Playing against Sejuani

How to counter and exploit weaknesses

1

Sejuani needs 4 frost stacks to stun — don't stay in range of her extended autos.

2

Her Q is a slow and predictable dash — sidestep or Flash the knockup.

3

She's weak in 1v1 but excels in teamfights — invade her early in the jungle when she's vulnerable.

4

Tenacity reduces the duration of her many CCs — buy Tenacity if you're frontline.
