Learn how to Cassiopeia counter with these essential tips.

All
Turn away when Cassiopeia casts her R — her ultimate only stuns champions facing her direction; turning away reduces it to just a slow.
Basic Team Fight Skirmish
Back away when poisoned by her Q or W — when poisoned, each of her E casts deals bonus damage and heals her, making her trades much stronger.
Basic Lane Phase Skirmish
Force trades when her Q misses — without her Q's poison, her E deals significantly less damage and doesn't heal her, creating a window of weakness.
Lane Phase Skirmish
Keep spread out in team fights — her ultimate is most effective when it can hit multiple champions in its cone, especially if they're facing her.
Team Fight
Move unpredictably to dodge her Q — her Noxious Blast has a 0.4-second delay before exploding, which gives you a brief window to sidestep it.
Lane Phase
Engage when her W (Miasma) is on cooldown — without her grounding effect, she's much more vulnerable to champions with mobility.
Lane Phase Skirmish
Avoid fighting in narrow jungle corridors — her ultimate and W are particularly effective in confined spaces where you have limited movement options.
Skirmish Team Fight
Cassiopeia is exceptionally strong at level 2 with access to both Q poison and E spam.
Basic Lane Phase
Cassiopeia's ultimate adds significant all-in potential with its stun at level 6, especially when combined with her poison abilities.
