How to win lane as Sejuani against Sion · 52.11% win rate over 190 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Both champions are weak at Level 1 with no combo — take W, last-hit safely, and deny him any free shove advantage. |
| Level 2 | Even / skill | You can threaten a Q knock-up trade if his Decimating Smash is clearly on cooldown, but avoid dashing into a winding-up Q. |
| Level 3 | Sejuani | Your Q-W-E full combo stuns him before he can retaliate, but only when his W shield is down — time the engage around its cooldown. |
| Levels 4-5 | Even / skill | Neither of you has damage that scales with raw levels; trade when both his Q and W are spent, otherwise stack your passive resistances. |
| Level 6 | Even / skill | Glacial Prison at Level 6 gives you a ranged CC opener he cannot dodge — chain E stun immediately on landing for a legitimate kill threat. |
| First item | Sejuani | Sunfire Aegis or Heartsteel brings your trade damage high enough that a full CC chain after his first-item spike threatens a kill, not just a health lead. |
| Two+ items | Even / skill | You both become teamfight assets rather than duelists; your R placement onto carries wins fights, but never blow it into Sion knowing his zombie passive can absorb the follow-up. |
At Level 1 take W and play purely for CS — Sion is equally weak and his Q has a long wind-up telegraph, so you are not getting punished if you respect that animation. At Level 2 you can threaten a Q knock-up trade if his Decimating Smash is visibly on cooldown, but commit only if you are certain, because a charged Q into your Arctic Assault dash wins him the exchange. Level 3 is your first real agency: Q dash to close gap, W twice to stack Frost and slow him, then E to stun — do not throw this at a Sion who just raised his shield, wait for it to pop or time out.
