Damaging an enemy with an ability or basic attack grants 10 / 15 / 20 / 25 bonus armor and reduces movement-slowing effects on Sejuani by 10 / 15 / 20 / 25% for 2 seconds. Subsequent damage will increase the duration by 2 seconds up to a cap of ~8 seconds, where after damage will refresh the duration.
Arctic Assault
Range: 650
Cooldown: 15 / 14 / 13 / 12 / 11
Cost: 80 / 85 / 90 / 95 / 100 mana
Active: Sejuani charges forward, knocking enemies into the air and dealing magic damage equal to a flat amount plus a percentage of the target's maximum health (max 300 damage to monsters). This charge stops after knocking an enemy champion into the air.
Active: Sejuani's next basic attack deals bonus magic damage to the target and enemies near it. She then swings her flail, dealing magic damage to nearby enemies over 4 seconds. If this ability is reactivated, Sejuani immediately starts swinging her flail.
Active: Sejuani throws her frost-forged bola in a line. If the bola hits an enemy champion, it shatters, stunning the target and nearby enemies for a duration. If the bola reaches its maximum range, it shatters and slows enemies by 90% instead for the same duration.
All enemies in the shatter area take magic damage.
