120%.
Rotation
- Start with her Technique: every enemy begins the fight with 2 DoT states, and the A2 Zone is already up.
- Use her Skill to apply the Vulnerability debuff; your teammates' attacks spread her DoTs.
- Use her Ultimate right before the Zone expires to redeploy it and detonate all DoTs at 150%.
Tips
- 120% Effect Hit Rate is her most important stat: it maxes her A6 and makes her debuffs land.
- She needs frequent hitters to trigger her Zone; Kafka is by far her best partner, followed by Black Swan.
- After a boss changes phase, you'll need to rebuild her DoTs.
Strengths
- Excellent DoT damage, applying all four elemental DoT types
- Consistent Vulnerability, DEF reduction and a big ATK reduction on all enemies
- Stacks DoTs passively through her allies' attacks
- Detonates DoTs at 150% efficiency with her Ultimate
- Skill Point-efficient thanks to her Zone
Weaknesses
- Practically requires Kafka
- Needs ramp-up time, and DoTs must be reapplied after boss phase changes
- Needs a huge amount of Effect Hit Rate
Notable dupes · Eidolon

Big upgrade
Exceptionally strong: all allies' DoT deals 116% of its DMG, and each Talent application adds a second DoT state, so she maxes her Zone's 8 triggers on her own.
E2
Solid upgrade
While the Zone is active, her A6 DMG bonus (up to 90%) applies to all allies.
E6
Solid upgrade
Her Zone can trigger up to 12 times per turn or attack, with a 20% higher multiplier.
