Rengar thrives on early invades and brush control to punish Darius's low mobility and limited escape options.
Prioritize denying Darius jungle camps and controlling river brush to secure Scuttle and objective vision for tempo advantages.
Jungle Plan
Prioritize early river brush control to contest first Scuttle when your lanes can collapse, then look to invade Darius's jungle if he is on the opposite side.
Use your empowered (E) root and (R) stealth to create picks around dragon or Rift Herald setups after denying camps.
Convert tempo leads into securing Void Grubs, dragon vision, and counter-jungling to deny Darius scaling and objective control.
Danger windows
Respect Darius's early invade windows when he can pull you with (E) and force extended trades near his passive stacks.
Avoid isolated river fights or Scuttle contests when your mobility or Smite is down, especially if lanes lack priority.
Be cautious contesting objectives if Darius's nearby lanes can collapse first or if you have low health after clears.
Early game
Start with a three-camp clear that leads into river brush to prepare for an early Scuttle contest only if nearby lanes have priority.
Avoid fighting for Scuttle or invading if lane priority is lost or Darius is tracked on your side to prevent risky isolated fights.
Use brush paths to approach enemy camps safely and capitalize on Darius's predictable pathing for counter-jungling opportunities.
Power spikes
Level 6 unlocks your ultimate (R) pick threat, enabling lethal ganks and forcing Darius to respect fog and brush angles.
Your early dueling power near brush allows you to punish Darius before he completes his first bruiser item, which increases his durability.
Post first item spike, maintain pressure to deny Darius extended fights where his passive stacks become dangerous.
Win conditions
Use brush control and your ultimate to create picks that lead to dragon or Rift Herald advantages.
Deny Darius jungle camps through timely invades when your lanes have priority to delay his scaling.
Apply repeated gank pressure post-6 to snowball lanes and secure objectives with vision control around river and jungle entrances.
