Hysilens Kit Overview: Abilities and Core Mechanics
Hysilens operates as a Physical Nihility DoT specialist with zone-based mechanics amplifying team damage.
Basic Attack: Aeolian Mode - Echoes in Still Waters
Deals 50-110% ATK Physical DMG across 2 hits. Dual-hit nature triggers Light Cone passives frequently. Scales to max efficiency at level 10. Serves as Skill Point-positive action for energy management.
Skill: Overtone Hum - Chorus After Dark Tides
Delivers 70-154% ATK Physical AoE DMG, applies 10-22% DMG vulnerability debuff for 3 turns. Stacks multiplicatively with other damage amplification. At max level, 22% vulnerability provides substantial team DPS increases.

Ultimate: Maelstrom Rhapsody
Deals 120-216% ATK Physical AoE damage, deploys 3-turn zone. Zone effects: 15-27% ATK reduction, 20% All-Type RES reduction (E4), triggers Physical DoT 32-88% ATK up to 8 times (12 at E6). Trace A4 passive detonates all active DoTs at 150% original damage when Ultimate activates. Zone persists after Hysilens leaves field.
Talent: Sirenic Serenade
Inflicts four DoT types:
- Wind Shear: 10-27.5% ATK over 2 turns, stacks 5x
- Bleed: 20% Max HP capped at 10-27.5% ATK over 2 turns
- Burn & Shock: Applied through attacks
Multi-DoT application maximizes Prisoner in Deep Confinement value (ignores 6% DEF per DoT, up to 18%).
Technique: At Ocean's Abode
Creates 20-second dimension applying Soulstruck state. Trace A2 The Gladius of Conquest deploys zone for 3 turns and recovers 1 Skill Point when using Technique.
Understanding Hysilens Stat Scaling
Damage scales across three vectors: ATK for DoT base damage, Effect Hit Rate for application, Speed for action frequency.
Primary Stat Priority
- Effect Hit Rate: 120% minimum to land DoTs against endgame enemies
- ATK: 3600 target for direct damage and DoT scaling
- Speed: 135+ for turn frequency, must be 1 higher than Kafka in dual-DoT teams
Secondary Stats
- Physical DMG% on Planar Sphere: multiplicative scaling
- Energy Regeneration Rate on Link Rope: competes with ATK%, depends on Light Cone
- Trace A6 The Fiddle of Pearls: +15% DMG per 10% EHR over 60%, maxes at 90% bonus at 180% EHR
Light Cone Stat Impact
Signature Why Does the Ocean Sing provides 40-60% EHR, solving half the requirement and freeing substats for ATK/Speed. Alternatives like Reforged Remembrance offer 40% EHR plus ATK scaling, while Eyes of the Prey provides 40% EHR and 48% DoT damage at S5.
Energy Requirements
Optimal rotation achieves Ultimate every 3 turns without external support. With proper Skill Point management and sustain character energy generation, ERR rope becomes optional, allowing full ATK% investment.
Trace Leveling Priority
Ultimate > Talent > Skill > Basic Attack
Ultimate: Absolute priority due to 150% DoT detonation multiplier from Trace A4. Each level increases direct damage and zone's Physical DoT triggers.
Talent: Governs all DoT application percentages, directly scales sustained damage.
Skill: Third priority, debuff scales from 10% to 22%.
Basic Attack: Minimal investment until others maxed.
Early Game (Level 1-40)
- Ultimate levels 1-6
- Talent levels 1-4
- Unlock Trace A2 for Skill Point recovery
- Skip Basic Attack entirely
Mid Game (Level 40-60)
- Ultimate to level 8
- Talent to level 7
- Skill to level 6
- Unlock Trace A4 (150% DoT detonation)
Endgame (Level 60-80)
- Ultimate to level 10
- Talent to level 10
- Skill to level 10
- Unlock Trace A6 (EHR-scaling damage)
- Basic Attack only if materials abundant
Minor traces: ATK +18%, SPD +14, EHR +10%.
Materials
Full Ascension requires: 15 Fear-Stomped Flesh, 15 Courage-Torn Chest, 15 Glory-Aspersed Torso, 65 Invasive Clot, 308,000 Credits. Total investment: 3-4 weeks dedicated farming without Stellar Jade refreshes.

Signature Deep Dive: Worth Pulling?
Passive Synergy
60% EHR at S1 solves stat requirement. DoT vulnerability stacks (up to 60% at 6 debuffs) multiply with Skill's damage vulnerability. Speed buff (20% for 3 turns) activates consistently, creating self-sustaining cycle.
Damage Comparison
Controlled testing (Hysilens, Kafka, Black Swan, Huohuo):
- Signature S1: 100% baseline
- Reforged Remembrance S1: 85-88%
- Eyes of the Prey S5: 78-82%
- Good Night S5: 65-70%
Gap translates to 0.5-1 cycle difference in Memory of Chaos.

Best 4-Star Light Cones (F2P)
Eyes of the Prey: Top F2P
- Stats: 40% EHR, 48% DoT damage at S5
- Acquisition: Battle Pass/event shops
- Build adjustment: Need 80% EHR from relics (6-7 substat rolls)
Unconditional passive, ideal for learning rotations.
Good Night and Sleep Well: Situational
Excels in Pure Fiction (frequent enemy defeats). Boss content sees significant drops. Requires 120% EHR from relics alone (9-10 substat rolls), limiting ATK/Speed optimization.
Performance Gap Quantified
S5 Eyes of the Prey vs S1 signature: 18-22% damage gap. Translates to 1-2 additional Memory of Chaos cycles or 3,000-5,000 fewer Pure Fiction points. Gaps remain clearable with skill and optimization.
Superimposition Priority
Eyes of the Prey: Gains 8% DoT damage per level. S5 = 40% improvement over S1. Use duplicates immediately.
Good Night: Gains 4% per level. Lower scaling but worthwhile.
Light Cone Comparison: Tested Numbers
Testing Methodology
Identical builds: Prisoner 4pc, ATK% Body, Speed Feet, Physical DMG% Sphere, ATK% Rope. Substats: 3600 ATK, 120% EHR (adjusted for Light Cone), 135 Speed. Team: Hysilens, Kafka, Black Swan, Huohuo. Memory of Chaos Floor 12, 10 runs per Light Cone.
Single-Target Damage (5-cycle avg)
- Why Does the Ocean Sing S1: 487,000
- Reforged Remembrance S1: 425,000
- Eyes of the Prey S5: 392,000
- Good Night S5: 341,000
Signature's lead compounds over longer fights via Speed buff.
AoE Performance (Pure Fiction avg score)
- Why Does the Ocean Sing S1: 34,200
- Reforged Remembrance S1: 31,800
- Eyes of the Prey S5: 29,400
- Good Night S5: 28,100
Gap narrows in AoE due to Good Night's frequent passive triggers.
Skill Point Economy
Signature's Speed buff generates 0.3-0.5 additional actions per cycle = 1-2 extra Skill uses over 8-cycle encounters. Enables aggressive Skill usage without depleting resources. 4-star options require conservative Skill usage.
Skill Rotation and Light Cone Synergy
Optimal 3-Turn Rotation
- Turn 1: Skill → damage vulnerability + initial DoTs
- Turn 2: Skill/Basic Attack → maintain stacks + energy
- Turn 3: Ultimate → detonate all DoTs at 150%
Kafka acts immediately after Ultimate for double-detonation burst.
Light Cone Impact on Timing
Signature: Speed buff enables 2.5-turn rotations in optimal conditions. Requires precise Speed tuning.
Reforged Remembrance: Prophet stacks build over 4 actions. Extend first rotation to 4 turns for max stacks, then 3-turn cycles.
4-star: Follow standard 3-turn pattern consistently.
Energy Management
Without external support: 2 Skill uses + 1 Basic Attack across 3 turns. With Huohuo: 3 consecutive Skills for max damage vulnerability uptime. Technique's Skill Point recovery enables aggressive first rotation.
Common Mistakes
- Using Ultimate before 3-4 DoT types active
- Allowing DoTs to expire before Ultimate
- Poor Kafka sequencing (must act immediately after Ultimate)
- Overusing Basic Attack with signature (Speed buff enables more Skills)
Eidolon Impact on Light Cone Selection
E0 vs E1 vs E2
E0: Demands max Light Cone investment. Signature nearly essential for endgame.
E1: Grants allies 116% original DoT damage + 100% chance for additional DoT instances. Doubles application frequency, increasing DoT damage% value. Eyes of the Prey gap narrows to 15-18%.
E2: Applies The Fiddle of Pearls party-wide within zone (EHR-scaling damage bonus for all allies). Shifts value toward team composition. Makes 4-star options more viable.
Does E2 Need Signature?
E2 + S5 Eyes of the Prey performs within 10-12% of E2 + signature (vs 18-22% gap at E0). Party-wide buff compensates for individual Light Cone deficits. Players with E2 can skip signature, invest in team improvements (Black Swan signature, Kafka Eidolons).
Budget Strategy
F2P optimal path: E0 + signature over E2 + 4-star. Former provides more consistent performance across content. Players with 4-star Light Cones should save for future characters rather than chase Eidolons.
Game Mode Specific Recommendations
Memory of Chaos
Prioritizes sustained single/dual-target damage over 8-12 cycles. Signature provides max value (0.5-1 cycle improvement). Reforged Remembrance best alternative (DEF ignore valuable vs high-DEF elites). 4-star options require 1-2 additional cycles and perfect execution.
Pure Fiction
Multi-wave structure favors burst damage. Signature maintains top performance via Speed-enabled additional Ultimates. Good Night shows improved relative performance (frequent enemy defeats). Gap narrows to 20-25% vs 30-35% in single-target. Eyes of the Prey remains balanced choice.
Apocalyptic Shadow
Extended encounters favor consistent DoT application. Signature provides reliable performance across boss types. Reforged Remembrance excels (extended fights allow full Prophet stacks, DEF ignore scales with difficulty).
Scores: Signature 3,257, Reforged 2,980, Eyes 2,740 (8-15% spread).
Common Misconceptions Debunked
Myth: Needs Maximum Energy Regeneration
Reality: Standard generation provides sufficient Ultimate uptime in 3-turn rotations. ERR rope sacrifices 43.2% ATK for marginal flexibility. Testing shows ERR enables 2.5-turn rotations but ATK loss reduces Ultimate damage 12-15%, negating frequency advantage. ATK% rope delivers superior total damage.
Myth: Signature Mandatory for Viability
Reality: Signature provides 18-28% advantage, but S5 Eyes of the Prey enables all content clears with proper team/relics. Gap translates to 1-2 additional cycles, not impossible content. 45.61% of players use non-signature while maintaining competitive clear rates. Signature accelerates progression but doesn't gatekeep content.
Myth: Basic Attack Can Be Ignored
Reality: Serves essential Skill Point economy, contributes 15-20% total damage in sustained rotations. Dual-hit triggers support abilities and Light Cone passives twice per action. Level to 6-8 endgame after other traces maxed.
Future-Proofing Investment
Viability Projection
Released Version 3.5 (July-August 2025). DoT archetype continues receiving support, suggesting sustained viability through Version 4.0+. Physical typing provides niche value, multi-DoT application enables universal synergy with Kafka/Black Swan. Dual-purpose design suggests longer meta relevance.
Light Cone Longevity
Why Does the Ocean Sing's EHR and DoT vulnerability remain valuable for future Nihility DoT characters. Investment extends beyond Hysilens. 4-star options offer zero opportunity cost (no Stellar Jade consumed).
When to Stop Investing
Players achieving 3-star Memory of Chaos and 36,000+ Pure Fiction should redirect resources to team expansion. Investment ceiling: E0 + signature S1, 3600+ ATK, 120% EHR, 135+ Speed. Further optimization yields diminishing returns vs building complementary characters.
FAQ
What is Hysilens kit and how do her abilities work?
5-star Physical Nihility DoT specialist. Basic Attack: dual-hit Physical damage. Skill: AoE damage + 10-22% damage vulnerability. Ultimate: 3-turn zone reducing enemy ATK 15-27%, triggering Physical DoT up to 8 times. Talent: inflicts Wind Shear, Bleed, Burn, Shock DoTs. Trace A4 detonates all active DoTs at 150% when using Ultimate.
Which Light Cone is best for Hysilens in 2026?
Why Does the Ocean Sing: 40-60% EHR, DoT vulnerability up to 60% at 6 debuffs, 10-20% Speed buffs. 23-28% damage advantage over alternatives. F2P: Eyes of the Prey S5 (40% EHR, 48% DoT damage), performs 18-22% below signature but viable for all content.
Is signature Light Cone worth pulling?
Worth pulling for top-tier performance or if lacking strong Nihility Light Cones. Provides 18-28% damage increase, solves EHR requirements. Skip if you have Reforged Remembrance or S5 Eyes of the Prey—gap doesn't prevent clears.
What are best F2P Light Cones?
Eyes of the Prey S5: 40% EHR, 48% unconditional DoT damage. Good Night and Sleep Well: 24% DoT damage on enemy defeat (good Pure Fiction, struggles bosses). Eyes maintains 78-82% of signature performance across modes.
What trace level first?
Ultimate > Talent > Skill > Basic Attack. Ultimate's 150% DoT detonation (Trace A4) = largest damage spike. Unlock Trace A2 early (Skill Point recovery), Trace A6 for EHR-scaling damage. Early: Ultimate 6, Talent 4. Mid: Ultimate 8, Talent 7. Endgame: Ultimate 10, Talent 10, then Skill 10.
How to optimize rotation?
3-turn: Turn 1 Skill (vulnerability + DoTs), Turn 2 Skill/Basic (energy), Turn 3 Ultimate (detonate at 150%). Kafka acts immediately after Ultimate for double-detonation. Signature's Speed buff enables 2.5-turn rotations. Avoid Ultimate before 3-4 DoT types active. Ensure DoTs active during detonation.
