Favour timeline — the windows in Gnar's game plan

Read from Gnar's seat: which stage windows this plan plays for against Jax.

This is Gnar's own plan; across 803 pooled games the lane is leaning Jax.

StageFavouredWhy
Level 1GnarMini's ranged autos plus a single Boomerang win the first trade — Jax can't close range to punish until he levels Q, and his E doesn't block the Boomerang.
Level 2GnarRepeated Mini pokes plus the Boomerang slow let you chunk and shove before Jax has the items to E-dodge-and-stun his way back into the trade.
Level 3Even / skillYou can still kite his Q with the Boomerang slow and Hyper speed, but a Q-leveled Jax can dash onto your squishy Mini body and even the trade — genuinely a coin-flip.
Levels 4-5Even / skillVolatile Rage window: strong if Mega lines up for a Wallop or wall-ult, a liability if you're caught Mini when his Q-W-E commits.
Level 6Even / skillNo new spell at 6 for either of you here — your power is purely whether Mega is up, so the level is a wash on Rage timing.
First itemEven / skillYour Mini poke keeps the duel even, but his first Trinity/Bork starts to fuel longer trades where his E dodges autos and his W out-damages your poke.
Two+ itemsJaxJax out-scales hard: R plus stacked items let his E blank your autos and his W out-DPS you — group and play the wall-combo, don't solo him.

How to beat Jax as Gnar: the early game

Levels 1-3 are yours if you respect his E. Mini's ranged autos plus a Boomerang let you win the first trade at a range Jax can't match until he levels Q, and the Boomerang slows him so he can't stick. The one rule: never dump autos into a raised E (Counter Strike), or he eats the dodge and stuns you back. Poke when E is down, peel away with Hyper's third-hit move speed, and shove him off CS.
