How to win lane as Sion against Gwen · 49.86% win rate over 2,948 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Both kits are level 1 capable but neither dominates — Gwen's Q procs true damage on approach, your Q knockup punishes her CS greed; the outcome is coin-flip positioning. |
| Level 2 | Gwen | Gwen's E dash is online and her scissors begin stacking percent-max-HP true damage — she wins the short trade and her mist arrives to block your charged Q stun. |
| Level 3 | Gwen | With Hallowed Mist available, your charged Q knockup is neutralized in any straight trade; she can scissors freely inside it while you have no reliable way in. |
| Levels 4-5 | Even / skill | You have your full basic kit but no Onslaught threat yet; she has mist, scissors, and E mobility — neither can cleanly close, so the lane sits even if you play defensively. |
| Level 6 | Gwen | Her Needlework poke adds long-range percent-HP damage from outside your charged Q range; your R gives you an engagement angle but she can sidestep with E if she reads the vector. |
| First item | Gwen | Riftmaker's percent-max-HP empowerment comes online here — your HP passive stacks begin working against you, and she sustains through your W-shield with omnivamp. |
| Two+ items | Gwen | Full AP Gwen scissors erase your HP investment every trade; your passive zombie threat is irrelevant when she can safely poke from scissors range and re-enter mist on demand. |
At level 1 you have genuine threat — a fully charged Q knockup can punish her if she greeds for CS, but Gwen's Q true damage ticks and E mobility mean she punishes you mid-charge the moment she reads the windup. Farm with the tip of Q and accept that she will win most trades if she plays correctly. Your W-shield is your lifeline: pop it to absorb her scissors burst, then disengage rather than extending into a losing brawl. Level 2 makes things harder — she gets her Hallowed Mist and can block your charged Q stun from inside it, stripping your only real engage tool in a straight trade.
