Amumu must survive Rek'Sai's early high-pressure invade and gank attempts by securing a controlled first clear and defensive wards.
This is a snowball vs scale jungle matchup where Amumu aims to reach teamfight power spikes and force grouped fights around objectives.
Jungle Plan
Prioritize securing first Scuttle only when nearby lanes have priority to avoid risky fights.
Path toward lanes that can follow your (Q) engage and contest dragon or Void Grubs after hitting level 6.
Counter-gank Rek'Sai's early tunnel ganks by tracking her pathing and positioning near volatile lanes and objective entrances.
Danger windows
Rek'Sai's early invade and tunnel gank attempts create high danger around level 3; avoid isolated river fights without lane priority.
Be cautious during low-health clears when Rek'Sai can force smite fights or counter-jungle.
Avoid contesting objectives if Rek'Sai has nearby tunnel access and lanes lack priority, as she can quickly collapse.
Early game
Start with a full clear or three-camp path toward a lane with crowd control to enable early ganks with (Q).
Avoid early river fights without lane priority to prevent Rek'Sai's strong early dueling and invade potential.
Use defensive wards on jungle entrances to track Rek'Sai's tunnel paths and prevent surprise invades.
Power spikes
At level 6, use (Q) and (R) to force grouped fights and secure objectives, forcing Rek'Sai to respect your lockdown.
Rek'Sai is strongest early with high clear speed and dueling; respect her early levels by avoiding isolated fights.
Amumu's teamfight value rises sharply post-level 6, so focus on reaching this spike safely to outscale Rek'Sai.
Win conditions
Convert safe early clears and defensive vision into level 6 power spikes to control dragon and Rift Herald fights.
Use (Q) and (R) to initiate grouped fights around objectives, denying Rek'Sai's early tempo and snowball potential.
Track Rek'Sai's tunnel usage to counter-gank and punish her early pressure, then leverage superior objective control to scale into late game teamfights.
