Mark of the Storm

Innate: Kennen's abilities apply a stack of Mark of the Storm to enemies hit for 6 seconds, refreshing on subsequent applications and stacking up to 3 times.
The third stack against a target consumes them all to stun them for 1.25 seconds and restore 25 energy. The stun duration is reduced to 0.5 seconds if this occurs on the same target again within 6 seconds.
Slicing Maelstrom can apply only up to 3 stacks on a target.
