Kennen Ability (LoL): Lightning Rush

Kennen transforms into a ball of electricity, disarming himself but becoming Ghost ghosted and gaining 100% bonus movement speed for 2 seconds, while also gaining 10 / 20 / 30 / 40 / 50 bonus armor and bonus magic resistance while active.

Kennen deals 80 / 120 / 160 / 200 / 240 (+80% of ability power) magic damage to all enemies he passes through, halved against non-champions and restores 40 energy the first time Lightning Rush damages an enemy.

Kennen gains 30 / 40 / 50 / 60 / 70% bonus attack speed for 4 seconds upon exiting Lightning Rush.

Kennen can reactivate Lightning Rush to prematurely cancel it, allowing him to use basic attacks again.
