Favour timeline — the windows in Jax's game plan

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

StageFavouredWhy
Level 1OrnnOrnn owns level 1 — he can Bellows Breath (W) the fire cone over you for Brittle and chip while you have only Leap Strike and no Counter Strike to dodge anything.
Level 2Even / skillBoth add a point and it stays close: he answers your Q poke with a W cone and a Brittle-charged auto, you answer with Empower — neither lands a decisive trade.
Level 3JaxFull Counter Strike online: hold E so his auto-attacks whiff, recast to stun, then Leap in and Empower to win the extended trade — just not against his W.
Levels 4-5JaxRanked Counter Strike plus Empower runs a pre-item Ornn over — the moment his Searing Charge (14s) is on cooldown he has no knockup to break your trade.
Level 6Even / skillIt's a coinflip on his cooldowns: dodge the E knockup and you lead, but eat the pillar or his held R and the trade flips, so this window is genuinely even.
First itemOrnnHis first tank item plus the Brittle-into-knockup combo blunts your on-hit ramp, and he paid nothing for it — Ornn edges the one-item duel back.
Two+ itemsOrnnOrnn out-scales hard — self-itemized into an unkillable frontline, and his R ram knockup wins teamfights while your side-lane 1v1 stops mattering.

How to beat Ornn as Jax: the early game

At level 1 Ornn out-pokes you: he can Bellows Breath (W) the fire cone over you for Brittle and free damage while you only have Leap Strike and no Counter Strike to answer, so concede the opener and farm. Your turn comes at 3 — with E up you can hold it through his auto-attacks so they whiff, recast for the stun, then Q in and Empower the trade. The trap is that Counter Strike does NOT dodge his Bellows Breath cone (it is ability damage, not a basic attack) and it does nothing against his E pillar, so the lane hinges on baiting his Searing Charge knockup before you all-in.
