Cassiopeia is a high-value ranged champion with strong early-to-late game scaling, capable of winning melee trades and dominating lanes.
Olaf is a key counter; for other matchups, dodging her Q (Noxious Blast) is crucial. Cassiopeia players often overextend and self-destruct.
Her high skill ceiling allows proficient players to overcome most matchups, so adapt your champion choice and playstyle carefully against her.
