Who Counters Death Dealer Ray in Epic Seven?

Perfumer Byblis, Genesis Ras, Disciplinary Prefect Aria and other hard counters counter Death Dealer Ray. Her whole kit runs on landing sleep and poison; an enemy immunity buff or high Resistance simply blocks the debuffs, leaving her with weak single-target damage and no control.

Effect Resistance and immunity: Her whole kit runs on landing sleep and poison; an enemy immunity buff or high Resistance simply blocks the debuffs, leaving her with weak single-target damage and no control. Allies who cleanse the team: Her sleep and poison are her payoff, and a healer or support that cleanses debuffs off all allies wipes them away a turn after she lands them, neutralizing her disruption. Buff theft and buff-duration cutting: Stealing the Effectiveness she hands her team undercuts her setup; her Pestilence grant is undispellable so it can not be stolen, but the poison and sleep she applies can still be cleansed off the targets to blunt her control. Faster, burstier enemies: She is slow and depends on her cloud's long cooldown, so quicker openers can move first and her sleep only locks one target at a time, letting the rest of the enemy team burst her down before she rotates again.

In current Champion+ RTA, Perfumer Byblis has one of the strongest records against Death Dealer Ray (65% win rate over 10,582 games).

Teams leaning on stacked buffs: Her poison cloud strips two buffs from every enemy at once, peeling away the attack and defensive buffs that buff-heavy compositions depend on before they can cash them in. Survival-buff defenses that refuse to die: By dispelling buffs across the whole enemy line, she can tear off barriers and the invincibility or cannot-die effects tanks use to outlast a fight, opening them up to be killed. Squishy threats she can lock down early: As a fight-opener she can sleep a key enemy for a turn and follow with poison, taking a dangerous unit out of the rotation while her bonus damage punishes anything already wounded. Slow grind matchups where damage-over-time wins: Her poison ticks for 2 turns and the Pestilence she grants spreads it across the team, chipping down high-health or stalling enemies that try to drag the fight out.
