Strength

4000% active skill + reliable Burn application

Weakness

No meaningful team utility, Tier D placement

Cha Hae-in is a Legendary hero from the Solo Leveling collaboration, primarily functioning as a Burn enabler. Her toolkit centers on applying Burn damage over time while delivering focused burst damage with her active skill.

However, her overall performance is limited, as she lacks significant team utility and does not benefit from any DoT scaling mechanics. Her contribution remains minimal in modern team compositions.

Tier D reflects her underwhelming performance. She is a collection filler hero that most players can safely ignore in favor of stronger alternatives in every content type.

Should You Use Cha Hae-in?

No — Cha Hae-in is a Tier D hero with no meaningful team utility and no DoT self-scaling. She is outclassed by Burn DPS heroes like Miraculous Fortune Teller Erin and Vows of Creation Agni. Invest resources elsewhere.

Strengths

Burn application — Applies a Burn effect consistently through her active skills, contributing damage over time.
Burst damage — Delivers focused single-target burst damage through her active skill.
Self-buff — Improves her damage capabilities for a short duration.

Weaknesses

Negligible team utility — Keen Attack grants only +20% Crit Rate for 2 seconds, and Evasion Decrease reduces by only 50%, both well below meaningful thresholds.
No DoT self-scaling — Cha Hae-in applies Burn but does not benefit from it. Her own DoT does not amplify her damage output.
No survivability tools — lacks immortality, shield, or self-healing, making her fragile in harder PvE content and PvP.
Collaboration Hero — Can only be obtained during limited periods.

Best Game Modes

  • Collection — her only real relevance is unlocking rewards by obtaining it. She has no standout performance in any specific game mode.

Build & Optimization

Critical Hit Rate is the recommended potential build for Cha Hae-in. Maximizing Crit Rate ensures her critical hits land frequently, keeping her Burn application and active damage flowing consistently. Critical Hit Damage is the secondary priority.

FAQ

Can Cha Hae-in survive in Hard Boss Challenge without defensive tools?

No. Cha Hae-in lacks any form of self-preservation—she has no immortality buffs, no shields, and no passive self-healing. While she is a ranged unit, distance alone is not enough to protect her from the aggressive area-of-effect (AoE) damage spikes and targeted strikes found in the Hard Boss Challenge. Without heavy external support, she will die quickly.

Is Cha Hae-in worth building if I already have Vows of Creation Agni for Burn?

No, she is a strict downgrade. If you already have Vows of Creation Agni, there is zero reason to invest resources into Cha Hae-in. Agni provides far superior Burn application, significantly higher personal damage, and much better team synergy.
