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.
Kha'Zix passively marks enemies that are isolated from nearby allies. Taste Their Fear deals physical damage to a single target. Damage increased on isolated targets. If he chooses to Evolve Enlarged Claws, this deals extra bonus damage against isolated targets. Kha'Zix also gains increased range on his basic attacks and Taste Their Fear.
Kha'Zix fires exploding spikes that slow and deal physical damage to enemies hit. Kha'Zix is healed if he is also within the explosion radius. If he chooses to Evolve Spike Racks, Void Spike fires three spikes in a cone and Void Spike's slow effect is increased.
Kha'Zix leaps to an area, dealing physical damage upon landing. If he chooses to Evolve Wings, Leap's range increases dramatically. Also, on champion kill or assist, Leap's cooldown resets.
Each rank allows Kha'Zix to evolve one of his abilities, giving it a unique additional effect. When activated, Void Assault stealths Kha'Zix, triggers Unseen Threat, and increases Movement Speed. If he chooses to Evolve Active Camouflage, Void Assault can be cast three times and stealth duration increased.
The Void grows, and the Void adapts—in none of its myriad spawn are these truths more apparent than Kha'Zix. Evolution drives the core of this mutating horror, born to survive and to slay the strong. Where it struggles to do so, it grows new, more effective ways to counter and kill its prey. Initially a mindless beast, Kha'Zix's intelligence has developed as much as its form. Now, the creature plans out its hunts, and even utilizes the visceral terror it engenders in its victims.
