Lee Sin must leverage his very high early-game pressure to force river fights and invade before Briar's scaling kicks in.
Prioritize early tempo and creative gank angles to snowball and deny Briar's carry potential through early skirmishes.
Jungle Plan
Use level 3 power spike to path towards Briar's jungle with lane priority to force river skirmishes and invade camps.
Contest Scuttle Crab aggressively when lanes can assist, then transition to dragon or Rift Herald setups with (R) displacement.
Track Briar's first clear and counter-gank her early pressure by hovering near lanes with strong follow-up potential.
Danger windows
Beware of Briar's early invade timing when she has lane priority and can follow up her (Q) stun and (R) fear.
Avoid isolated river fights without vision or lane support, as Briar's high mobility and crowd control can punish overextensions.
Be cautious during forced smite fights on dragon or Rift Herald if Briar's team has better positioning or numbers.
Early game
Start with a path that hits level 3 quickly to enable strong invade or counter-invade plays around the river.
Fight for first Scuttle Crab only when nearby lanes have priority to secure vision and contest objectives.
Avoid committing to low-value fights without lane support, especially if Briar shows early pathing towards volatile lanes.
Power spikes
At level 3, Lee Sin gains full kit enabling strong dueling and invade threat; use this to force early fights before Briar scales.
At level 6, (R) unlocks powerful displacement to isolate targets or deny Briar's objective access; prioritize ganks and fights that capitalize on this.
Respect Briar's high scaling and sustained damage post-level 6; avoid extended fights where she can stick and outlast you.
Win conditions
Convert early river control and successful invades into dragon and Rift Herald objectives to snowball lanes.
Use (Q) and (W) mobility to create unexpected gank angles, focusing on lanes with priority to secure kills and reset tempo.
Deny Briar's scaling by forcing fights before she can safely extend, leveraging displacement (R) to isolate her or disrupt her engages.
