How to win lane as Gnar against Dr. Mundo · 49.53% win rate over 531 Emerald+ games · Updated 2026-07-27
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Gnar | Mini autos plus Boomerang Throw and the third-hit Hyper proc win the opening trade, and early Mundo has no sustain and no dash to punish you. |
| Level 2 | Even / skill | Mundo's Q cleaver casts and passive regen start erasing your chip, so the trade evens out unless your boomerang catch and Hyper line up cleanly. |
| Level 3 | Dr. Mundo | Once his Q sustain is online he heals your Mini poke off and walks you down with E bonus damage whenever Rage isn't ready. |
| Levels 4-5 | Dr. Mundo | This is the form-RNG window — caught in Mini with Rage on cooldown you're a fragile ranged target his drain-tank kit runs over. |
| Level 6 | Even / skill | At 6 it swings on whether Mega is up: Maximum Dosage out-heals your rotation, so without a Wallop stun and wall-ult ready you concede the all-in. |
| First item | Dr. Mundo | His first drain-tank item plus Q heals let him out-sustain your Mini poke faster than your Mega windows can out-trade him. |
| Two+ items | Even / skill | Percent-HP cleavers and his R make him unkillable in a 1v1, but your GNAR! wall-combo teamfight engage keeps the overall matchup even. |
Levels 1-2 are yours: Mini's ranged autos plus a single Boomerang Throw and the third-hit Hyper move-speed proc let you land a free trade Mundo's body can't answer before his sustain is online, and he has no dash to close on you. Catch the boomerang on its return for the cooldown refund and keep chipping the wave so he eats minion aggro every time he steps up to cleaver-last-hit. By level 3 it tightens — his Q (Infected Cleaver) casts and passive regen start healing your poke off, so stop trading for chip and only commit when Rage is climbing toward Mega.
