How to win lane as Heimerdinger against Sion · 46.91% win rate (921 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
Turret-wall the Q-charge, grenade-stun the knockup, and out-poke his slow kit off the wave.
Track: Sion's Q — Decimating Smash (10–6s cooldown). Charged = knockup. Dodge it.
Read from Heimerdinger's seat: which stage windows this plan plays for against Sion.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Sion | He can charge a full Q knockup at level 1 before your first turret or grenade-stun exists, and his W shield sustains the trade - you have only one turret to answer it. |
| Level 2 | Even / skill | Second turret and slowing beams arrive, but his E shield-break poke and waveclear chip the nest back - a genuine wash where neither of you can commit. |
| Level 3 | Even / skill | Your grenade is close and your charges are stacking, yet he can still crash the wave and poke your buildings from range - it stays even. |
| Levels 4-5 | Heimerdinger | Three turret charges plus the CH-3X center-stun make any Q-charge walk-up suicidal - you zone him off CS and own the wave. |
| Level 6 | Sion | His ult is a long-range charge-up knockup that dives past your turrets onto an immobile, squishy yordle - the textbook way to delete you, often with a gank. |
| First item | Heimerdinger | Your UPGRADE super-turret and Liandry's siege out-zone his tankiness, and Hextech Affinity speed lets you kite his charged Q and ult line. |
| Two+ items | Even / skill | He scales into a tanky, useful frontline but doesn't out-stat the turret economy - the lane stays a positioning coin-flip where one ult-pick decides it. |
Sion's level 1 is genuinely scary because he can stroll up channeling a fully-charged Q knockup before your first turret even exists - with one turret and no grenade-stun yet, do not trade into that, just last-hit from max range. Once you have a second turret and the slowing beams online, the lane evens out: his E shield-break poke and waveclear can chip your buildings, but he has to keep walking into beam range to charge Q. Punish those windups with W micro-rockets and bank your third turret charge.
