Use turret zones to control the lane and force Gnar to farm under pressure, denying his safe scaling opportunities.
Maintain high lane pressure by setting turrets early and punishing Gnar's melee approaches to prevent him from freely stacking Rage or engaging effectively.
Trading pattern
Let your turrets define the fight and use (E) to lock down Gnar when he approaches, then layer (W) and your upgraded ability (R) for burst or control.
Punish Gnar's mini form when his (E) is down by aggressively using turret zones and (E) stun to prevent his kiting and poke.
Avoid fighting away from your turrets and respect Gnar's mega form crowd control; trade primarily when your (E) is ready and turrets are active.
Danger windows
Be cautious when Gnar's Rage is near mega form and his (E) is available, as he can engage with durable crowd control.
Avoid extended trades or fights when your turrets are cleared or (E) is on cooldown, as your zone control and anti-engage weaken.
Watch for Gnar's mega form (R) wall stun near terrain; maintain spacing to avoid being trapped and stunned in turret zones.
Early game
Establish multiple turrets before level 3 to maximize your zone control and punish Gnar's attempts to farm or trade.
Hold (E) to stun Gnar when he tries to engage or walk into turret range, avoiding using it casually to bait his commitment.
Avoid pushing the wave without vision to prevent being vulnerable to Gnar's medium mobility and potential follow-up engages.
Power spikes
At level 3, your full turret, (W), and (E) combo is online; use this power spike to assert lane control and punish Gnar's melee advances.
At level 6, choose your (R) upgrade based on the fight: use upgraded (E) for anti-dive control or upgraded (W) for burst to punish Gnar's mega form engages.
Respect Gnar's level 6 mega form with (R) and his ability to stun near terrain; back off before he transforms or fight after the mega form expires.
Win conditions
Win by maintaining turret zones that force Gnar to farm under pressure and punish his melee approaches with (E) stuns and layered (W) or upgraded spells.
Deny Gnar's ability to safely stack Rage and transform by controlling wave state and timing your trades around his cooldowns.
Use your upgraded (R) strategically to either deny Gnar's dives or burst him down during objective setups or all-in windows.
