Elise is an early ganker and dive jungler who must leverage her very high early pressure to snowball lanes before Rek'Sai's fast clear and tunnel ganks ramp up.
Focus on invading and punishing Rek'Sai before her first reset, using early wards to track her path and avoid full clears that let her scale.
Jungle Plan
Use early three-camp into gank or invade paths to deny Rek'Sai farm and force her off camps before she hits her power spike.
Fight for river control and first Scuttle when your lanes can assist to secure objective tempo and vision.
Track Rek'Sai's tunnel placements and be ready to counter-gank or cross-map when she commits to early ganks.
Danger windows
Rek'Sai's early tunnel ganks and knockup create high risk around her first clear and river fights; avoid overextending without vision or lane priority.
Be cautious contesting objectives without lane support as Rek'Sai can force smite fights or disengage with tunnels.
Low-health clears expose Elise to counter-invades; avoid extended fights if Rek'Sai is nearby or has better positioning.
Early game
Start with a three-camp clear into early gank or invade to capitalize on Elise's strong level 3 pressure.
Contest first Scuttle only if nearby lanes have lane priority to collapse and secure river control.
Avoid full clears against Rek'Sai's faster clear speed; prioritize early tempo and path toward lanes with kill potential.
Power spikes
Elise's level 3 with (E) cocoon and rappel enables lethal early ganks and dives; use this to force Rek'Sai off camps or secure kills.
Rek'Sai's early tunnel gank and (W) knockup create high threat windows; respect these by avoiding isolated river fights without lane backup.
Elise's early dueling burst outmatches Rek'Sai if you catch her out of position or before she completes her fast clear.
Win conditions
Convert early gank and invade pressure into lane leads by securing kills or forcing Rek'Sai off camps to deny her scaling.
Use superior early burst and (E) cocoon to secure first Scuttle and dragon control when lanes can assist.
Snowball leads by diving priority lanes early and maintaining river vision to prevent Rek'Sai from using tunnels for repeat ganks or counter-jungling.
