Ekko should focus on efficient clears toward level 6 to unlock (R) for safer skirmishes and counterplay against Kha'Zix's burst and stealth.
Prioritize lane setups that allow (W) stuns from fog or brush to secure picks and control river entrances, limiting Kha'Zix's isolation damage.
Jungle Plan
Use full clear tempo to reach level 6 quickly and then look for picks using (W) stuns from fog or brush near objectives.
Invade or counter-jungle camps only when lanes have priority and Kha'Zix is visible on the opposite side to deny his scaling.
Prioritize vision control around dragon and Void Grubs, using (W) to zone and force Kha'Zix into grouped fights where he is weaker.
Danger windows
Respect Kha'Zix's level 6 stealth (R) and evolved abilities; avoid isolated jungle or river fights without vision or lane support.
Be cautious during low-health clears or forced smite fights where Kha'Zix's isolation burst can punish you.
Avoid contesting objectives if nearby lanes lack priority or cannot collapse quickly to support you against Kha'Zix's picks.
Early game
Start with a full clear or a five-camp clear into a lane with strong gank setup to maximize early pressure and avoid isolated fights where Kha'Zix excels.
Avoid early river fights unless nearby lanes have priority to prevent getting caught by Kha'Zix's isolation burst.
Contest first Scuttle only if your laners can move first, using (W) to control vision and zone Kha'Zix away.
Power spikes
Level 3 unlocks (Q)-(W)-(E) combo; use this to secure quick burst trades and force Kha'Zix back before he evolves key abilities.
Level 6 (R) grants safety and reset potential; use it to commit to picks or escape Kha'Zix's all-in attempts.
First completed AP burst item increases your damage and trade reliability; pressure objectives and waves more confidently after this.
Win conditions
Convert level 6 and item power spikes into aggressive picks using (W) stuns and (R) resets to snowball skirmishes.
Deny Kha'Zix free farm by invading with vision support when lanes can collapse, cutting off his isolation damage scaling.
Control vision and force grouped teamfights around dragon and Rift Herald where your burst and CC outvalue Kha'Zix's isolated damage.
