A personal guard of Emperor Pascal who had been by his side ever since the emperor rose to the throne. He was a loyal subject who did not hesitate to offer sincere advice for the future of the empire. However, because of this, Bai Jiao schemed to remove him and framed him for treason, leading to the execution of him and his family. He now wanders around the imperial palace seeking revenge on Bai Jiao, who took everything from him.

Verdict

Strength

Frostbite Immunity to allies

Weakness

Extremely low stats, no meaningful combat utility

Kang Jae is an Extra-tier hero in Seven Knights Idle Adventure and is not intended for combat use at any stage of the game. Like all Extra-tier heroes, his primary purpose is to be leveled up for the Codex rewards, which grant Rubies and permanent stat bonuses for your account.

His Frostbite Immunity provides negligible utility compared to modern Legendary heroes and is completely outclassed in any serious content.

Strengths

Codex Completion — The primary purpose for this hero is to be leveled for Codex rewards.

Weaknesses

No combat viability — Cannot compete with Legendary or Awakened heroes.

Extremely low damage — Damage output is far below modern standards.

Negligible utility — Frostbite Immunity alone provides no meaningful team benefit.

When to Use

Codex progression only — Only purpose is to level up for Codex rewards.

When to Avoid

Any team composition

Any combat scenario

Better Alternatives

Surtr the Last Giant Top-tier Melee delivering massive damage with HP scaling — far exceeds any utility from weak status immunity.

Devourer of the End Times Fenrir Top-tier Melee with +24% Vital Strike and AOE damage — provides superior boss-killing power compared to Frostbite Immunity.

Troublemakers Branze & Bransel Elite Melee with +45% Attack and team utility — replaces narrow status immunity with comprehensive support.
