Use Rengar's superior early invade resistance and brush control to pressure Diana's jungle entrances and deny her tempo.
Focus on controlling river brush to contest Scuttle and objectives, leveraging Rengar's strong dueling and pick potential to create numbers advantages.
Jungle Plan
Prioritize invading Diana's jungle when lanes have priority to deny her fast clear tempo and delay her level 6 spike.
Use brush control to set up picks with (R) before initiating dragon or Rift Herald fights.
Track Diana's pathing to counter-gank her early pressure and secure river vision to maintain objective control and tempo.
Danger windows
Respect Diana's level 3 (Q)+(E)+(W) burst combo when she has lane priority or minion support.
Avoid isolated river fights before securing brush control, as (E) mobility and (Q) burst punish poor positioning.
Be cautious contesting objectives when Diana has first AP item and (R) available due to her damage spike.
Early game
Start with a path that secures brush-heavy camps to maximize empowered ability usage and set up early invades.
Contest first Scuttle only if nearby lanes have priority to cover your exit and counter Diana's objective focus.
Avoid extended fights in open river early, as Diana's mobility and AoE clear punish overcommitments.
Power spikes
Rengar's level 3 empowered ability unlock gives a strong dueling edge near brush; force Diana off camps then.
Respect Diana's level 6 (R) all-in threat by holding defensive tools and punish after it's spent.
Leverage post-6 ultimate picks to snowball leads and deny Diana's mid-game teamfight impact.
Win conditions
Convert early brush control and successful invades into denied camps and objective numbers advantages.
Use (R) stealth picks to create favorable fights around dragon and Rift Herald, forcing Diana reactive.
Maintain river vision and track Diana's cooldowns to counter-gank and pressure her post-level 6 scaling window effectively.
