Prioritize isolation picks and fog control to punish Lillia's medium early pressure and slower clear speed compared to her very high clear and mobility.
Manage tempo by contesting isolated river fights and avoid grouped skirmishes where Lillia's sleep CC and AoE damage limit your dueling impact.
This is a snowball vs scale matchup where Kha'Zix must leverage early picks and objective control to deny Lillia's late-game teamfight influence.
Jungle Plan
Path to camps and jungle entrances that allow isolated picks using fog and (R) stealth before objectives.
Invade Lillia's jungle when she is low-health from fast clears and lanes cannot collapse quickly to punish her tempo farming.
Use vision to set up picks around dragon and Rift Herald, focusing on isolated targets to leverage your high objective control and deny Lillia's scaling.
Danger windows
Avoid isolated river fights before level 6 where Lillia's movement speed and sleep (E) can trap you.
Be cautious contesting objectives without vision control as Lillia's sleep (R) can turn fights globally.
Do not overextend or invade when nearby lanes lack priority, as collapsing on you removes your isolation advantage.
Early game
Start with a three-camp clear path that leads to early Scuttle control, focusing on camps near lanes that can isolate targets.
Avoid fighting Lillia early if she has lane priority to collapse; instead, track her pathing and counter-gank when she commits to ganks.
Contest first Scuttle only if nearby lanes have priority and can assist, otherwise secure isolated camps to build health and evolve key abilities.
Power spikes
At level 6, use (R) stealth to reposition for isolated picks before objectives, forcing Lillia to group and deny her sleep setups.
After your first damage item, aggressively invade and punish isolated Lillia camps before she can reset her clear tempo.
Respect Lillia's scaling into late game when her AP burst and sleep CC become more impactful in grouped fights.
Win conditions
Convert vision control and fog setups into isolated picks to snowball leads and secure early dragons and Rift Herald.
Deny Lillia free farm by invading her jungle camps when lanes cannot collapse, using your evolved (Q) and (E) resets.
Use your mobility and stealth to pressure side lanes and force Lillia into unfavorable grouped fights, limiting her AP scaling impact.
Tip: For Kha'Zix vs Lillia, read overview, trading pattern, and danger windows first for a fast Jungle lane check.
