Unseen Threat (Passive): When Kha'Zix is not visible to the enemy team, he gains Unseen Threat, causing his next basic attack against an enemy champion to deal bonus magic damage and slow.
Taste Their Fear: Deal physical damage to a single target. Damage against isolated targets is significantly increased. Kha'Zix passively marks enemies that are isolated from nearby allies.
Evolving claws increases damage to isolated targets even further. Kha'Zix also gains increased range on both Taste Their Fear and his basic attack.
Void Spike: Kha'Zix fires spikes that explode on contact, dealing physical damage to all nearby enemies. Kha'Zix is healed if he is within the explosion radius.
Evolving spike racks causes Void Spike to fire three projectiles in a cone. Spikes will also apply Unseen Threat to all enemies caught within the area of effect.
Leap: Kha'Zix leaps to an area, dealing physical damage to enemies in the area he lands.
Evolving wings increases Leap's range dramatically and causes a kill or assists to refresh the cooldown of Leap.
Void Assault: Each rank of Void Assault allows Kha'Zix to evolve one of his active abilities, granting it an additional effect. Upon activation, Kha'Zix enters stealth and gains Unseen Threat, increasing Movement Speed. Kha’zix can cast Void Assault again for a short time after activation.
Evolving active camouflage allows Kha’Zix to cast Void Assault three times over the course of its duration and reduces any damage he sustains while in stealth.
