Who Counters Summertime Iseria in Epic Seven?

Tori, Empyrean Ilynav, Hecate and other hard counters counter Summertime Iseria. Her bombs and Attack-down can be resisted or blocked outright by immunity, neutering the detonation payload her whole rotation is built around.

Effect resistance and immunity: Her bombs and Attack-down can be resisted or blocked outright by immunity, neutering the detonation payload her whole rotation is built around. Cleanse and buff-removal support: Cleansers wipe the bombs off her targets before they explode, and enemies that strip or steal her team's buffs undo the offensive setup she enables. Shortened buff and debuff timers: Bombs run on a fixed countdown; effects that shorten debuff duration can pop or remove them on the enemy's terms, robbing her of the timed burst. Setup dependence and conditional passive: Her best turn requires bombs already on the field and her passive only triggers once every three turns after an ally hits all enemies, so disrupting that ally or denying the all-target attack stalls her core combo.

Buff-stacking and shield-reliant enemies: Her first skill can dispel two buffs from a target, ripping away the attack, defense, and barrier layers that those teams stack to stay alive, then her Attack-down on the AoE further softens their offense. Teams she races for the opening blow: Her passive grants a 15% Combat Readiness boost to the whole team after an ally's all-target attack, and a guaranteed free first Soulburn, letting her squad jump ahead in the turn order and act before the enemy sets up. Fragile backlines and clustered enemies: Bombs planted by her passive detonate at the end of her third skill for a chunk of fixed damage across the whole enemy team, punishing squishy lineups that can't survive the timed explosion plus the AoE hit. Defensively patient compositions: She pairs Attack-down on all enemies with buff stripping, cutting the damage of stall-and-counter teams while her free Soulburn and crit immunity keep her own pressure rolling.
