Read from Sion's seat: which stage windows this plan plays for against Jax.
This is Sion's own plan; across 2,791 pooled games the lane is leaning Sion.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Sion | Your charged Q knockup is a genuine level-1 kill threat before Counter Strike is online, but Jax can sidestep the charge animation — the window is real only if he steps into range carelessly. |
| Level 2 | Even / skill | Your W-shield soaks his first two-ability trade at level 2, but you cannot reliably convert without your E; Jax can simply back off and reset, keeping the lane coin-flip. |
| Level 3 | Jax | His full kit at level 3 — Counter Strike dodges your Q auto, stuns you, and his Q-W burst fires before your shield detonates — tips the trade firmly in his favor. |
| Levels 4-5 | Jax | Counter Strike is 17s at rank 1 and dodges attacks, not abilities — your Q and E still land through it, but the stun eats your auto follow-up and your shield times out. |
| Level 6 | Even / skill | Unstoppable Onslaught closes the gap Counter Strike creates and opens a kill threat, but his R armor-and-MR aura means the all-in is still a skill read, not a free win. |
| First item | Jax | Trinity Force Sheen procs spike sharply enough to burst through your W-shield before you detonate it and stun you before the follow-up Q, making first item his hardest power window. |
| Two+ items | Sion | Two tank items and a Heartsteel stack means your W-shield absorbs his full on-hit burst cycle, E armor-shred dismantles his physical damage, and your zombie passive makes even a close duel costly for him. |
At level 1 you have a genuine threat — a full-charge Q knockup deletes his early window before Counter Strike is even active — but Jax simply sidesteps the slow charge, so do not stand still telegraphing it. Farm with Q tip at long range and watch for him to step up without his E ready; that is the one moment to hard-commit. Your W-shield absorbs his first trade if he walks onto you at level 2, but do not detonate it into his active Counter Strike or the shield expires for zero damage while he stuns you out of the follow-up. At level 3 his full kit is online and he wins most coin-flip trades: E dodges your Q auto follow-up, then stuns you into a Q-W burst sequence that your shield cannot fully block. Respect the level-3 all-in and let the wave come to you.
