How to win lane as Sion against Jayce · 54.47% win rate (4,230 Emerald+ games, lolalytics, sampled July 2026) · Matchup data reviewed on patch 26.15
Eat the ranged poke behind minions, Q-charge once he's melee, and your knockup beats every hammer step-up.
Track: Jayce's Q — To the Skies! / Shock Blast (16–6s cooldown). His main poke. Dodge it.
Read from Sion's seat: which stage windows this plan plays for against Jayce.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Jayce | Jayce's Shock Blast through an Acceleration Gate chunks you hard at level 1 before your W-shield has any real value — farm at range and do not charge Q into him. |
| Level 2 | Jayce | He still out-ranges you at 2, and his E slot is 20s at rank 1 — Thundering Blow and Acceleration Gate share it, so walking up costs you either way. |
| Level 3 | Jayce | Shock Blast is 16s at rank 1 and the gate doubles its reach — you cannot close on a Jayce who keeps his range, so accept the deficit and farm it out. |
| Levels 4-5 | Sion | Your W-shield now absorbs enough of a gate combo to justify walking up, and your charged Q threatens his E knockback timing — Jayce must back off or take a stun. |
| Level 6 | Sion | Unstoppable Onslaught cannot be interrupted by his E knockback; you can R through his gate line and close the gap for a full charged Q brawl on demand. |
| First item | Sion | Heartsteel's HP stack makes your W-shield enormous and his burst combo trivially absorbed; you out-trade every melee exchange and his poke no longer threatens a kill. |
| Two+ items | Sion | Two tank items plus your zombie passive mean Jayce cannot safely poke in lane, push objectives, or duel you — he is permanently on the back foot and you dictate every engagement. |
Levels 1 through 3 are purely Jayce's game and you have to accept that. His Shock Blast through an Acceleration Gate hits harder than your W-shield can absorb at this stage, and his E knockback shoves you away the moment you try to walk up and charge a Q. Do not attempt to charge Q into a Jayce who is standing at max gate range — he will knock you back mid-charge and you lose the trade. Farm with auto-attacks and short W-shield tank trades only; your goal is to hit level 4 with decent HP and not give him a kill that fuels his early lead.
