Damaging an enemy with an ability or basic attack grants 10 / 15 / 20 / 25 (based on level) bonus armor and reduces movement-slowing effects on Sejuani by 10 / 15 / 20 / 25 (based on level)% for 2 seconds. Subsequent damage will increase the duration by 2 seconds up to a cap of 8 seconds, with further damage refreshing the duration.
Active: Sejuani charges forward, knocking enemies into the air and dealing magic damage equal to a flat amount plus a percentage of their 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 each second to enemies within range for 4 seconds. If this ability is reactivated, Sejuani immediately starts swinging her flail.
Passive: Sejuani's abilities and basic attacks apply Frost to enemies for 4 seconds.
Active: All nearby enemies with Frost take magic damage and are slowed, and the Frost debuff is removed from the targets of Permafrost. This spell is unable to be cast if no enemies in range have the Frost debuff.
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.
