Jungle
Count Unseen Threat procs, not just Qs: open with the stealth auto from fog or R, cash the slow with Q and W, then disappear again if the fight stays live, because real Kha'Zix damage comes from passive re-arms as much as from the first burst .
Choose evolutions by the kind of contact the game is giving you—Q when camp and river scraps stay isolated, R when you need the vanish-touch-drop-vision-passive-again pattern, and W when grouped comps force you to reveal and slow one player out of the pack .
Kha'Zix is best at punishing handoff moments—jungler walking into a dark quadrant, carry arriving late to river, side-laner taking one more wave—and the recent data backs that he is much less comfortable in flat even states than steadier assassin junglers, so the goal is to reach evolve with pace and hunt those broken-sightline transitions .
Take W evolve when the game has stopped giving you clean isolated touches and you need to keep shaping fights before you can finish them. It gets much better when carries are glued to peel, when brush checks and river standoffs decide who can move first, or when your job is to slow one player hard enough that they become the delayed target a second later. It is also a good answer when your team needs help catching, disengaging, or revealing movement through fog. If fights still look like scattered river scraps, invade duels, or side catches, Q or R usually gives you more.
Nearby enemies that are Isolated from their allies are marked. Kha'Zix's abilities have interactions with Isolated targets.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 them for a few seconds.
Deals physical damage to the target. Damage increased on Isolated targets. If he chooses to Evolve Reaper Claws, this refunds a percent of it's cooldown against Isolated targets. Kha'Zix also gains increased range on his basic attacks and Taste Their Fear.
Kha'Zix fires exploding spikes that 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 now fires three spikes in a cone, slow enemies hit, and reveals enemy champions hit for 2 seconds. Isolated targets are slowed for extra.
Kha'Zix leaps to an area, dealing physical damage upon landing. If he chooses to Evolve Wings, Leap's range increases and the cooldown resets on champion kill or assist.
Each rank allows Kha'Zix to evolve one of his abilities, giving it a unique additional effect. When activated, Kha'Zix becomes Invisible, triggering Unseen Threat and increasing Move Speed. If he chooses to Evolve Adaptive Cloaking, Void Assault gains increased Invisibility duration, and an additional use.
