Who Counters Victorika in Epic Seven?

Frieren, Rinak, Notos and other hard counters counter Victorika. The Decreased Defense she relies on to amplify her team's damage gets wiped the moment an opposing healer scrubs debuffs off, undoing her setup.

Enemy cleansers: The Decreased Defense she relies on to amplify her team's damage gets wiped the moment an opposing healer scrubs debuffs off, undoing her setup. Buff strippers: The team-wide immunity she grants from her ultimate can be torn off by an enemy that removes buffs, leaving her allies exposed right after she spent her long cooldown protecting them. Enemies who already run their own immunity: Her Defense-down has a chance to land at best and is fully blocked by a target that is immune, so her core damage setup can whiff against protected foes. Fast burst before she acts: She is slow and has no passive, so her protective immunity only goes up when it is her turn; a quicker opponent can land hard crowd control or open the kill before she ever gets to cast, and both her area attack and ultimate then sit on four-turn cooldowns.

Beefy tanks and high-HP bruisers: Her ultimate deals more damage the larger the target's max Health, so the chunkier the wall in front of her, the harder she hits it; her first skill can also peel away part of that Defense to make follow-up damage land for the whole team. Teams that lean on debuffs and crowd control: Her ultimate blankets all allies in immunity for two turns, so an enemy turn meant to land stuns, silences, slows, or a stack of damage-over-time and other debuffs simply bounces off the protected team. Squishy backlines that cluster together: Her four-turn area attack hits every enemy at once, letting her chip down a whole formation instead of trading blows with only one target.
