How to win lane as Sylas against Sion · 49.61% win rate (5,999 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
Free sustain lane and a premium ultimate to steal — bully with Q + passive, then carry skirmishes with his R.
Track: Sion's Q — Decimating Smash (10–6s cooldown). Charged knockup — break the channel or sidestep the slam.
Read from Sylas's seat: which stage windows this plan plays for against Sion.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Both of you have single-ability access at level 1 — Sylas Q-slows from distance, Sion begins charging Q, but neither can force a decisive trade without taking equal poke back. |
| Level 2 | Sion | Sion can charge his Q the moment your E first dash animates, so the knockup lands before your hook pull completes — he wins the level-2 trade cleanly every time you approach carelessly. |
| Level 3 | Sion | Decimating Smash knocks you up if he holds the charge, Soul Furnace eats your burst and detonates three seconds later, and Roar of the Slayer shreds your armour from 800 — your sustain cannot cover all three. |
| Levels 4-5 | Even / skill | Both champions have full kits now and the trade is decided by approach angle — you punish the charged Q cooldown with E into W, he punishes your aggression with knockup into shield detonation; neither pulls ahead cleanly. |
| Level 6 | Even / skill | Hijacking Unstoppable Onslaught gives you a steerable charge that knocks up harder the further it runs, but Glory in Death still gives him a second life after you kill him — real window, not a decisive one. |
| First item | Sion | Sion's Heartsteel stacks and growing HP pool outpace what your Riftmaker can convert via W heal — he out-bulks your sustain spike and your E hook simply gifts him a free W-shield detonation at this point. |
| Two+ items | Even / skill | Both champions scale into relevant 5v5 tools — your stolen R plus E stun is a two-hit engage, his zombie passive is a second life; neither side has a winning edge and the lane result carries over, not the scaling. |
At level 1 neither of you has teeth — last-hit safely and do not throw your E into him blind. The danger window opens at level 2: Sion can begin charging his Q the moment he sees your E first dash, and if you complete the hook pull onto him he knocks you up before your W even fires. Respect the charge animation at all times; you will hear and see him wind up. Your job levels 1 through 3 is to Q-slow him from a distance, bait the charged Q by walking in and retreating, then punish the cooldown with a clean E hook into W. If you eat the knockup you lose the trade badly — his E poke adds chip damage on top of a W-shield he can detonate to push you away.
