Dr. Mundo Build
Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Dr. Mundo is a boss so get the corporate Mundo skin asap.
I grab a Doran's shield because it has all 3 skills to help lane longer.
First Blood: Level 1 and 3 is a great fb level for mundo because you'll have masochism and lvl 2 cleaver which should be able to drop a good amount of damage. With Ghost and Exhaust, you should be able to sustain this damage on the target. I lane with Janna a lot and with well timed tornado/dmg add - Mundo can output a fair amount of damage.
Early laning: Generally lane with support or ranged though Mundo's harassment is ranged with cleaver so if laning with a melee, make sure to do the bulk of harassment if possible. Play in the bushes and last hit minions with cleaver or walk out and masochism and hit to ensure last hits. Stay in lane until you can get a spirit visage/lvl 1 boots or kindlegem/lvl 1 boots. Try to stay above 50% life until level 6 where you get ult.
Pros / Cons
Extreme Damage soak
% of life from cleaver
Ignite will own your ult
