the Heart of the TempestMage Marksman
More than just the lightning-quick enforcer of Ionian balance, Kennen is the only yordle member of the Kinkou. Despite his small, furry stature, he is eager to take on any threat with a whirling storm of shuriken and boundless enthusiasm. Alongside his master Shen, Kennen patrols the spirit realm, employing devastating electrical energy to strike down his enemies.
Mark of the Storm (KennenP)
Kennen's abilities add one stack of Mark of the Storm to their target for 6 seconds. If the target reaches 3 stacks, it is stunned for 1.25 seconds and Kennen gains 25 Energy.
The stun will be a diminished duration of 0.5 seconds if it occurs again within 6 seconds.
Thundering Shuriken (KennenQ)
Kennen throws a fast moving shuriken towards a location, causing damage and adding a Mark of the Storm to any opponent that it hits.
Electrical Surge (KennenW)
Kennen passively deals extra damage and adds a Mark of the Storm to his target every few attacks, and he can activate this ability to damage and add another Mark of the Storm to targets who are already marked.
Lightning Rush (KennenE)
Kennen morphs into a lightning form, enabling him to pass through units and apply a Mark of the Storm. Kennen gains movement speed when entering this form, and attack speed when leaving it.
Slicing Maelstrom (KennenR)
Kennen summons a storm that strikes at nearby enemy champions for magical damage.
Kennen is flimsy by nature - turn and attack him if he gets careless with Lightning Rush.
Consider playing a bit more cautiously around Kennen when you have a Mark of the Storm debuff. If he hits you with 3 Marks of the Storm, you will get stunned.
