Favour timeline — the windows in Jax's game plan

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

This is Jax's own plan; across 2,791 pooled games the lane is leaning Sion.

StageFavouredWhy
Level 1SionSion's fully-charged Q knockup chunks you and Counter Strike can't dodge an ability, so he owns the level-1 opener — just farm.
Level 2Even / skillOnce your combo is online you can punish a whiffed Q, but his Roar of the Slayer poke and Soul Furnace AoE still trade evenly through your dodge.
Level 3JaxFull Leap Strike + Empower + Counter Strike lets you recast-stun his next Q charge and grind the trade his immobility can't escape.
Levels 4-5JaxRanking the combo keeps Counter Strike up more often, and a totally immobile Sion can never disengage your extended trade.
Level 6Even / skillAt 6 it's a coinflip: your Grandmaster-at-Arms resists win the long duel, but a landed charged Q plus his shield can still even the exchange.
First itemJaxYour every-third-hit on-hit ramp out-damages his Soul Furnace shield before he has two tank items — force the all-in now.
Two+ itemsSionFull-tank Sion reclaims it: his zombie passive second life and stacked resists make him a frontline you can't solo-burst.

How to beat Sion as Jax: the early game

Sion's whole early game is the charged Q. Your Counter Strike (E) dodges his autos but does nothing to the knockup itself, and a full-charge Q chunks you hard — so at level 1 don't walk into Q range to throw a Leap Strike he can punish; just farm. From 2-3 you flip it: bait or sidestep the Q, then Q-in, W-Empower the landing hit, and hold E to dodge his auto follow-up before recasting to stun — and that stun interrupts his next Q charge. His Roar of the Slayer poke and Soul Furnace AoE still hit you through your dodge (E only blanks basic attacks), so only commit when his Q is down.
