Build a first contact you can exit

0:00–8:00, especially the first clear through the 2:55 Scuttler and the first available objective window

Start with a conditioned route: full clear toward a lane with no setup or a difficult early duel; choose three or five camps only when a real level-3 window and nearby follow-up exist. The first camps spawn at 0:55, Krugs and Gromp at 1:07, and Scuttle at 2:55, so finish near a planned gank or river contest rather than wandering. Use Flurry between spells when safe, and do not spend Energy and both dash options merely to reveal yourself. If an early play succeeds, take the nearest camp, wave, plate opportunity or objective; if it fails, return to the clear instead of repeating the same lane.

Path

Path toward a real collapse

If your champion wins early contact, at least one nearby lane can rotate, and your first clear ends on that side, then choose a three- or five-camp route toward that lane. Use a full clear instead if the lane lacks setup or the level-3 fight is unfavorable; Lee Sin's route must fund pressure without abandoning his Energy and Flurry cycles.

With Lee Sin

• If Lee Sin is on your team, make his first contact easier rather than demanding a blind engage. Push the nearby wave before an invade or river fight; if the enemy is forced to last-hit or has used their escape, hold your crowd control for the moment his Sonic Wave connects.
• Stay within one screen when he is threatening a dive, but do not stand directly behind the target he may kick. If he marks a target and your follow-up is ready, commit to that target; if the mark misses, let him disengage instead of chasing into an isolated 1v2.
• At objectives, help him establish the approach during the available setup window. If the enemy jungler is visible away from the pit, zone the entrance while Lee Sin holds Smite; if the enemy enters the last-hit window, protect his access or help force the jungler out before the finish.
• When Lee Sin is ahead, give him first access to the side where your lane has priority and convert his pressure into plates, camps or a tower. When he is behind, do not ask for repeated ganks into a stable lane; help him safely reach the next camp cycle and group for a clear numbers advantage.
• In teamfights, choose whether he is your second-wave diver or your peel tool before the fight starts. If your carry is the win condition and the enemy has a diver, Lee Sin's Safeguard and Dragon's Rage may create more value protecting the carry than chasing the enemy backline.
