How to win lane as Cassiopeia against Dr. Mundo · 44.12% win rate over 136 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Cassiopeia | At level 1 he has one weak cleaver and thin regen — my Noxious Blast poison on his step-ups chips faster than his passive refunds, my single clean stage. |
| Level 2 | Even / skill | Skill lane: my Noxious-Blast-into-Twin-Fang chip still beats a low-item Mundo, but his cleaver poke and passive heals trade back enough to keep it close. |
| Level 3 | Even / skill | Even — my full primed Twin Fang rotation is real DPS, but his percent-HP Infected Bonesaw and regen mean neither of us truly wins the trade yet. |
| Levels 4-5 | Even / skill | Still skill: I drop Miasma to ground his approach and out-chip him, while his cleaver poke and heals keep him from falling behind. |
| Level 6 | Even / skill | Petrifying Gaze lets me survive his cleaver-and-walk dive, but Maximum Dosage heals through my kill window — I live, I don't kill, so it stays even at best. |
| First item | Dr. Mundo | His first HP item plus percent-max-HP cleavers and passive regen outpace my Twin Fang chip — he stops fearing the poke and the lane flips to him. |
| Two+ items | Dr. Mundo | Maximum Dosage's grey-health heal makes him unkillable while I stay boots-less and resistance-free — I can't out-DPS the sustain and he walks me down through the slow. |
Levels 1-3 are the only window the math favors me, so I have to bank a lead here. Noxious Blast on his last-hit step-ups stacks poison faster than his passive cleanse-heal can quietly refund, and the move-speed on a champ hit lets me slide out of his cleaver's slow. Dodge Infected Bonesaw above all — it's percent-max-HP, it ignores how few stats I built, and every one that lands is free poke plus a slow he uses to walk me down. Don't greed an all-in; he has no real commit threat yet and I just need to win the poke war before HP items neuter it.
