Use Lee Sin's superior early game pressure and mobility to invade Sejuani and deny her safe farm and scaling opportunities.
Prioritize river control and first Scuttle to leverage Lee Sin's early duel strength and disrupt Sejuani's objective setups.
Jungle Plan
Path aggressively toward river and enemy camps when lanes can pressure, forcing Sejuani off camps and denying her tempo.
Contest first Scuttle only when nearby lanes have priority to avoid overcommitment and counter-ganks.
Use successful ganks to reset tempo and keep your camps up to maintain pressure and deny Sejuani scaling.
Danger windows
Beware of Sejuani's level 6 all-in potential around isolated river fights and contested objectives; avoid fighting alone.
Avoid low-health jungle clears where Sejuani can force smite fights or counter-invade with her tankiness and CC.
Respect enemy lanes that push early, as they enable Sejuani to collapse quickly on your invades or counter-ganks.
Early game
Start with a fast clear aiming to reach level 3 quickly and contest or secure the first Scuttle crab to deny Sejuani vision and control.
Look for early invades when nearby lanes have priority, but disengage if Sejuani shows strong early aggression or if lanes lack pressure to back you up.
Avoid extended fights before level 6 where Sejuani's crowd control and tankiness can turn trades against you.
Power spikes
Exploit Lee Sin's level 3 power spike by invading and forcing early river fights before Sejuani can complete her full clear.
Respect Sejuani's level 6 spike when her (R) enables long-range engage and strong crowd control; avoid forced smite fights during this window.
After level 6, use (R) displacement to isolate targets and contest objectives with superior mobility and pick potential.
Win conditions
Convert early jungle pressure and successful invades into objective control by securing dragons and Rift Herald when Sejuani is denied or out of position.
Use superior pathing and creative gank angles to snowball lanes and force Sejuani behind in farm and experience.
Maintain river vision and contest Scuttle crabs to limit Sejuani's ability to start fights and control key objectives.
