Use Lee Sin's very high early pressure and mobility to contest river and deny Viego's scaling by forcing fights before he reaches key item breakpoints.
Prioritize early river control and gank tempo to snowball lanes and limit Viego's safe jungle access, leveraging Lee Sin's strong level 3 and 6 power spikes.
Jungle Plan
Prioritize early river control and vision to set up for dragon or Rift Herald fights, using (Q) and (R) to isolate targets and deny Viego's objective access.
Invade and counter-jungle camps when Viego's health or cooldowns are low, but only if nearby lanes have priority to support or counter-gank.
Use tempo resets after successful ganks to keep your camps from falling behind and maintain pressure before Viego scales.
Danger windows
Be cautious contesting river scuttle crab around levels 3-6 where Viego can counter-invade with ultimate ready.
Avoid isolated fights in narrow jungle paths or river bushes where Viego can capitalize on resets and (W) stun.
Respect enemy laners' roam timers that enable counter-ganks when you invade or attempt aggressive plays.
Early game
Start with a three-camp clear to hit level 3 before Viego and immediately contest the nearest Scuttle Crab if your lanes have priority.
Avoid full invades without lane vision or support, but punish Viego's slower clears by invading when his key cooldowns are down.
Use (W) mobility to path around Viego and position for counter-invades or early river skirmishes.
Power spikes
Spike at level 3 with full kit access to contest river and force early fights; path to enemy jungle when lanes can move first.
Spike at level 6 when (R) enables pick potential and objective denial; use it to isolate priority targets or disrupt Viego's smite attempts.
Respect Viego's level 6 (R) reset potential and avoid fights when his ultimate is available and lanes cannot support you.
Win conditions
Convert early jungle pressure and vision control into securing dragons and Rift Herald before Viego reaches item power spikes.
Use gank windows post-level 3 to snowball lanes and deny Viego safe jungle access, forcing him into risky plays.
Maintain river control and track Viego's pathing to punish overextensions and prevent his reset chains in skirmishes.
