Who Counters Specter Tenebria in Epic Seven?

Frieren, Rinak, Tori and other hard counters counter Specter Tenebria. Her pressure leans on poison ticking for 2 turns and a 1-turn stun; an ally cleanse wipes both, erasing her damage-over-time and freeing the stunned unit before she can capitalize.

Cleanse and debuff-clearing healers: Her pressure leans on poison ticking for 2 turns and a 1-turn stun; an ally cleanse wipes both, erasing her damage-over-time and freeing the stunned unit before she can capitalize. Debuff immunity: Both her poison and her stun are debuffs, so a unit shielded by immunity ignores her control entirely and takes only the raw hit. Early burst before she snowballs: Her ultimate sits on a 5-turn cooldown and her passive needs deaths to stack Attack and Defense; she opens fragile, so a fast team that bursts her down early never lets her ramp up. Dispel that strips her stacks: Her scaling hinges on the self buff from her passive growing her Attack and Defense across the fight; stripping that buff cuts her back to a soft mage with no built-in sustain.

Counterattack teams: Her poison blast explicitly cannot trigger a counterattack, so she chips down counter-reliant defenders and reflect setups without ever feeding their retaliation. Fragile targets she can finish off: Her ultimate stuns one enemy, and if that hit kills it she slashes 50% Combat Readiness off all remaining foes, snapping enemy tempo right as a key unit drops. Slow-burn attrition and stall comps: Her passive stacks bonus Attack and Defense every time anyone dies, up to five times, so drawn-out fights only make her hit harder and tankier, and her poison keeps ticking through defensive turtling. A single priority threat: Her single-target stun for a turn plus lingering poison lets her lock down and slowly grind out one dangerous enemy.
