Use Lillia's superior clear speed to maintain jungle tempo and reach AP item spikes before Rek'Sai can snowball early pressure.
Avoid early river fights before movement speed stacks are active to prevent Rek'Sai's strong early gank and invade threat from punishing low-health clears.
Jungle Plan
Start with a full clear to leverage Lillia's very high clear speed and avoid early Rek'Sai invades.
Contest Scuttle when your lanes have priority and Rek'Sai is visible on the opposite side of the map.
Use vision and lane priority to counter-jungle Rek'Sai after her early three-camp clear and gank attempts.
Danger windows
Rek'Sai's early three-camp clear into gank creates high invade and counter-gank risk before Lillia reaches item spikes.
Low-health clears before movement speed stacks are active leave Lillia vulnerable to Rek'Sai's burst and knockup (W).
Forced smite fights at early dragon or Rift Herald can be dangerous if Rek'Sai has lane priority or tunnel vision on objectives.
Early game
Full clear quickly and reset tempo to hit early AP spikes while avoiding Rek'Sai's level 3 three-camp into gank paths.
Fight for first Scuttle only if nearby lanes have priority and can support counter-gank to negate Rek'Sai's tunnel gank angles.
Prioritize safe camp cycling around lanes that can follow your (E) sleep setup to maximize gank threat and objective control.
Power spikes
Lillia's major power spike comes with her first AP item, enabling stronger sleep (E) setups and objective control; use this to force fights around dragon.
Rek'Sai's early power spike is her level 3 three-camp clear into gank; respect this by avoiding low-health clears and risky river fights.
Lillia's (R) global sleep is a late scaling spike; use it to initiate grouped objective fights and secure teamfight advantages.
Win conditions
Out-clear Rek'Sai to maintain jungle tempo and hit AP scaling spikes first, denying her snowball opportunities.
Use (E) sleep setups combined with lane priority to secure kills and objective control around dragon and Rift Herald.
Track Rek'Sai's tunnel paths and gank timing to counter-gank effectively and punish overextensions, turning tempo into teamfight advantages.
