Enemies hit by Kennen'sabilities receive a Mark of the Storm for 6 seconds, stacking up to 3 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 6 seconds, it has a diminished effect and only stuns for ~0.5 seconds.
Basic attacks against structures do not stack the counter nor do they consume the enhanced attack.
Electrical Surge's active will still hit stealthed champions as well as those hidden in fog of war (revealing their position but not granting sight of them)
