How to win lane as Sion against Dr. Mundo · 48% win rate over 2,831 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Even / skill | Both champions are weak at Level 1 — Mundo's Q cleaver hits for percent-current-HP from range but your W-shield absorbs the trade; stay at Q-tip distance and neither side gets an edge. |
| Level 2 | Even / skill | Level 2 is still a poke skirmish — his Q comes out faster than your charge time, so W-shield a cleaver and look for a short trade rather than committing a full channel. |
| Level 3 | Dr. Mundo | By Level 3 Mundo's Q rotation lets him throw a cleaver on nearly every approach — your charged Q is too slow to answer safely, and he freely wins the health war from range. |
| Levels 4-5 | Dr. Mundo | Levels 4-5 are his lane: without your ultimate you have no reliable way to close the distance before he throws another cleaver, so you are CS-ing into a slow poke-down with no retaliation tool. |
| Level 6 | Sion | Level 6 Unstoppable Onslaught closes the gap before he reacts — charge into him with R, land the full-charge Q knockup, and convert the trade before his R Maximum Dosage can undo it. |
| First item | Even / skill | First-item Morellos or Thornmail means his Heart Zapper and passive regen no longer fully undo each Q-E trade — both champions spike here, making sustained trades a genuine coin-flip. |
| Two+ items | Dr. Mundo | Two-plus items Mundo pressing R heals back a massive portion of his HP in seconds and you carry zero percent-HP damage; teamfight as an engage anchor and leave the Mundo-kill to your teammates. |
At Level 1 Mundo's Q cleaver does percent-current-HP damage from a range your charged Q cannot answer without telegraphing the channel — respect the distance and last-hit with Q-tip range rather than walking into free cleavers. Pop your W-shield when he throws a cleaver during your Q charge, since the shield absorbs the burst and lets you complete the knockup. By Level 3 he is consistently winning the poke war: his Q cooldown is short enough that he can throw one every time you approach to CS, and your charged Q takes long enough to reach full power that an aware Mundo simply walks back. You won't lose the lane outright early, but don't force a brawl you aren't landing first.
