Playing against Sejuani
How to counter and exploit weaknesses
Sejuani needs 4 frost stacks to stun — don't stay in range of her extended autos.
Her Q is a slow and predictable dash — sidestep or Flash the knockup.
She's weak in 1v1 but excels in teamfights — invade her early in the jungle when she's vulnerable.
Tenacity reduces the duration of her many CCs — buy Tenacity if you're frontline.
