Who Counters Blood Blade Karin in Epic Seven?

Perfumer Byblis, Lady of the Scales, Frieren and other hard counters counter Blood Blade Karin. Her sustain leans entirely on lifesteal from her basic attack, so an enemy that blocks healing cuts off her recovery and lets her be ground down.

Anti-heal effects: Her sustain leans entirely on lifesteal from her basic attack, so an enemy that blocks healing cuts off her recovery and lets her be ground down. Buff strip and theft: Dispel, buff stealing, and effects that shorten buff duration peel off her start-of-battle immortality and her self Attack buff, removing the safety net and the damage spike she counts on. Cooldown windows: Her only area hit is locked behind a 5-turn cooldown, so between casts she is limited to single-target attacks and a fast enemy can punish the gap before it comes back up. Health-pressure punishers: She willingly spends 20% of her current Health to use her area attack and her scaling rewards being low, so a strong burst or a damage-over-time enemy can finish her before her immortality or speed advantage matters.

In current Champion+ RTA, Frieren has one of the strongest records against Blood Blade Karin (61% win rate over 2,853 games).

Counterattack teams: Her area attack explicitly cannot trigger an enemy counterattack, so units that rely on punishing her with retaliation strikes get hit for free and never fire back. Low-health damage races: As her Health falls she gains Attack, Defense, and Speed, and one turn of immortality at battle start lets her survive a burst that would kill a normal assassin, so she comes out of an opening exchange faster and hitting harder. Squishy backline finishers: Her single-target draw heals her on hit and refunds 15% Combat Readiness, climbing to 50% when she lands a kill, letting her chain extra turns and pick off low-defense targets one after another. Clustered low-Health enemies: Blade Art: Dragon strikes the whole enemy team at once, and any kill it scores pushes her another 50% toward her next turn, so it cleans up a group that is already softened.
