Sejuani Ability (LoL): Glacial Prison

Sejuani throws her True Ice bola, stunning and revealing the first enemy champion hit for 1 second and dealing 125 / 150 / 175 (+40% of ability power) magic damage. If the bola travels at least 25% of its range, it stuns and reveals for 1.5 seconds instead. It then also creates an ice storm that slows surrounding enemies by 30% for 2 seconds. All affected enemies take 200 / 300 / 400 (+80% of ability power) magic damage.
