How to win lane as Sion against Sejuani · 49.82% win rate over 1,140 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Level 1 is decided by who can auto-trade without getting Frost-stacked into Permafrost — neither side has a clean opener, so last-hit safely and map her stun pattern before committing. |
| Level 2 | Even / skill | Your W-shield absorbs Winter's Wrath W ticks and makes short trades favorable, but Permafrost E is already live — bait it before charging Q or she stuns you mid-channel. |
| Level 3 | Sejuani | Sejuani's full kit (Q dash, W Frost stack, E Permafrost stun) is online and her engage pattern is complete before yours lands — she can close and stun a charging Q reliably at level 3. |
| Levels 4-5 | Even / skill | Both kits are online but neither has a meaningful item spike — the lane is a pattern-management window, trade around Permafrost's cooldown and freeze for the CS lead. |
| Level 6 | Even / skill | Sejuani's Glacial Prison R turns any all-in lethal: she Arctic Assaults, W-stacks, Permafrost stuns, then R catches you — don't be low HP at 6 and use Unstoppable Onslaught to bail if needed. |
| First item | Sejuani | Sejuani's Sunfire/Frostfire Winter's Wrath percent-HP tick scales with her tank items and starts outpacing your Heartsteel HP gains in sustained brawls — she edges the contested first-item window. |
| Two+ items | Even / skill | Two items each, both sides are enormous frontlines — your zombie passive guarantees one last charged-Q knockup even through death, keeping the brawl genuinely even in prolonged teamfights. |
Level 1 is a genuine coin flip — Sejuani's passive Frost stacks build on autos and her W Winter's Wrath tick, so she can set up a Permafrost stun without spending a single extra ability. Don't auto-trade freely; last-hit at Q range and let her show the Permafrost pattern before you commit. At level 2 your W-shield absorbs her Winter's Wrath damage and makes short trades cost her more, but she hits level 3 with the same Frost stacking threat. At level 3 she has her full kit too — Arctic Assault Q to close, W to stack Frost, E to stun — so her engage pattern is complete before yours. Respect that: charge Q from brush angles or behind a pushing wave where the telegraph is hidden, not in the open where she closes with Q and Permafrost fires before your knockup lands.
