Playing against Cassiopeia
How to counter and exploit weaknesses
1
Turn away when she casts her R: you'll be slowed instead of stunned if you're not facing her.
2
Her DPS depends on landing Q (poison) — if she misses Q, she can't effectively spam E.
3
W prevents dashes: do NOT dash into the zone, go around it.
4
Cassiopeia doesn't have boots — slows are particularly effective against her.
