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.
