Rengar's strength lies in early invades and brush control to deny Warwick's sustain and dueling power.
Prioritize disrupting Warwick's jungle tempo through targeted invades and leveraging Rengar's superior mobility and stealth for picks.
Jungle Plan
Use brush-heavy paths to approach Warwick's jungle entrances for invades when nearby lanes have priority.
Contest first Scuttle only if you have lane support to collapse and deny Warwick early objective control.
Convert successful invades into vision and tempo for dragon or Rift Herald setups, and prioritize counter-jungling when Warwick is tracked on opposite side.
Danger windows
Respect Warwick's level 3 dueling power, especially when (E) fear or (R) suppression are available.
Avoid isolated river fights when Warwick has lane priority or vision control.
Do not contest smite fights without vision and lane support due to Warwick's sustain and dueling strength.
Early game
Start with a three-camp clear optimized for quick level 3 to contest or secure first Scuttle when nearby lanes hold priority.
Only contest river Scuttle if lanes can collapse first; otherwise path to opposite side camps to avoid risky fights.
Avoid isolated early fights without vision as Warwick's sustain and fear make him dangerous in extended duels.
Power spikes
Avoid extended fights at Warwick's level 3 when his full kit and sustain favor him.
Use Rengar's level 6 (R) stealth picks to create numbers advantages before major objectives.
Punish Warwick before he completes his first dueling or tank item by invading or forcing fights.
Win conditions
Use brush control and (R) stealth to create picks that deny Warwick camps and limit his scaling.
Translate jungle tempo into securing dragon and Rift Herald with lane priority to force Warwick reactive.
Counter-jungle Warwick when his location is tracked to deny farm and force unfavorable fights.
