Use medium lane pressure to force Gnar into uncomfortable trades and deny his passive scaling windows.
Manage short trades around your passive health regen to survive Gnar's poke and avoid extended fights where he excels.
Trading pattern
Engage with (Q) to silence Gnar's disengage or poke, then quickly follow with (E) and retreat before he can counterattack.
Punish Gnar when his (E) hop is down to close distance and force trades.
Avoid trading when your passive is low or (Q) is baited, as Gnar can kite and punish extended fights.
Danger windows
Be cautious when Gnar's Rage is near mega form and he can engage with (E) or (R) near terrain.
Avoid extended trades after your (Q) silence ends, as Gnar can kite and punish you.
Watch for Gnar's mega (W) stun and (R) wall stun during his transformation; disengage or back off to avoid hard CC.
Early game
Focus on short (Q) silence trades followed by (E) damage, then back off to recover health before Gnar can retaliate.
Avoid prolonged trades especially when (E) is available to kite or disengage.
Use bush angles to approach safely and reduce Gnar's ability to poke from range.
Power spikes
Level 6: Use (R) execute to finish off low-health Gnar after chipping him with short trades.
First bruiser or tank item: Repeat controlled trades confidently, absorbing Gnar's poke better.
Respect Gnar's level 6 mega form (R) and (W) stun windows; avoid fighting near walls when his mega form is ready.
Win conditions
Use short (Q)+(E) trades to chip Gnar's health and build execute pressure with (R).
Exploit windows when (E) is down to close distance and force fights.
Survive early poke by spacing trades and passive regen, then leverage your level 6 execute and tankiness to win side-lane fights and pressure objectives.
