Enemies hit by Kennen'sabilities receive a Mark of the Storm for 6.25 seconds, stacking up to three times. At three stacks, the marks consume themselves to stun the target for 1.25 seconds and restore 25 energy.
If the stun is applied more than once within 7 seconds, it has a diminished effect and only stuns for approximately 0.5 seconds.
Mark of the Storm is a debuff that automatically applies to any enemy Kennen damages with an ability.
Spell shields do not interact with the passive portion of the ability.
Basic attacks against structures do not stack the counter nor consume the enhanced autoattack.
Electrical Surge's active will still hit stealthed champions and champions hidden in the Fog of War; in such cases, the surging bolts will reveal their position (although it does not grant sight of them).
COST: 100 / 95 / 90 / 85 / 80 energy
COOLDOWN: 10 / 9 / 8 / 7 / 6
Active:Kennen transforms into a ball of electricity, losing the ability to use basic attacks but ignoring unit collision and doubling his movement speed for 2 seconds, while also gaining bonus armor and magic resistance for 4 seconds.
Bonus Resistances: 10 / 20 / 30 / 40 / 50
Kennen deals magic damage to all enemies he passes through, doubled against champions, and restores 40 energy the first time he damages an enemy with Lightning Rush.
Lightning Rush will only damage any particular enemy once per cast.
The full movement speed boost of Lightning Rush brings Kennen over the first soft movement speed cap. Assuming Kennen is not being affected by any other movement speed modifiers, Lightning Rush is effectively a 230 movement speed boost.
The movement speed bonus and damage is separate from the bonus resistances. Cancelling the ability early will not remove the bonus defenses.
Active:Kennen summons a magical storm around himself for the next few seconds, dealing magic damage to a random nearby enemy champion within range every 0.25 seconds.
Duration: 3 / 4 / 5
「 Magic Damage Per Bolt: 80 / 145 / 210 (+ 40% AP) 」「 Total Single Target Damage: 240 / 435 / 630 (+ 120% AP) 」
