Read from Sion's seat: which stage windows this plan plays for against Irelia.
This is Sion's own plan; across 2,191 pooled games the lane is leaning Sion.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Sion | A pre-charged Q threatens a knockup before she has her E stun — she has no reliable in-trade reset at level 1 and must respect the ground-slam telegraph. |
| Level 2 | Even / skill | Both kits come online simultaneously: your W-shield can block her E stun's burst, and her Defiant Dance can block yours — genuine parity in short trades. |
| Level 3 | Irelia | With all three basic abilities she chains Q resets through a minion wave to stack Ionian Fervor before her E stun, winning sustained trades on her terms. |
| Levels 4-5 | Irelia | Ionian Fervor at max stacks is attack speed and bonus on-hit, not armour shred, and Bladesurge resets keep her on you through the wind-up — the big wave is hers. |
| Level 6 | Even / skill | Your R gives you all-in threat she must respect, but her E is back up and her Trinity Force timing approaches — neither side can force a clean kill. |
| First item | Irelia | Trinity Force Irelia's burst per reset cycle matches your W-shield cooldown; every E stun she lands goes unanswered while your Q is charging. |
| Two+ items | Sion | Heartsteel Sion's HP makes your W-shield absorb her burst, your E shreds her lightly-armored frame, and your Passive zombie forces her off every extended trade. |
At level 1, a pre-charged Q is your only legitimate threat — hold it at the brush edge and bait her forward before she hits level 2. The moment she hits level 2 and gets her W (Defiant Dance), she can block the burst of your full-charged slam, removing your best trading tool entirely. Keep the wave even or slightly pushed so the minion count is never large enough to fuel her Q resets into you; deny her the lane geometry she needs to stack Ionian Fervor safely. If she tries to step up to auto you, fire the charged Q into her approach — the knockup duration is long enough that you can follow with E armor-shred before she lands.
