Prioritize objective control and repeated ganks using (W) for long-range engage and (Q) for sustain and fast clears.
Avoid isolated duels with Rek'Sai and instead fight when you have lane CC or (W) numbers advantage to punish her early aggression.
Jungle Plan
Use (W) from fog for surprise ganks and force Rek'Sai's lanes to ward deeper, opening up objective setups.
Convert successful ganks into immediate dragon or Rift Herald attempts using (Q) plus Smite for secure control.
Track Rek'Sai's pathing to counter-gank her early pressure and deny her tempo advantage through river vision and lane priority.
Danger windows
Beware Rek'Sai's early invade and tunnel gank attempts around level 3; maintain vision and lane priority to reduce counter-gank risk.
Avoid isolated river fights where Rek'Sai's knockup and mobility can punish you without lane support.
Be cautious during forced smite fights on objectives if Rek'Sai's lanes lack pressure and cannot assist.
Early game
Start with a full clear using (Q) to maintain health and tempo, then use (W) to gank overextended lanes or set up river control.
Fight for first Scuttle only if nearby lanes have priority to support counter-ganks and objective setups.
Avoid early isolated fights; path to gank or counter-invade when Rek'Sai shows on the opposite side of the map.
Power spikes
At first dragon or Rift Herald spawn, use (Q) plus Smite to secure objectives and force Rek'Sai into contested fights.
At level 6, layer (R) after (W) or allied CC to zone and burst enemies caught in your crowd control chain.
Respect Rek'Sai's early level 3-4 power spike with tunnel ganks and knockup; avoid extended isolated fights during this window.
Win conditions
Use fast clear speed and (Q) sustain to maintain jungle tempo and pressure opposite side objectives when Rek'Sai commits elsewhere.
Leverage (W) gank angles and lane CC to create numbers advantages for successful ganks and objective starts.
Deny Rek'Sai free farm by tracking her pathing and counter-jungling when lanes have priority, converting tempo leads into dragon and Rift Herald control.
