Playing against Sion

How to counter and exploit weaknesses

1

His Q charge can be interrupted by CC — stun him during the channel to cancel the knockup.

2

Sidestep his R (charge): he can't turn easily once he's started.

3

His zombie passive is slow: simply walk away from him, don't stay in range.

4

The W shield can be popped before it detonates: burst it quickly to prevent the damage from going off.
