Read from Irelia's seat: which stage windows this plan plays for against Sion.
This is Irelia's own plan; across 2,191 pooled games the lane is leaning Sion.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Sion | Sion walks up and pokes with charged Q and his armor-shred E while you only have Bladesurge and no stun to answer — concede and farm with Q resets. |
| Level 2 | Even / skill | W gives you the Defiant Dance damage-reduction channel to eat his charged Q chip, but his shield and poke keep the trade roughly even until your E comes online. |
| Level 3 | Irelia | Level 3 gives you E-stun into a Bladesurge reset — punish him the moment his charged Q whiffs or is on cooldown and he has no knockup to interrupt you. |
| Levels 4-5 | Irelia | Your Bladesurge stacks are building and an immobile, dashless Sion cannot kite your resets — you bully him in any straight-line trade. |
| Level 6 | Even / skill | Both his Soul Furnace shield-detonate and your Vanguard's Edge wall are live now, so the level-6 all-in is genuinely two-sided. |
| First item | Irelia | First-item reset uptime plus your max-stack on-hit shred out-DPS his still-low armor — this is your hardest all-in window. |
| Two+ items | Sion | He out-scales: three tank items plus the zombie passive and an AOE charged-Q knockup engage make him unkillable while you fall off — end early. |
Level 1 he just walks up and pokes with his charged Q and his E (an armor/MR-shred skillshot), and you only have Bladesurge with no stun to answer — so concede the first window, farm with Q resets off the casters, and never stand still long enough to eat a fully-charged Q knockup. The big rule all early is dodge the charge: his Q telegraphs hard, so sidestep it and his whole trade falls apart, because the uncharged version is a weak short-range hit with a small slow. At 3, the moment his charged Q whiffs or is on cooldown, E-stun him into a Q-reset and you win that exchange clean before he can detonate his W shield.
