Kennen moves very fast and may pass through units, dealing 85/125/165/205/245 (+0.55) magic damage and adding a Mark of the Storm to any enemy he passes through. Additionally, Kennen will gain 10/20/30/40/50 armor and magic resistance for 4 seconds.
Kennen is refunded 40 energy if he passes through an enemy, but can only gain this effect once. Lightning Rush deals half damage to minions.
