Lee Sin must leverage his very high early game pressure to force river fights and invade before Evelynn hits level 6.
Prioritize early tempo and skirmishes to deny Evelynn's safe full clears and delay her scaling power spike.
Jungle Plan
Invade Evelynn's jungle aggressively before level 6 when she is vulnerable and has low dueling power.
Use creative ward-hop angles with (W) to set up unexpected ganks on pushed lanes and force Evelynn to respond.
Prioritize controlling river vision and contesting Scuttle to limit Evelynn's post-6 flank routes and objective access.
Danger windows
Beware Evelynn's level 6 power spike when she gains camouflage and pick potential; avoid isolated river fights without vision.
Avoid low-health jungle clears that make you vulnerable to Evelynn's counter-invades or ganks.
Be cautious contesting objectives if Evelynn's lanes lack priority or vision control, as she can flank and pick off targets.
Early game
Start with a three-camp clear that allows reaching level 3 quickly to contest or invade Evelynn's jungle.
Fight for first Scuttle Crab only if nearby lanes have priority to back up river control.
Avoid extended fights if low on health after clears; use (W) mobility to reposition or escape invades.
Power spikes
Level 3 unlocks Lee Sin's full kit, enabling strong dueling and invade potential; path toward Evelynn when lanes can move first.
Level 6 grants (R) for displacement, allowing isolation of Evelynn or disruption of her objective attempts; use it to force fights or peel.
Evelynn's major spike is post-6 stealth and AP scaling; respect her flank threat and avoid isolated fights without vision.
Win conditions
Convert early invade and river control into securing first dragons and Rift Herald to snowball team advantage.
Use (Q) and (W) mobility to create gank pressure on priority lanes, forcing Evelynn to play defensively.
Deny Evelynn safe farm and scaling by invading and counter-jungling when lanes have priority, preventing her from reaching mid and late game power spikes.
