How to win lane as Sion against Mordekaiser · 49.97% win rate over 3,044 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Neither champion has a reliable level-1 engage — Morde has no dash and your charged Q is too slow to land on a patient opponent, so the opener is a farm-or-die skill check. |
| Level 2 | Mordekaiser | His E pull into empowered Q isolated bonus is online at level 2; trade only with your W-shield up or you eat a chunky combo for nothing. |
| Level 3 | Mordekaiser | At level 3 he has E-Q-W available and can combo you for half your HP if you let him step in — respect the range, last-hit safely, charged Q from outside his pull distance. |
| Levels 4-5 | Mordekaiser | Levels 4-5 he roams for a zone pick or just bullies you off CS; your charged Q has no target to punish and his W sustains through your poking, so accept the farm loss and stack HP. |
| Level 6 | Mordekaiser | Realm of Death goes live and it is his best window all game — low-HP Sion dragged into an isolated stat-steal duel usually dies; only fight the Realm with W-shield ready and a charged Q stun prepared. |
| First item | Mordekaiser | His first AP item makes his Realm duel near-certain-kill if you enter below 60% HP; Heartsteel or Hollow Radiance must be rushing so your HP total tilts the 1v1 back toward a contest. |
| Two+ items | Even / skill | Your stacked HP total and zombie passive make you a legitimate frontline threat he cannot burst or ignore — the matchup converges to a coin flip at 2+ items, exactly what the 49.97% WR reflects. |
Levels 1-3 are the one window where neither of you has an automatic advantage — Mordekaiser's E pull is short range and he has no dash, so he can only hurt you if you stand directly in his Q slam hitbox. Keep max distance, last-hit with the tip of your Q, and only commit to a charged Q knockup if he over-extends to zone you. W-shield his Q hit the instant his E lands, because the isolated bonus damage is the real chunk — absorbing even half of that with your shield completely neutralizes the trade. His level 3 all-in (E pull into Q into W shield pop) is his first real threat; back off at low health before you gift him a kill he can snowball into Realm dominance.
