Jax vs Rengar

Updated Jun 6, 2026

Overview

Rely on scaling and dueling power to outlast Rengar's early invade and pick threat.
Prioritize controlled clears and vision around river brush to avoid Rengar's empowered (E) root and stealth picks.

Jungle Plan

Full clear and path through safe camps to delay Rengar's early invade pressure.
Contest Scuttle Crab only if your lanes have priority to prevent Rengar's brush control.
Track Rengar's jungle timers to counter-invade after he commits to a side or after his ultimate is down.

Danger windows

Early river fights near brush are risky due to Rengar's empowered root and stealth ultimate; avoid these without lane priority.
Invading or contesting camps without lane priority exposes you to Rengar's strong early dueling and pick potential.
Low-health clears or forced smite fights before level 6 increase vulnerability to Rengar's aggressive plays.

Early game

Start with a full clear to reach level 6 safely before contesting river or invading.
Avoid early river fights unless nearby lanes have priority to support counter-ganks.
Secure Scuttle only when lane priority and vision deny Rengar brush control.

Power spikes

Level 6 (R) grants durability and sustained damage, enabling extended fights when (E) is ready; use this to force trades.
Two-item spike significantly improves dueling and splitpush threat; force side-lane pressure to isolate Rengar.
Respect Rengar's early empowered (E) root and invade power before level 6 to avoid lethal skirmishes.

Win conditions

Use safe full clears and vision control to scale uninterrupted and deny Rengar early invades.
Leverage level 6 and item spikes to pressure side lanes and force Rengar into unfavorable 1v1s.
Coordinate with lanes to secure dragon and Rift Herald, using vision to prevent Rengar's picks and objective setups.
