Who Counters Lionheart Cermia in Epic Seven?

Perfumer Byblis, Frieren, Shepherd of the Dark Diene and other hard counters counter Lionheart Cermia. Her Defense buff and the immunity from her passive are removable; stripping or stealing them leaves her without protection and exposed to debuffs she would normally shrug off.

Heroes that strip or steal buffs: Her Defense buff and the immunity from her passive are removable; stripping or stealing them leaves her without protection and exposed to debuffs she would normally shrug off. Buff-duration shorteners: Cutting the duration of her Defense and immunity buffs ends her shine window early, so debuffs and control can land before she can react again. Enemies that deny her bonus-attack trigger: Her cleanse, immunity, Combat Readiness push, and cooldown reset all hinge on an ally landing an extra attack, counterattack, or dual attack; against a team that gives her no such trigger, the passive never fires and she loses her sustain and recycling. Non-Defense burst that ignores her stats: Her durability and damage both lean on Defense and on the shine buffs; attackers that bypass Defense or burst her down before her passive can refresh leave her without her main lever.

In current Champion+ RTA, Perfumer Byblis has one of the strongest records against Lionheart Cermia (63% win rate over 26,202 games).

Debuff and damage-over-time teams: Her passive cleanses all debuffs on herself and grants immunity for 3 turns whenever an ally takes a bonus attack, so poison, bleed, and other lingering damage effects fall off and stop sticking. Stun, silence, and other crowd control: The same immunity window blocks new control effects from landing, and the cleanse removes ones already on her, letting her keep acting through lockdown attempts. High-Defense walls and tanky front lines: Her ultimate hits everyone while ignoring 50% of the target's Defense and itself scales off her own Defense, so it punches through armored enemies that shrug off normal hitters. Bonus-attack and counter teams she's paired into: Every extra attack, counterattack, or dual attack an ally triggers refreshes her cooldowns and pushes her Combat Readiness by 50%, letting her cycle her defense-piercing ultimate far more often than a normal rotation allows.
