Sejuani Ability (LoL): Winter's Wrath

Sejuani swings her flail, dealing 5 / 15 / 25 / 35 / 45 (+20% of ability power) (+4% maximum health) and knocking back minions and jungle monsters. She then lashes out again, dealing 5 / 25 / 45 / 65 / 85 (+60% of ability power) (+8% maximum health) physical damage and briefly slowing targets. Both swings apply stacks of Permafrost.
