Use Rengar's strong early dueling and brush control to invade Vi's jungle and deny camps before she can gank or contest objectives.
Prioritize river brush control to contest Scuttle and set up picks with (R) before dragon or Rift Herald fights.
Jungle Plan
Path through brush-heavy routes to maximize surprise and invade only when lanes can collapse or Vi is tracked elsewhere.
Fight for first Scuttle only if nearby lanes can move first and use (R) stealth picks to secure dragon or Herald setups.
Convert tempo leads into counter-jungle camps and vision control around dragon and Rift Herald to deny Vi's objective access and scaling.
Danger windows
Respect Vi's early level 2-3 gank threat when (Q) dash is available and lanes lack priority.
Avoid isolated river skirmishes without vision or lane support, especially when your mobility or Smite is down.
Be cautious contesting objectives if Vi's lanes have priority or if you have low health after clears, as forced Smite fights favor Vi's lockdown and damage.
Early game
Start with a three-camp clear through brush to hit level 3 quickly and look to contest the first Scuttle when your lanes have priority.
Avoid open river fights early unless you have vision and lane support to punish Vi's medium invade resistance.
Use brush control to set up counter-invades or contest camps when Vi is pathing opposite side.
Power spikes
Level 3 empowers Rengar's dueling near brush, enabling aggressive counter-jungling before Vi can gank.
Level 6 unlocks ultimate stealth, increasing gank threat and pick potential to force Vi to respect fog and reduce her objective control.
First completed damage item boosts burst, allowing Rengar to punish Vi's lockdown attempts and medium early fight resistance.
Win conditions
Use brush control and (R) picks to deny Vi's jungle camps and force reactive clears.
Translate early tempo into dragon and Rift Herald control by setting vision and forcing Vi into unfavorable fights.
Leverage cross-map trades and counter-ganks when Vi commits to ganks, using superior dueling and stealth to snowball leads and deny her scaling.
