Kennen Build
the Heart of the Tempest
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.
